    Very nice of you to show the output of the gate on your oscilloscope. I am refurbishing an old Elektor Formant synthesizer and the gate is not working at the moment. I am troubleshooting it and i first thought the gate output was looking strange from the SQ-1. But seeing as your output is the same it is probably working as intended.

    For Akai MPC Live mk1 users wanting to work with modular... I tested the SQ-1 MIDI to CV with my Akai MPC One (latest firmware) via USB-MIDI. The One has CV outs but I tested the MIDI to CV anyway. It works well but you have to set the MPC to not send sync otherwise pressing Play on the One will start the SQ-1 sequence which overrides the CV conversion.
    Using it as a sequencer slaved to the MPC One, I did have to set the sequence step resolution on the SQ-1.

    Nice video, sir! I'd not really noticed this box, until now; the breakdown of the device, and general price points of some of the key internal components were fascinating.
    It seems that everyone is wanting you to build something. If you had the time, and support, I'd vote for a filter box. 'Marcus Fuller's Fuller Filter.'

    I think Korg doesn't necessarily wants to make money on the SQ-1, for it mainly enhances the usability of other Korg synths, like the MS-20, with which it was sold in a package, and the Volca's. The profit might come from increased sales of bigger Korgs thanks to the SQ-1's. Just a thought.

    I have one, it's nice but there is no Midi clock in and it won't properly respond as a slave device and start playing in sync/sending Midi out unfortunately . . . The only way I've found it to partly behave as a slave is by hooking up a Korg Volca to the Midi and then running a sync cable to the SQ-1

  • @Philipplus
    @Philipplus 8 лет назад

    I brought my SQ-1 in late December: it was great to see how this thing is assembled. I'm guessing Korg has gone for a price that would draw the most people into buying it. This instrument does not make sound on its own, and that might be a deterrent for some. My guess is that if the SQ-1 was more expensive (lets say about 200-250£), less people would be willing to buy it even if it had more features... but on the other hand, there are the beatsteps...

    • @markusfuller
      @markusfuller  8 лет назад +1

      +Philip+ Yes Im looking forward to getting the beatstep one day as that looks very interesting. But I have to watch the funds as i have spent way too much too quickly. plus I want the matrixbrute also.

    • @Philipplus
      @Philipplus 8 лет назад

      +markusfuller I fully understand you... it is only a small step between having a synth collection to start synth hoarding. ;)
      I found that the control software for the beatstep can not run under linux (not even using a virtual Windows machine), which is a deal breaker for me... on the plus side, I don't have to by the Beatstep Pro now! :D
      As for the matrixbrute: it's simply too big for the space I have! I like the variety of modulation routing it offers, but I'll probably be content with the Pulse 2. Nevertheless, I look forward to see your "dissection" of the Brute in the future: it is the only way to really see the build quality of the instrument, but I think you are the only person on the internet with the right combination of know-how, interest (and courage) for that endeavour ;) :P
      Cheers

  • @kassutronics
    @kassutronics 8 лет назад

    I suppose what helps keeping the price low is that they use a lot of components the same as in the volcas (the transparent potentiometers and button caps at least), so SQ-1 can benefit from the high-volume volca production

      @markusfuller  8 лет назад +1

    Did you try changing the Duty knob when it was hooked up to the 'scope? I imagine it just makes the gate signal wider and narrower, right? It also has an effect over the midi out, so it's probably extending the time between the note on and the note off command, right? (I don't know a whole bunch about midi.) Cheers!

    Great video Markus. I have to ask, to the right of that 4mhz crystal looked to be solder points. Perhaps serial or JTAG? I wanted to ask if you've had much experience with using these for repair, hacking or general curiosity? I wanted to share with you that just recently I watched some videos about how you can use a USB-Serial cable to connect to wifi hardware and re-flash the operating system with a small distro of linux (open-wrt for example.) I had an old router lying around and with too much coffee and soldering skills not exercised since high school, I managed solder some wires on to the pads (which are very, very tiny and close together in my experience) I was blown away though at the reward... connecting those wires to a USB-serial device I had bought long ago and getting to see and access an operating system that otherwise wasn't available to me... I haven't tried to install that alternative operating system just yet, but I can only imagine that quite a lot of the modern synths you've opened probably have something similar? I understand a lot of stuff you open is for clients, but perhaps for other things it would be great to see what might show up if theres an interface available...

    • @markusfuller
      @markusfuller  8 лет назад

      +fkthewhat Hello Yes you are correct that is a programming interface for the processor. I think at production there is just a small connector that touches the pads and the holes are just to line it correctly. I have not had this very long and do not have a lot of knowledge for hacking it (yet). