Thank you for this resource, it helped me re-solder a loose power jack in my minilogue. One tip - right after you take off the front panel, set aside the clear plastic light guides near the octave switches and voice mode buttons (you can briefly see them @4:49). They are not glued in and could be very hard to find if you drop them accidentally.
Nice tear down demo Markus. Thanks. I'm glad to see more and more manufacturers using solid type electrolytic capacitors in their designs. That means that 40 years from now, those should all be as good as today, and not need replacing like in many classic analog synths from 40 years ago... I just wish that Korg could be coming out with The Logue (full 8 voices version of the Minilogue) in the near future...
I knew I wanted this synth the first time I saw it. And I was really hoping you'd get to tear into one Markus. Your video did away with all doubts. I must have a minilouge! I'm really happy for you, thanks for the video! =D
+brickscratch Fondeling these black n white old fashioned machines is how I fell in love with music making 30 years ago. Granted, u have everything I need in my pad...well..almost everything. ;)
This gentleman impressed me very highly. I bought this model yesterday, so it's so nice to know that I've purchased something of such excellent quality. Had it not been for him I could only have guessed at such a thing and would have to have gone on KORG'S reputation alone. Outstanding! So it's a thumbs up, and one new subscriber. Thank you sir.
Thank You Scott. I hope you get lots of good use from it, it really is quite an amazing synth for its price point. and as you may know I get no sponsorship from any of the keyboard manufacturers so I do not have to thumbs up any of them for personal gain. anyways have fun.
The direct sunlight warning was probably because you can't see which buttons are lit up in bright sunlight. Saw a video where a guy was struggling because of that during his show, lol. Great video. I love seeing the inner workings of synthesizers and electronics.
Another wonderful video Markus! As an old electronics engineer from the 80's I just find your videos so great. They inspired me to take a punt on an old Korg DW-8000 from 85 on ebay that was not working and sold for parts/repair. Long story short found a dead back battery, a s/c on the main board, cleaned it up, fixed the broken keybed and its back up and running so ... thanks for the inspiration mate. Look forward to more of the same... cheers
+TheReynoldsTV Brilliant. Im so pleased you got the DW-8000 working. Its amazing to see the difference in electronics from the 80s to today and its forever evolving im sure one day you will just be able to print out a whole circuit from a printer that has carbons metals and semiconducting materials instead of plain ink. Maybe this will be invented in our lifetimes ?. who knows.
Really great video. I'm impressed by the build quality. Especially after the MS20 Mini, which was of horrifying bad buildquality. I sure hope this will be the future quality by Korg after a period with wobbly knobs, lousy outputs, and build in speakers, etc. Best wishes and thumbs up. Soundrookie.
Exceptional teardown this time, thanks.... Makes the Minilogue even more of a no brainer. Also nice to see that the plank comes off the back without leaving a gaping hole. An added bonus for those who aren't really fans of the decorative wooden bits.
+reverse:pool Thank You. I think it would make a nice letter box on a door. sorry thats just my bad humour. overall I think it is a great little synth and sounds very good.
Love those pots and switches. This synth... Along with that Arturia mono monster are really moving the game along. Moog are looking outdone at their own game by Arturia... And it won't be long before Korg are nipping at DSIs heels but probably with something fully analogue! I look forward to you doing a tear down of the new Arturia synth! I know you like that machine! Greta stuff as always Markus
+hydorah That Arturia looks amazing but I have to buy everything myself ( manufacturers wont loan me one to strip down) . If I can get the money I would be interested in the Arturia.
If we lived close I would certainly send my items over to you for better demo's but then I would need to take your gear apart and that would keep me busy for years LOL :-)
I own one of these and they are a fantastic synth. Normally when I mess with synths it takes me a while to put together a sound I like but with this little guy great sounds just keep popping out.
As a complete newbie to modern electronics (I last built a terrible oscillator circuit on a breadboard in the 80s), do the oscillators, envelopes, filters, and amps happen in the small ICs you couldn't identify? Given that you mainly identified what I assume are digital micro controllers, I am wondering where the analog bits are in the design. Are the micro controllers there to send voltages to the analog circuits from memory or from the signals from the pots and switches above? Great videos.
Thanx for the teardown! It´s like what we gonna be seeing in new synths...rather low end uCs, but many of them, as they are cheaper than a single and obviously more powerful design. On top of that, it´s modular for the manufacturer. If they want to do an 8-voice device they just need to copy&and paste the layout 8 times, or put one voice on a board and cone that board...
The monologue is one of the few if not the only quality polyphonic all analog synth that is in a great price range. I love mine. The few bugaboos are no re routing capabilities so no mod matrix besides a slider for cutoff and such. And the slider it self is a silly thing to make cheap on this board but I did the same mode and it seems more stable but def a good buy. Also someone mentioned no sub octave but it does have one in mono mode your same knobby to change the arp patterns and detune becomes your level for your sub octave wave (I believe it's actually a sub of Osc. 1 but could be wrong) so. Also the first one my buddy had when the came out had very snappy envelopes that clicked in a bad way. The updated the firmware and fixed it nicely. But I received mine a month ago and it is def been removed from the newer shipments or just has the latest update. Awesome synth!
This is the first takedown you've done, for a product I was already intending to purchase, and what you found reassured me, like the metal pot posts, for example. Really nice video (I didn't seem to have any problems with resolution, btw.)
btw the chords u played while it was fast forwarding while u were putting it back together were v nice! I like the little DIY fix to the pitch bend too! gr8 vid as usual!
+CYPRN Hello I thinkk they were the opening chords to David Bowies space oddity Fmaj7 then Em. I already have people asking if I will to the pitch bend fix for them. but the video shows them how to do it themselves and I guess Korg will implement that in future production hopefully.
Very informative! One thing that seems quite ironic though is that despite this being an analog synth, it has so many processors that it must be more powerful than old supercomputers :p
Great channel. My new favourite! I have a couple of vintage Urei units that need some servicing and watching your videos is great guidance for troubleshooting.
Thank you very much for that very interesting tear down! Great to hear that you are impressed by the generell build quality & that you get lots of synth for the money. When I compare my 80ies Juno60 or 70ies Elka X705 with the Minilogue, the electronic is now real mini, although analog. Looks like It does not matter if 1 or 4 voices, probably 8 voices would have also fitted in the case. When it is possible to produce a real 4 voice polyphonic analog synth with aluminium, real wood and radio controllers, many knobs, slimkeys & oscilloscope at that price, I wonder where the other competitors in this price-range are ???
+VolcaRock I agree I dont know how Korg are making these things and making any money from them. theres shipping taxes and shop percentage to come out of that end price. still i like the idea of an 8 voice version
Unlike Roland who needed Malekko & other 3rd party, Korg has a developer team with massive experience. They started with Monotron-gadgets followed by Monotribe, MS20mini, Volca-Series, Odyssey and now ML.They make profit on the mass market. I ask myself what price is 1 voice on the board (just hardware)? about 20$? Price is 500$ for 4 voice Minilogue would be 440$ for a 1 voice Minilogue (still good price, but not a no brainer) But what if they would make an 8 voice? I am sure we will see a Maxilogue with 8 or even 12 voices on the next NAMM for attractive price.
+VolcaRock I think the competition will be coming thick, soon. Before, or at, NAMM 2017 i think several competitors will announce a counter-move of sorts. Looking back over the last several years, each year 1 company have had _the_ gamechanger of the year, leaving very obvious traces in the market and the competition in the following year. Ofc it's a circular series of reactions, but a few stand out. And this year i think it will be the Minilogue. Imho in 2012 it was the Arturia MiniBrute, kickstarting the analogue renaissance, and a subsequent lashings of cheap analogue mono synths, from companies they hadn't touched that market segment for years. In 2013 i'd argue they took it again with the MicroBrute, pushing the boundaries for cheap analogue, the response to which brought the Volcas among other. The CV-ports also helped bring eurorack into the minds of people that would previously steer clear, and have had a hand in its resurgence. In 2014 i think it's the Roland System-1, not only did it revitalise hardware VA as a whole, by bringing it closer to the analogue competition. But it reintroduced the notion of polyphony in the lower pricebracket, at that point utterly dominated by analogue monosynths. It _may_ not even be a stretch to think it has something to do with the Minilogue being 4-voice poly. And the ACB technology will yet do more good. 2015 is harder to gauge a single entry pulling more weight than the rest. There's many good contenders from the Prophet-6, over the Roland JD-X's, Boutiques, Yamaha Reface series and ofc the KARP Odyssey. But i think my choice would be the Reface DX, as i think it will be the harbinger of several FM synths to come, perhaps for the 1st time in a long time, even challenge the monopoly of the subtractive synth. Volca FM any1? Now if people actually read this novel, they're probably thinking something like "what about the MS-20 mini?". The list isn't based off sales numbers, where the MS-20 mini did very well no doubt, probably better than all but perhaps the MicroBrute. However it didn't really bring anything new, and it didn't really change anything, which would be the main requirement for being a gamechanger. Now with the Minilogue more than likely being this years gamechanger, i predict the following: Novation finally bringing the PolyStation. Roland have 2 potentially promising venues of retaliation, both the ACB-VA and the analogue from the hybrid JD-X's. Timing wise it's most likely to be a development on the ACB (System-8/10?), but perhaps they'll make a Aira hybrid with both ACB and real analogue? Or take the analogue voiceboard from the JD-XA and put in a smaller knob-ladden keyboard. Yamaha will no doubt run with a bigger stronger FM synth, probably somewhere between the original DX7 and the Reface DX in terms of size and features, expanding on the interface-improvements with more hands on features to compete with the nice interface of the Minilogue. Essentially each playing into their own strengths to challenge it on feel, interface and playing-experience, rather than trying to level the playingfield.
Korg was Kickstarter of the analog renaissance for the cheap mass market with Monotron in 2010 followed by Monotribe in 2011! And then 2 years later in 2012 Arturia made the Microbrute And the MS20mini was something new, because before its release nobody believed that a global player would make a 70ies remake of an analog synth especially at that price! That was more unbelievable than the ARP Odyssey because it was the first. There have always been amazing VA synths since at least 10 years , so I would not pay too much attention on them (when talking about anlog) even when the technique is now better. Analog is a market which survived (like vinyl and tube amps) and the Minilogue is the gamechanger for budget analog poly. Musicians who spend 2000$ or more on a synth will do that anyway with or without Minilogue so Prophet06, OB6 are out of competition. A big sucess on the mono market is Mother 32, I do not know any other facebook group which growed so fast! But it’s mono and Rolands Hybrid has a minimal analog section only . Reface and Volca FM, is fine, but other technique. I am interested what will happen in the budget analog polymarket. Akai was awfully bashed and even with a AX60 remake it will be hard for them. Yes, maybe Novation with Polystation, but Roland will not produce budget analog poly. I guess THE ONLY real competitor who is actually able to produce at the same cheap price &same quality as Korg will be Behringer/Midas with their 6 voice analog poly with Rolandfilter clone. Coming soon!.
VolcaRock How many products have you seen with any relation or competitive value to the Monotron or Monotribe? The answer is none. Ergo they didn't start the analogue renaissance. Also it doesn't take 2-3 years in a market as competitive as this for the competition to react. Firmly reflected in my list that showed the emergence of several analogue monosynths within 1 year of the MiniBrutes, and subsequent circles of reaction. Never taking anywhere near 2-3 years. True the MS-20 mini was the 1st cheap copy of a 70's/80's classic, with no real alterations or improvements. How many have taken that up and followed or copied? Again the answer is none. There's been several nods at the past, but Korg is still the only to make a largely unaltered copy. Neither this, nor the KARP, are hardly unbelieveable. But the KARP atleast brought a different set of waves, it had a bunch of improvements that helped shape the MS-20M and the Minilogue. And the cooperation elements may have had a hand in the Sequential/Oberheim cooperation resulting in the OB-6. But as i said, there were less of an obvious winner in 2015, the Reface DX being the closest to a gamechanger imo. Roland is indeed unlikely to do a cheap dedicated analogue, but never the less did their ACB tech influence the market overall. And while it'll never outdo or replace proper analogue on its own battleground, digital has its own number of strengths that become increasingly appealing, the closer it comes to analogue in sound and feeling. So to assume it won't influence or change the market simply because it's not true analogue, is a big mistake, and quite frankly a bit narrowminded. Like i said before, it's not a stretch of imagination to think the Minilogue is Korgs response to the System-1, effectively saying "we can do 4 voice poly too, but we've outdone you with it being a proper analogue". The high end market, more often than not, stroll at its own pace, doing its own thing, and only slightly influenced by competition. The customers go for a particular sound and feeling, geared towards high end _instruments_. While some innovations and ideas filter down to the cheaper market, it's often a slow evolution over several generations, compared to the fastpaced changes and experiments going on in the cheaper mass market. Again it's narrowminded to think just because the competitions reaction to the Minilogue won't necessarily be analogue, that it won't affect the market and pose a credible threat to the Minilogues sales (i still think it'll be 1 of the all time best selling synths). There are afterall people, particularly the growing number bored with all the analogue monosynths, that will see Rolands VA/Hybrids as a viable alternative, or going for the difference in FM synthesis, we're likely to see more of from Yamaha. Plenty of people around that don't care whether a synth is analogue or digital. And to discount that any company could bring out a similarly cheap analogue poly, would also be a mistake. Just see how surprising it was this time around. But there's nothing to stop a number of big players doing the same out of the blue. Except if you look at the likes of the DSI Tetra, it won't necessarily be out of the blue.
Fantastic work as always Markus! I was looking forward to this...Very happy to see that it's quite good quality under the hood! And I liked the Magnetic Fields joke...
Very nice video. Just bought one and it's great to see such a nice piece of engineering. One tip: put some additional heatshrink on the spring levers and you'd get rid of the clicking sound completely.
so you put the heatshrink the way Markus did in this video and you additionally "covered" the two sides of the spring in heatshrink? DId you make any pictures that i can see somehow? Is it enough to remove the Aluminum lid or do i have to go deeper (like removing more than the Aluminum plate) ?
ha ha..me too..i remember when i was 12 years old and taking my dad's philips reel/reel recorder apart.. out of pure curiosity, then put it in a box back on top of his wardrobe :-) i love seeing how stuff works..
Awesome Markus u was waiting for this tear down, the built quality of the interface very good, above this price point, nice to see the pots and switches can take abuse and can get replaced if needed
Thank you Markus, great tear down again. I believe that Dave Smith opted for opto-isolators( see how I played with words there! ) to eliminate mains loop hum. My brother has a mains loop hum on his set up, so I will tell him to disconnect his usb stuff 1st to isolate the cause.
When you think about it, it is really amazing that Korg can produce the Minilogue and sell it for under $500.00. I mean, so many parts involved. I look forward to the day, if that day comes, that Korg produces a six or eight voice Prologue or Maxilogue that has 61 full sized keys :)
Amazing! It's my next synth and I was afraid about the pots, a point that took me some problems in anothers synths like the Microkorg (that if any pot was fail, all the functions on the synth came on aleatory value changes and a pot replace were involve a real problem because it's not a simple welder-and-ready work). After your video, I'm more calm! :) Greetings from Argentina
Just installed a piece of heat shrink around the spring post on my Minilogue! Great idea! Also lubed the spring before re- installing it. TBH, I was just looking for an excuse to void the warranty. It was worth it
+markusfuller The OB-6 definitely kills the Minilogue, as far as sound design. Stereo synths always win, in my books. But who can afford the damn thing?! But the Minilogue is wonderful, as long as you can get over the now infamous EG clicks. I hope I can pick one up some time this year.
Awesome video Markus! Very nice explanation. Really enjoyed it. My slider is not working properly. When pitch is assigned, it oscillates rather random and it suddenly stops from reacting to any movement. Mechanics seem fine so thinking its software probably. Do you know how I may be able to disable the slider either hardware or software? The only work around is to assign it to a delay parameter and disable the delay but it is really annoying. Thank you sir in advance.
Just got one of these, and the final a# key doesn’t work on lighter presses. Might have to tear it open and clean the contact. Do you have to take off all the buttons to remove the top? Also, great video!

Great video, thanks. The build quality seems really good, I'm just wondering if the black bottom plate of the synth is made of metal or plastic.
You make it look so easy with your FWD teardown....:-) In real life i tried it and really it felt longer than in the video....:-) Btw about the rattle switch. I did what you shown and took it further. I put some heat shrink tubing on the springs on both sides and also the same principle i did on the little white slider-knob that the spring is keeping in place. I made a thin little cylinder formed ring made of fabric tape that i secured with a drop of glue and covered the surface of the white slider plastic knob-slider where the two spring arms touch the white plastic . Not it sounds like an expensive synth :-) Btw out of 1000+ Thumbs up, 9 Thumbs down on a teardown video that is for free.... That shows us that at least 0,9% of the population will never be happy. It`s genetics baby
Glad to see they for the most part seem to have avoided the mechanical rotary encoders here. I've had plenty of problems with those on other gear, getting noisy over time. The mechanical ones are really cheap, and while they may be gold plated, the plating apparently wears and/or it oxidizes to the point where the connection goes bad in record time. The Korg Electribes and the Electron gear have a lot of flakiness problems with them. There are actually some inexpensive optical rotary encoders available, but they require power for the LED, and it seems all to often the designers don't use them.
Great video and very informative. This is the first video that has excised me of that inherent fear all users have as to the internal nature of these beautiful tools. Thank you.
+Taren McCallan-Moore Thank You very much. I am completely independent and receive nothing to say things are good. most items are what I have purchased myself and if they do look well made that is my unbiased true opinion. I was looking forward to opening this up and truly thought there would be cost saving going on inside especially for the price of this synth but was real pleased to see that Korg had genuinely made a good value product in the minilogue. This is a synth I will keep for life now I am getting to play around with it, it does sound really good.
Thank you for your reply Markus, your insight is very useful and your enthusiasm an inspiring pleasure. I wonder if I might tap your knowledge if I may? I've just purchased a Roland CR-5000 and the question that I have is regards the fact that it's ac100v. Can I use a standard 13amp 250v adapter or do I need some kind of transformer? I would appreciate any thoughts you have about this. One final question, regards your repair service, how might I find you for future reference? I'm in the south of England, Kent. All the best.
Hello Taren, normally You must purchase a step down transformer. if you use a plug adaptor you will still get 250volts to your CR-5000. I am not 100% sure but if you know someone who will open it up the power supply is steel cased top right and there may be a way to change the Taps on the transformer to allow it to work with 250volts. that would mean unsoldering certain wires from the transformer and attaching the correct ones for 250volt operation. if this option is not on the transformer then you need to purchase a step down transformer that you plug your 250volts into and get 100volts out. they can be bought from places like Maplins electronics or off Amazon etc. Good luck :-)
hi great vídeo, im impressed of your knowledge. I've a minilogue and have quite an annoying background noise when there is no sound playing. tried the korg ms 20 mini to check if it was normal, but the ms 20 did not have any kind of background noise (as I was expecting). could my minilogue have some kind of fault? I'll really appreciate some help with this issue. many thanks
Good one Markus! I was wondering about the dimensions of the boards, the four plus one processor one in particular. I would fully expect a eurorack keyboardless follow on, so wonder if this pcb woukld fit? The reuse seems a no-brainer in the design, like with the Roland System 1 and then the System 1M. Perhaps that also explain some of the unpopulated components, audio paths, or CV in or outs, etc? Me thinks i'll wait a few months, to see what might appear, for me a modular of this is even better.
Very informative, thanks! I'm just wondering whether you found a dedicated delay section. From some of the demos and the mention of the noisy delay, I wondered whether it might've been a PT2399, as used (I think) in the Monotron Delay and a bunch of cheap pedals etc. Notoriously noisy and quirky, but with their own charm and an almost low-fi tape echo sound.
+voltlife Hello I am not using the onboard Delay I have been experimenting with the output going through chorus - delays - reverbs - phasers etc etc and its starting to sound like a completely different synth.
Amazing teardown. I have a minilogue xd and I have an issue with the first 2 octaves of the black keys. It seems like they need more pressure to work than the last octave. They still have velocity so that's not the issue, but I was wondering if you managed to figure out how to change the tension/trigger point of they keys on the keybed since I didn't see a key disassembly.
In case anyone is wondering. The keybed is the same as the one on the Minilogue from what I could see. No issues with the switches or keys, but there's this felt pad that the keys bottom out on that's a tad too tall on one side of my keyboard. I'd reckon that with time this will wear in and become proper. So the fix is just to play a lot.
Love the video. I always want to know what the insides of my electronics look like, but don't want to risk disassembling them just for curiosity's sake.
Thanks for making this teardown video, it came really handy. The program knob shaft on my minilogue has broken and I'll be replacing it soon, do you happen to know what kind of potentiometer it is? Might be a rotary encoder but I'm not sure.
Im sorry I do not know the exact version that korg is using and there are many different types. best to look at the original and see if there are any words or numbers on there that may help in searching for the correct version. I hope you manage to get it repaired. best wishes.
Hey Mark I wanted to know if you can make some videos on the Korg Volca series (I am a new proud owner of the Keys and Bass!) and to see what are some of the hackle components that each device is capable of? Thank you!
Thank for showing the inside of the Minilogue. Great video, as always. They are a little bit expensive, but have you ever opened something from Waldorf? My Streichfett says it was made in Germany (I think they all say that), but I wonder if it was only the final assembly, or the whole thing. Cheers.
Great! The Streichfett is all digital, so I'm betting it will revolve around only one big IC at the centre... I'm sure it will be a great video. Cheers :)
Excellent video as always Markus! Thank you very much, you really are doing a service to the synth community. Quick question! While you were on that main panel board, did you notice what size the LEDs are? I want to do a color mod to mine and I'm assuming they're 0805, but i can't tell from any pics (or find a schematic). Thanks in advance for the reply!
Excellent video as usual Mark! The only mistake I could find was that you said the USB port carries Audio. It only carries MIDI. Must have been a force of habit from the Roland synths!
Hi Markus, thanks again for an awesome video. The Kylie Minogue (as I like to call it) is definitely an attractive synth. Would be interested to know if those arm processors are responsible for the generation of the waveforms (does that then contest what we would consider to be analog?)
I really like the Minilogue, and now we know it's put together nicely. The only thing it's missing, in my opinion, is a sub oscillator. Would reallly like a sub on this to fill it out as a complete analog synth.
Of course they're complete analog synths. The obvious reasons why have nothing to do with not having a sub oscillator.. the OB8 had 8 voice, the prophet-5 had 5 voices, the minimoog had 3. Granted, they were 2 grand more money for those extra voices, but I'm not asking for another complete voice, just a sub osc.. which aren't that expensive or involved to add on. I'd pay another 100 bucks if the Minilogue had a sub to go with the 2 VCOs.
I was thinking about rehousing my minilogue into a rack unit. Would the synth work without the board that has the pot's, and the keybed? I was planning to use a computer editor for patch programming and switching.
Hi Markus, the oled screen on mine doesn’t work at all and I’m thinking of ordering from US. I don’t have the monologue to hand but remember the screws holding the top plate on we’re weird. Do they require an Allen key or is it something else I need ?
I'm considering purchasing one of these for my first hardware synthesizer and I have a question about using it with Reason Essentials. I see that it has a USB type B plug which is the same as my Novation Launchkey 49 Mk2. If I were to plug this into my computer, would I be able to control it with my Novation product? I really enjoy it and would prefer to keep as my main controller! I also would like to know how I would go about getting the audio into my DAW, would it simply be a matter of using a 3.5mm jack adapter to a microphone port? Thank you! --David. P.S I do not have an audio interface.
+venomblademedia Hello The USB on this only sends midi data to and from the PC, It does not send any audio data. you will need to have an audio input on your PC or some way of grabbing audio to USB. many modern PC have a mic input that is also a stereo input but dont take my word for that as I do not know the PC you are using. you will have to check if your PC has a stereo line in. or if the Mic socket doubles up as a line input. remember the minilogue is only Mono not stereo though the headphone output will split a mono output to 2 channels.
Hello the bracelet is connected to the Earth/Ground . it is to prevent electrostatic discharge that can sometimes corrupt microchips. its just a precaution. many thanks from markus
I just bought on e of these second hand and the slider doesn't work at all although its spring\action seems to be ok (it moves back and forth like it should). Do you recall\think that it could have popped off the interior mount (the one you put shrinkwrap around)? ie is there clearance enough for that to happen?
I definitely feel the same way about the construction of the slider when I got mine :( I'd much rather have a classic mod wheel. You don't get nearly as much control and you have to hold it down so you can't play with both hands if you want full modulation on the fly. All in all though, fantastic synth for the price. I love mine.
hi Markus! how do you think they did to reach that low price? Are electronics cheaper now than back in the days? thank you for all your videos, Im studing electronics and Im learning a lot seeing all that synths inside
yeah the components are really cheap now, a reel of 5000 resistors is like $12.00, and it only takes maybe 15 minutes to build the board on a Smt machine. But the price has a lot to do with the company's overhead. So Korg may be in a better position than smaller companies like Dave Smith Instruments.
+Keepin' Soul Hi I agree with friendofCHAKA , the components are quite cheap and I uess the biggest cost is research and development. also its sometimes a good marketing move to make a little bit of profit on a lot of items than to sell just a few at a high profit margin, I think Korg are well placed to gamble on selling lots for lower prices. There is a shop here in brighton that will fit a new battery in your watch and charge you £1 all in (he is always busy) then there is H-Samuels the jewellers who will sell the same battery from the same manufacturer for £12.99 and say with a smile they will fit it free. guess who sells the most batteries. and consider they only cost £0.08 each to buy in bulk.
+markusfuller thank you both for the reply. Check Attack Magazine, Korg engineers talk about this video! One engineer talks about how using the ARM microprocessors they have cut some costs
The "direct sunlight" warning is because the aluminum absorbs and transfers heat very well, and fully analogue synthesizers can be detuned if their temperature changes too much. Oddly, though, most of the complaints I've seen about the minilogue detuning have been because of excessive cold.
Thank you for the great teardown video, Markus! This seems pretty easy to mod to remove the awful "slim" keys and make a module version out of, wouldn't you say? Take apart, saw off the bottom bit of the front panel and plastic case, and put a nice wood plate in front to close it up... I didn't see anything in the teardown that would prevent that. What do you think?
Ever since I heard that korg was making a 4 voice analog poly I wanted to see what a modern day analog poly looks like, thanks for showing us this fine synth. What got me excited from korg though is the volca FM, now that I want
It is digital unlike the rest of the volca series excluding the sample but would still be very interesting to see what chips they are using.mi love the fact that you can load up your old sysex patches from the dx7
+joeboygsxr Hi I have no volca's I like them and am intersted in them very much but just have not yet got around to buying one yet. I will do one day as I think they are brilliant devices.
Thanks Markus, big fan of your channel! Keep up the good work man! I don't know if you've seen it, but the designer(Tats) references this/your video in this article, pretty cool:)! : www.attackmagazine.com/features/long-read/the-democratisation-of-synthesis-korg-designers-on-the-making-of-the-minilogue/
purpleibby Hi yes I have read that interview with Tats , he is a brilliant guy and I think there is going to be more incredible music gear coming from the mind of this inventor over the coming years.
I couldn't tell from the video how so many potentiometers were handled by the UI. Are there any extra ADC chips or some analog signal multiplexers or such on the PCB? Are any of the signals filtered before going into the ADC?
+krakulandia Hello from what I remember the top control section had one ARM chip and a couple of smaller chips but I think the pot controls was maybe multiplexed by the arm processor where it would check the resistances of all the pots one at a time but at very high speeds. Thats just a shot in the dark but may be how its able to read so many pots.
That wobbly slider really is an issue... on my Minilogue, it doesn't always come back to 0... stops at 2% sometimes and I have to manually zero it. But thanks to this video, I know how to fix it. Just need to get my hands on some heat shrink in the right size...
Thank you for this resource, it helped me re-solder a loose power jack in my minilogue. One tip - right after you take off the front panel, set aside the clear plastic light guides near the octave switches and voice mode buttons (you can briefly see them @4:49). They are not glued in and could be very hard to find if you drop them accidentally.
"The more wood you save, the more they can put on synthesizers." - classic!
Nice tear down demo Markus. Thanks.
I'm glad to see more and more manufacturers using solid type electrolytic capacitors in their designs. That means that 40 years from now, those should all be as good as today, and not need replacing like in many classic analog synths from 40 years ago...
I just wish that Korg could be coming out with The Logue (full 8 voices version of the Minilogue) in the near future...
+AlainHubert If only we could have longer lasting Caps. that would solve a lot of problems.
Invent them markus!!
I knew I wanted this synth the first time I saw it. And I was really hoping you'd get to tear into one Markus. Your video did away with all doubts. I must have a minilouge!
I'm really happy for you, thanks for the video! =D
+Jakob Haq Thanks Jakob, It really is a great little synth for the price.
+Jakob Haq I'm surprised you have time for these old fashioned black & white instruments :p
+brickscratch Fondeling these black n white old fashioned machines is how I fell in love with music making 30 years ago. Granted, u have everything I need in my pad...well..almost everything. ;)
This gentleman impressed me very highly. I bought this model yesterday, so it's so nice to know that I've purchased something of such excellent quality. Had it not been for him I could only have guessed at such a thing and would have to have gone on KORG'S reputation alone. Outstanding! So it's a thumbs up, and one new subscriber. Thank you sir.
Thank You Scott. I hope you get lots of good use from it, it really is quite an amazing synth for its price point. and as you may know I get no sponsorship from any of the keyboard manufacturers so I do not have to thumbs up any of them for personal gain. anyways have fun.
Markus, you're the David Attenborough of synth repair! Thank you very much for this series of videos, truly one of the best channels on RUclips.
Blindfold Knobs
The direct sunlight warning was probably because you can't see which buttons are lit up in bright sunlight. Saw a video where a guy was struggling because of that during his show, lol.
Great video. I love seeing the inner workings of synthesizers and electronics.
I bought one of these the other day. It comes in a week or so. I'm glad to hear it has the Markus seal of approval!
Brilliant Video. I highly appreciate your extreme politeness and soft narration(like a story teller).
Another wonderful video Markus! As an old electronics engineer from the 80's I just find your videos so great. They inspired me to take a punt on an old Korg DW-8000 from 85 on ebay that was not working and sold for parts/repair. Long story short found a dead back battery, a s/c on the main board, cleaned it up, fixed the broken keybed and its back up and running so ... thanks for the inspiration mate. Look forward to more of the same... cheers
+TheReynoldsTV Brilliant. Im so pleased you got the DW-8000 working. Its amazing to see the difference in electronics from the 80s to today and its forever evolving im sure one day you will just be able to print out a whole circuit from a printer that has carbons metals and semiconducting materials instead of plain ink. Maybe this will be invented in our lifetimes ?. who knows.
Thanks for this teardown Marcus, your video was actually what finally convinced me to get one. I was glad to see it's well built inside!
close to magnetic fields.....knew what was comeing ,but i still cracked up at it!
+Garry Field HAHAHAHAHAHAHAHAHA!!!!)))))
I didn't know, but I just as cheerly got happy.
Really great video.
I'm impressed by the build quality. Especially after the MS20 Mini, which was of horrifying bad buildquality.
I sure hope this will be the future quality by Korg after a period with wobbly knobs, lousy outputs, and build in speakers, etc.
Best wishes and thumbs up.
Soundrookie.
+TheSoundrookie ThankYou very much. yes this certainly looks better especially for the price.
Exceptional teardown this time, thanks.... Makes the Minilogue even more of a no brainer.
Also nice to see that the plank comes off the back without leaving a gaping hole. An added bonus for those who aren't really fans of the decorative wooden bits.
+reverse:pool Thank You. I think it would make a nice letter box on a door. sorry thats just my bad humour. overall I think it is a great little synth and sounds very good.
Love those pots and switches. This synth... Along with that Arturia mono monster are really moving the game along. Moog are looking outdone at their own game by Arturia... And it won't be long before Korg are nipping at DSIs heels but probably with something fully analogue! I look forward to you doing a tear down of the new Arturia synth! I know you like that machine! Greta stuff as always Markus
+hydorah That Arturia looks amazing but I have to buy everything myself ( manufacturers wont loan me one to strip down) . If I can get the money I would be interested in the Arturia.
yeah the naked KORG Minilogue vid! :)
very nice Markus
+RetroSound Thank You. It sure does sound good. sorry I did not show off many of the sounds but thats for your channel :-). Best wishes from Markus
+markusfuller I take the items after your vid and make a demo ;)
love your vids!
If we lived close I would certainly send my items over to you for better demo's but then I would need to take your gear apart and that would keep me busy for years LOL :-)
"close to Magnetic Fields" LOL
That was a bit nerdy and at the same time perfect. Yeah, I like that sort of jokes.
I''m really glad to hear it's built with good quality components!! I have two Monologues and a Minilogue
I own one of these and they are a fantastic synth. Normally when I mess with synths it takes me a while to put together a sound I like but with this little guy great sounds just keep popping out.
As a complete newbie to modern electronics (I last built a terrible oscillator circuit on a breadboard in the 80s), do the oscillators, envelopes, filters, and amps happen in the small ICs you couldn't identify? Given that you mainly identified what I assume are digital micro controllers, I am wondering where the analog bits are in the design. Are the micro controllers there to send voltages to the analog circuits from memory or from the signals from the pots and switches above?
Great videos.
Board number 666 lumininati confirmed
hi Markus. Thanks for another brilliant teardown vidoe. The build quality certainly inspires confidence, and it seems incredible value for money.
+1VperOctave Thank You. Yes for its cost it certainly looks a good build.
Thanx for the teardown!
It´s like what we gonna be seeing in new synths...rather low end uCs, but many of them, as they are cheaper than a single and obviously more powerful design.
On top of that, it´s modular for the manufacturer. If they want to do an 8-voice device they just need to copy&and paste the layout 8 times, or put one voice on a board and cone that board...
+TubiCal Yes an 8 voice next. I like the sound of that
It should have 10 voices, 10 fingers : )
your review makes buy products thanks in coming days you will be the official reviewer
The monologue is one of the few if not the only quality polyphonic all analog synth that is in a great price range. I love mine. The few bugaboos are no re routing capabilities so no mod matrix besides a slider for cutoff and such. And the slider it self is a silly thing to make cheap on this board but I did the same mode and it seems more stable but def a good buy. Also someone mentioned no sub octave but it does have one in mono mode your same knobby to change the arp patterns and detune becomes your level for your sub octave wave (I believe it's actually a sub of Osc. 1 but could be wrong) so. Also the first one my buddy had when the came out had very snappy envelopes that clicked in a bad way. The updated the firmware and fixed it nicely. But I received mine a month ago and it is def been removed from the newer shipments or just has the latest update. Awesome synth!
This is the first takedown you've done, for a product I was already intending to purchase, and what you found reassured me, like the metal pot posts, for example. Really nice video (I didn't seem to have any problems with resolution, btw.)
+Michael Smith Hi Michael I think the resolution was just youtube processing the video. It all seems OK now.
You've made me want one of these now. The advert I got at the end was: Arturia Drumbrute!!!!!!!! sounds like I need one of those too.
btw the chords u played while it was fast forwarding while u were putting it back together were v nice!
I like the little DIY fix to the pitch bend too! gr8 vid as usual!
+CYPRN Hello I thinkk they were the opening chords to David Bowies space oddity Fmaj7 then Em. I already have people asking if I will to the pitch bend fix for them. but the video shows them how to do it themselves and I guess Korg will implement that in future production hopefully.
Very informative! One thing that seems quite ironic though is that despite this being an analog synth, it has so many processors that it must be more powerful than old supercomputers :p
Yes I often think similar. so much power surely it can do more ?.
I don't think it would be still considered an analog synth though!
Great channel. My new favourite! I have a couple of vintage Urei units that need some servicing and watching your videos is great guidance for troubleshooting.
Thank you very much for that very interesting tear down! Great to hear that you are impressed by the generell build quality & that you get lots of synth for the money.
When I compare my 80ies Juno60 or 70ies Elka X705 with the Minilogue, the electronic is now real mini, although analog.
Looks like It does not matter if 1 or 4 voices, probably 8 voices would have also fitted in the case.
When it is possible to produce a real 4 voice polyphonic analog synth with aluminium, real wood and radio controllers, many knobs, slimkeys & oscilloscope at that price, I wonder where the other competitors in this price-range are ???
+VolcaRock I agree I dont know how Korg are making these things and making any money from them. theres shipping taxes and shop percentage to come out of that end price. still i like the idea of an 8 voice version
Unlike Roland who needed Malekko & other 3rd party, Korg has a developer team with massive experience. They started with Monotron-gadgets followed by Monotribe, MS20mini, Volca-Series, Odyssey and now ML.They make profit on the mass market.
I ask myself what price is 1 voice on the board (just hardware)? about 20$?
Price is 500$ for 4 voice Minilogue
would be 440$ for a 1 voice Minilogue (still good price, but not a no brainer)
But what if they would make an 8 voice?
I am sure we will see a Maxilogue with 8 or even 12 voices on the next NAMM for attractive price.
+VolcaRock I think the competition will be coming thick, soon. Before, or at, NAMM 2017 i think several competitors will announce a counter-move of sorts.
Looking back over the last several years, each year 1 company have had _the_ gamechanger of the year, leaving very obvious traces in the market and the competition in the following year. Ofc it's a circular series of reactions, but a few stand out. And this year i think it will be the Minilogue.
Imho in 2012 it was the Arturia MiniBrute, kickstarting the analogue renaissance, and a subsequent lashings of cheap analogue mono synths, from companies they hadn't touched that market segment for years.
In 2013 i'd argue they took it again with the MicroBrute, pushing the boundaries for cheap analogue, the response to which brought the Volcas among other. The CV-ports also helped bring eurorack into the minds of people that would previously steer clear, and have had a hand in its resurgence.
In 2014 i think it's the Roland System-1, not only did it revitalise hardware VA as a whole, by bringing it closer to the analogue competition. But it reintroduced the notion of polyphony in the lower pricebracket, at that point utterly dominated by analogue monosynths. It _may_ not even be a stretch to think it has something to do with the Minilogue being 4-voice poly. And the ACB technology will yet do more good.
2015 is harder to gauge a single entry pulling more weight than the rest. There's many good contenders from the Prophet-6, over the Roland JD-X's, Boutiques, Yamaha Reface series and ofc the KARP Odyssey. But i think my choice would be the Reface DX, as i think it will be the harbinger of several FM synths to come, perhaps for the 1st time in a long time, even challenge the monopoly of the subtractive synth. Volca FM any1?
Now if people actually read this novel, they're probably thinking something like "what about the MS-20 mini?". The list isn't based off sales numbers, where the MS-20 mini did very well no doubt, probably better than all but perhaps the MicroBrute. However it didn't really bring anything new, and it didn't really change anything, which would be the main requirement for being a gamechanger.
Now with the Minilogue more than likely being this years gamechanger, i predict the following: Novation finally bringing the PolyStation.
Roland have 2 potentially promising venues of retaliation, both the ACB-VA and the analogue from the hybrid JD-X's. Timing wise it's most likely to be a development on the ACB (System-8/10?), but perhaps they'll make a Aira hybrid with both ACB and real analogue? Or take the analogue voiceboard from the JD-XA and put in a smaller knob-ladden keyboard.
Yamaha will no doubt run with a bigger stronger FM synth, probably somewhere between the original DX7 and the Reface DX in terms of size and features, expanding on the interface-improvements with more hands on features to compete with the nice interface of the Minilogue.
Essentially each playing into their own strengths to challenge it on feel, interface and playing-experience, rather than trying to level the playingfield.
Korg was Kickstarter of the analog renaissance for the cheap mass market
with Monotron in 2010 followed by Monotribe in 2011!
And then 2 years later in 2012 Arturia made the Microbrute
And the MS20mini was something new, because before its release
nobody believed that a global player would make a 70ies remake of an analog synth especially at that price!
That was more unbelievable than the ARP Odyssey because it was the first.
There have always been amazing VA synths since at least 10 years , so I would not pay too much attention on them (when talking about anlog)
even when the technique is now better. Analog is a market which survived (like vinyl and tube amps) and the Minilogue
is the gamechanger for budget analog poly.
Musicians who spend 2000$ or more on a synth will do that anyway with or without Minilogue so Prophet06, OB6 are out of competition. A big sucess on the mono market is Mother 32, I do not know any other facebook group which growed so fast! But it’s mono and Rolands Hybrid has a minimal analog section only . Reface and Volca FM, is fine, but other technique.
I am interested what will happen in the budget analog polymarket. Akai was awfully bashed and even with a AX60 remake it will be hard for them. Yes, maybe Novation with Polystation, but Roland will not produce budget analog poly.
I guess THE ONLY real competitor who is actually able to produce at the same cheap price &same quality as Korg will be Behringer/Midas with their 6 voice analog poly with Rolandfilter clone. Coming soon!.
VolcaRock How many products have you seen with any relation or competitive value to the Monotron or Monotribe?
The answer is none. Ergo they didn't start the analogue renaissance. Also it doesn't take 2-3 years in a market as competitive as this for the competition to react. Firmly reflected in my list that showed the emergence of several analogue monosynths within 1 year of the MiniBrutes, and subsequent circles of reaction. Never taking anywhere near 2-3 years.
True the MS-20 mini was the 1st cheap copy of a 70's/80's classic, with no real alterations or improvements. How many have taken that up and followed or copied?
Again the answer is none. There's been several nods at the past, but Korg is still the only to make a largely unaltered copy.
Neither this, nor the KARP, are hardly unbelieveable.
But the KARP atleast brought a different set of waves, it had a bunch of improvements that helped shape the MS-20M and the Minilogue. And the cooperation elements may have had a hand in the Sequential/Oberheim cooperation resulting in the OB-6. But as i said, there were less of an obvious winner in 2015, the Reface DX being the closest to a gamechanger imo.
Roland is indeed unlikely to do a cheap dedicated analogue, but never the less did their ACB tech influence the market overall. And while it'll never outdo or replace proper analogue on its own battleground, digital has its own number of strengths that become increasingly appealing, the closer it comes to analogue in sound and feeling. So to assume it won't influence or change the market simply because it's not true analogue, is a big mistake, and quite frankly a bit narrowminded.
Like i said before, it's not a stretch of imagination to think the Minilogue is Korgs response to the System-1, effectively saying "we can do 4 voice poly too, but we've outdone you with it being a proper analogue".
The high end market, more often than not, stroll at its own pace, doing its own thing, and only slightly influenced by competition. The customers go for a particular sound and feeling, geared towards high end _instruments_. While some innovations and ideas filter down to the cheaper market, it's often a slow evolution over several generations, compared to the fastpaced changes and experiments going on in the cheaper mass market.
Again it's narrowminded to think just because the competitions reaction to the Minilogue won't necessarily be analogue, that it won't affect the market and pose a credible threat to the Minilogues sales (i still think it'll be 1 of the all time best selling synths).
There are afterall people, particularly the growing number bored with all the analogue monosynths, that will see Rolands VA/Hybrids as a viable alternative, or going for the difference in FM synthesis, we're likely to see more of from Yamaha. Plenty of people around that don't care whether a synth is analogue or digital.
And to discount that any company could bring out a similarly cheap analogue poly, would also be a mistake. Just see how surprising it was this time around. But there's nothing to stop a number of big players doing the same out of the blue.
Except if you look at the likes of the DSI Tetra, it won't necessarily be out of the blue.
Fantastic work as always Markus! I was looking forward to this...Very happy to see that it's quite good quality under the hood!
And I liked the Magnetic Fields joke...
+mootbooxle ThankYou very much
I was waiting for this!
Some people were wondering how long it would take for a teardown of this, and I was hoping it would come from you first :)
+inthefade ThankYou I hope you enjoyed it as much as I did. Best wishes from Markus
Very nice video. Just bought one and it's great to see such a nice piece of engineering. One tip: put some additional heatshrink on the spring levers and you'd get rid of the clicking sound completely.
so you put the heatshrink the way Markus did in this video and you additionally "covered" the two sides of the spring in heatshrink? DId you make any pictures that i can see somehow? Is it enough to remove the Aluminum lid or do i have to go deeper (like removing more than the Aluminum plate) ?
ha ha..me too..i remember when i was 12 years old and taking my dad's philips reel/reel recorder apart.. out of pure curiosity, then put it in a box back on top of his wardrobe :-) i love seeing how stuff works..
Awesome Markus u was waiting for this tear down, the built quality of the interface very good, above this price point, nice to see the pots and switches can take abuse and can get replaced if needed
+Walter Galindo Yes it looks easy enough to replace them if needed. though i think they will last many years
Thank you Markus, great tear down again. I believe that Dave Smith opted for opto-isolators( see how I played with words there! ) to eliminate mains loop hum. My brother has a mains loop hum on his set up, so I will tell him to disconnect his usb stuff 1st to isolate the cause.
+Anoop Sahal I guess Dave learned from the Pro One which is prone to humming :)
2:48 Nice album Markus! I visited 2 Jean Michel concerts here in the Netherlands. Nice channel also, I subscribed!
Nice teardown! Do you know if the Delay circuit is pure analog, using "Bucket Brigade" delay circuit?
nice one...was waiting for your tear down video to see the build quality...looks well spece'd
+cresshead Thank You
When you think about it, it is really amazing that Korg can produce the Minilogue and sell it for under $500.00. I mean, so many parts involved. I look forward to the day, if that day comes, that Korg produces a six or eight voice Prologue or Maxilogue that has 61 full sized keys :)
Amazing! It's my next synth and I was afraid about the pots, a point that took me some problems in anothers synths like the Microkorg (that if any pot was fail, all the functions on the synth came on aleatory value changes and a pot replace were involve a real problem because it's not a simple welder-and-ready work).
After your video, I'm more calm! :) Greetings from Argentina
Just installed a piece of heat shrink around the spring post on my Minilogue! Great idea! Also lubed the spring before re- installing it. TBH, I was just looking for an excuse to void the warranty. It was worth it
Excellent video! I plan to get one of these very soon. Thanks for posting.
Thanks for the neat info/teardown.
I'am looking to buy it or maybe saving (lot)more to get OB6 (bloody head scratching)!
+Jetset Willy OOH I too like the OB-6 . I cannot persuade you either way as I guess the OB-6 is going to sound excellent (as does the minilogue)
+markusfuller The OB-6 definitely kills the Minilogue, as far as sound design. Stereo synths always win, in my books.
But who can afford the damn thing?!
But the Minilogue is wonderful, as long as you can get over the now infamous EG clicks. I hope I can pick one up some time this year.
I would love the OB-6 but then I would love to every synth which is just not going to happen. do you know what the cost will be for the OB-6 ?.
+markusfuller Local Toronto shop is taking pre-orders for $4,340 Cdn which would be around $3,000 USD
+inthefade i will afford that sucka. selling gear and part of my arm now.. ;)
Awesome video Markus! Very nice explanation. Really enjoyed it.
My slider is not working properly. When pitch is assigned, it oscillates rather random and it suddenly stops from reacting to any movement. Mechanics seem fine so thinking its software probably.
Do you know how I may be able to disable the slider either hardware or software? The only work around is to assign it to a delay parameter and disable the delay but it is really annoying.
Thank you sir in advance.
Just got one of these, and the final a# key doesn’t work on lighter presses. Might have to tear it open and clean the contact. Do you have to take off all the buttons to remove the top? Also, great video!
Great video, thanks. The build quality seems really good, I'm just wondering if the black bottom plate of the synth is made of metal or plastic.
3:00 probably to keep the top panel from getting bent upward during shipping, especially at the front edge where there are no screws holding it down.
You make it look so easy with your FWD teardown....:-) In real life i tried it and really it felt longer than in the video....:-) Btw about the rattle switch. I did what you shown and took it further. I put some heat shrink tubing on the springs on both sides and also the same principle i did on the little white slider-knob that the spring is keeping in place. I made a thin little cylinder formed ring made of fabric tape that i secured with a drop of glue and covered the surface of the white slider plastic knob-slider where the two spring arms touch the white plastic . Not it sounds like an expensive synth :-)
Btw out of 1000+ Thumbs up, 9 Thumbs down on a teardown video that is for free.... That shows us that at least 0,9% of the population will never be happy. It`s genetics baby
Glad to see they for the most part seem to have avoided the mechanical rotary encoders here. I've had plenty of problems with those on other gear, getting noisy over time. The mechanical ones are really cheap, and while they may be gold plated, the plating apparently wears and/or it oxidizes to the point where the connection goes bad in record time. The Korg Electribes and the Electron gear have a lot of flakiness problems with them. There are actually some inexpensive optical rotary encoders available, but they require power for the LED, and it seems all to often the designers don't use them.
Hi, very interesting video, thank you! What are the programming ports for, exactly? And how can you use them?
Great video and very informative. This is the first video that has excised me of that inherent fear all users have as to the internal nature of these beautiful tools. Thank you.
+Taren McCallan-Moore Thank You very much. I am completely independent and receive nothing to say things are good. most items are what I have purchased myself and if they do look well made that is my unbiased true opinion. I was looking forward to opening this up and truly thought there would be cost saving going on inside especially for the price of this synth but was real pleased to see that Korg had genuinely made a good value product in the minilogue. This is a synth I will keep for life now I am getting to play around with it, it does sound really good.
Thank you for your reply Markus, your insight is very useful and your enthusiasm an inspiring pleasure. I wonder if I might tap your knowledge if I may? I've just purchased a Roland CR-5000 and the question that I have is regards the fact that it's ac100v. Can I use a standard 13amp 250v adapter or do I need some kind of transformer? I would appreciate any thoughts you have about this. One final question, regards your repair service, how might I find you for future reference? I'm in the south of England, Kent. All the best.
Hello Taren, normally You must purchase a step down transformer. if you use a plug adaptor you will still get 250volts to your CR-5000. I am not 100% sure but if you know someone who will open it up the power supply is steel cased top right and there may be a way to change the Taps on the transformer to allow it to work with 250volts. that would mean unsoldering certain wires from the transformer and attaching the correct ones for 250volt operation. if this option is not on the transformer then you need to purchase a step down transformer that you plug your 250volts into and get 100volts out. they can be bought from places like Maplins electronics or off Amazon etc. Good luck :-)
Very much appreciated help Marcus, thank you. Off to Maplins then. All the best. :-)
hi great vídeo, im impressed of your knowledge. I've a minilogue and have quite an annoying background noise when there is no sound playing. tried the korg ms 20 mini to check if it was normal, but the ms 20 did not have any kind of background noise (as I was expecting). could my minilogue have some kind of fault? I'll really appreciate some help with this issue. many thanks
Good one Markus!
I was wondering about the dimensions of the boards, the four plus one processor one in particular.
I would fully expect a eurorack keyboardless follow on, so wonder if this pcb woukld fit? The reuse seems a no-brainer in the design, like with the Roland System 1 and then the System 1M.
Perhaps that also explain some of the unpopulated components, audio paths, or CV in or outs, etc?
Me thinks i'll wait a few months, to see what might appear, for me a modular of this is even better.
+Jukka's Channel Thats a good thought. they could be put into a rack or eurorack separately ?. Hmm me thinks you may be onto something here.
Very informative, thanks! I'm just wondering whether you found a dedicated delay section. From some of the demos and the mention of the noisy delay, I wondered whether it might've been a PT2399, as used (I think) in the Monotron Delay and a bunch of cheap pedals etc. Notoriously noisy and quirky, but with their own charm and an almost low-fi tape echo sound.
+voltlife Hello I am not using the onboard Delay I have been experimenting with the output going through chorus - delays - reverbs - phasers etc etc and its starting to sound like a completely different synth.
whats the black plastic frame/cladding for? to prevent strain on the pots when we have our "ROUGH KNOB ORGIES" ?
Amazing teardown. I have a minilogue xd and I have an issue with the first 2 octaves of the black keys. It seems like they need more pressure to work than the last octave. They still have velocity so that's not the issue, but I was wondering if you managed to figure out how to change the tension/trigger point of they keys on the keybed since I didn't see a key disassembly.
In case anyone is wondering. The keybed is the same as the one on the Minilogue from what I could see. No issues with the switches or keys, but there's this felt pad that the keys bottom out on that's a tad too tall on one side of my keyboard. I'd reckon that with time this will wear in and become proper. So the fix is just to play a lot.
Love the video. I always want to know what the insides of my electronics look like, but don't want to risk disassembling them just for curiosity's sake.
Thanks for making this teardown video, it came really handy. The program knob shaft on my minilogue has broken and I'll be replacing it soon, do you happen to know what kind of potentiometer it is? Might be a rotary encoder but I'm not sure.
Im sorry I do not know the exact version that korg is using and there are many different types. best to look at the original and see if there are any words or numbers on there that may help in searching for the correct version. I hope you manage to get it repaired. best wishes.
Another great teardown. Thanks Markus. 👍
+Dave Hanson Thanks Dave
Hey Mark I wanted to know if you can make some videos on the Korg Volca series (I am a new proud owner of the Keys and Bass!) and to see what are some of the hackle components that each device is capable of? Thank you!
I think the oscilloscope is even generated by the STM32 processor on the switchboard. It has enough power to do that.
+Chip Guy Vids Yes I guess you are right there, plenty of processing power for a simple scope.
Thank for showing the inside of the Minilogue. Great video, as always. They are a little bit expensive, but have you ever opened something from Waldorf? My Streichfett says it was made in Germany (I think they all say that), but I wonder if it was only the final assembly, or the whole thing.
Cheers.
+Philip+ Hi Philip I have the Streichfett waiting for the teardown which I will do soon.
Great! The Streichfett is all digital, so I'm betting it will revolve around only one big IC at the centre... I'm sure it will be a great video.
Cheers :)
thank you markus for the look inside :)
and of course for this great channel!
+Adriano Mono Thank You Adriano
i was waiting for this...thank you markus !! keep doing ...
+tiboliebymusic Thank You
Excellent video as always Markus! Thank you very much, you really are doing a service to the synth community.
Quick question! While you were on that main panel board, did you notice what size the LEDs are? I want to do a color mod to mine and I'm assuming they're 0805, but i can't tell from any pics (or find a schematic). Thanks in advance for the reply!
Excellent video as usual Mark! The only mistake I could find was that you said the USB port carries Audio. It only carries MIDI. Must have been a force of habit from the Roland synths!
+adriansmithmusic Yes I think I will have to go and place a message on that. dont know what I was thinking there.
Hi Markus, thanks again for an awesome video. The Kylie Minogue (as I like to call it) is definitely an attractive synth. Would be interested to know if those arm processors are responsible for the generation of the waveforms (does that then contest what we would consider to be analog?)
+fkthewhat Hmm I would love to know more about the actual employment of the processors within the Kylie myself.
I really like the Minilogue, and now we know it's put together nicely. The only thing it's missing, in my opinion, is a sub oscillator. Would reallly like a sub on this to fill it out as a complete analog synth.
Matthew Maneri sub oscillators were not on the ob8, prophet-5, minimoog, etc. are those not "complete" analog synths??
Of course they're complete analog synths. The obvious reasons why have nothing to do with not having a sub oscillator.. the OB8 had 8 voice, the prophet-5 had 5 voices, the minimoog had 3. Granted, they were 2 grand more money for those extra voices, but I'm not asking for another complete voice, just a sub osc.. which aren't that expensive or involved to add on. I'd pay another 100 bucks if the Minilogue had a sub to go with the 2 VCOs.
I am asking for at least two more voices, 61 keys, and yes... a sub oscillator. Should still be under 1,000.00.
Matthew Maneri but it does have a sub if you set the VCOs to different octaves...
It has a sub osc in Mono mode
I was thinking about rehousing my minilogue into a rack unit. Would the synth work without the board that has the pot's, and the keybed? I was planning to use a computer editor for patch programming and switching.
Hi Markus, the oled screen on mine doesn’t work at all and I’m thinking of ordering from US. I don’t have the monologue to hand but remember the screws holding the top plate on we’re weird. Do they require an Allen key or is it something else I need ?
I'm considering purchasing one of these for my first hardware synthesizer and I have a question about using it with Reason Essentials. I see that it has a USB type B plug which is the same as my Novation Launchkey 49 Mk2. If I were to plug this into my computer, would I be able to control it with my Novation product? I really enjoy it and would prefer to keep as my main controller! I also would like to know how I would go about getting the audio into my DAW, would it simply be a matter of using a 3.5mm jack adapter to a microphone port?
Thank you!
--David.
P.S I do not have an audio interface.
+venomblademedia Hello The USB on this only sends midi data to and from the PC, It does not send any audio data. you will need to have an audio input on your PC or some way of grabbing audio to USB. many modern PC have a mic input that is also a stereo input but dont take my word for that as I do not know the PC you are using. you will have to check if your PC has a stereo line in. or if the Mic socket doubles up as a line input. remember the minilogue is only Mono not stereo though the headphone output will split a mono output to 2 channels.
I dare say, it is perfect.
The Perfect synth
Aww man i am stoked about this tear down. Great show.
+my4trackmachine Thank You very much
Excellent video as always. Markus, what is the bracelet on your right hand? Is it for protecting against an electric shock or something else?
Hello the bracelet is connected to the Earth/Ground . it is to prevent electrostatic discharge that can sometimes corrupt microchips. its just a precaution. many thanks from markus
Ah, got it. Thanks for the answer too, Markus.
excellent teardown as usual - Thank you.
I just bought on e of these second hand and the slider doesn't work at all although its spring\action seems to be ok (it moves back and forth like it should). Do you recall\think that it could have popped off the interior mount (the one you put shrinkwrap around)? ie is there clearance enough for that to happen?
do you have a repair manual for this? I was hoping to see the wiring of the OLED/Oscilloscope as I wanted to replace one.
Useful information about the mod slider spring - thanks!
+MusicInclusive Thank you
...close to Magnetic Fields.
LOL good one!
This is a good video, thanks.
Best channel on youtube!
+JD73's World ThankYou very much :-)
Excellent video, I enjoyed it a lot! Thank you!
I definitely feel the same way about the construction of the slider when I got mine :( I'd much rather have a classic mod wheel. You don't get nearly as much control and you have to hold it down so you can't play with both hands if you want full modulation on the fly. All in all though, fantastic synth for the price. I love mine.
hi Markus! how do you think they did to reach that low price? Are electronics cheaper now than back in the days? thank you for all your videos, Im studing electronics and Im learning a lot seeing all that synths inside
yeah the components are really cheap now, a reel of 5000 resistors is like $12.00, and it only takes maybe 15 minutes to build the board on a Smt machine. But the price has a lot to do with the company's overhead. So Korg may be in a better position than smaller companies like Dave Smith Instruments.
+Keepin' Soul Hi I agree with friendofCHAKA , the components are quite cheap and I uess the biggest cost is research and development. also its sometimes a good marketing move to make a little bit of profit on a lot of items than to sell just a few at a high profit margin, I think Korg are well placed to gamble on selling lots for lower prices. There is a shop here in brighton that will fit a new battery in your watch and charge you £1 all in (he is always busy) then there is H-Samuels the jewellers who will sell the same battery from the same manufacturer for £12.99 and say with a smile they will fit it free. guess who sells the most batteries. and consider they only cost £0.08 each to buy in bulk.
+markusfuller thank you both for the reply. Check Attack Magazine, Korg engineers talk about this video! One engineer talks about how using the ARM microprocessors they have cut some costs
Awesome stuff, thanks for doing this!
I gave it a thumbs up just for the magnetic fields cd, interesting video again anyway.
The "direct sunlight" warning is because the aluminum absorbs and transfers heat very well, and fully analogue synthesizers can be detuned if their temperature changes too much. Oddly, though, most of the complaints I've seen about the minilogue detuning have been because of excessive cold.
Markus, can you do a teardown of the Korg Monologue? shouldn't be too different but I'm very curious
Your channel is simply amazing!
thanks a lot for your very explicative work!!!!
+marcoballa Thank You
Thank you for the great teardown video, Markus! This seems pretty easy to mod to remove the awful "slim" keys and make a module version out of, wouldn't you say? Take apart, saw off the bottom bit of the front panel and plastic case, and put a nice wood plate in front to close it up... I didn't see anything in the teardown that would prevent that. What do you think?
Ever since I heard that korg was making a 4 voice analog poly I wanted to see what a modern day analog poly looks like, thanks for showing us this fine synth. What got me excited from korg though is the volca FM, now that I want
+joeboygsxr the Volca FM looks interesting . I may just try and get my hands on one of those.
It is digital unlike the rest of the volca series excluding the sample but would still be very interesting to see what chips they are using.mi love the fact that you can load up your old sysex patches from the dx7
+markusfuller have you got any of the volca said Markus? I have the beats and the bass, if so have you done the snare modification/fix for the snare?
+joeboygsxr Hi I have no volca's I like them and am intersted in them very much but just have not yet got around to buying one yet. I will do one day as I think they are brilliant devices.
Wondering about the one encoder pot, pretty common part or something I should buy a back up of? Looks like the regular pots are easy to source later.
Im pretty sure it is a common part and would possibly be sourced in years to come. (well I hope so anyway)
Thanks Markus, big fan of your channel! Keep up the good work man! I don't know if you've seen it, but the designer(Tats) references this/your video in this article, pretty cool:)! :
www.attackmagazine.com/features/long-read/the-democratisation-of-synthesis-korg-designers-on-the-making-of-the-minilogue/
purpleibby Hi yes I have read that interview with Tats , he is a brilliant guy and I think there is going to be more incredible music gear coming from the mind of this inventor over the coming years.
Great video, thank you!
+Akos Janca Thank You Akos
Would love to see if the Monologue is the same build quality...
I'm going to get this synth when I can afford it, no doubt.
Also, I'm surprised you haven't done a teardown of the MS-20 mini yet. Do you own one?
I couldn't tell from the video how so many potentiometers were handled by the UI. Are there any extra ADC chips or some analog signal multiplexers or such on the PCB? Are any of the signals filtered before going into the ADC?
+krakulandia Hello from what I remember the top control section had one ARM chip and a couple of smaller chips but I think the pot controls was maybe multiplexed by the arm processor where it would check the resistances of all the pots one at a time but at very high speeds. Thats just a shot in the dark but may be how its able to read so many pots.
+markusfuller Ok, thanks!
That was great to see Markus, thank you!
+mCKENIC Thankyou mCKENIC
That wobbly slider really is an issue... on my Minilogue, it doesn't always come back to 0... stops at 2% sometimes and I have to manually zero it. But thanks to this video, I know how to fix it. Just need to get my hands on some heat shrink in the right size...
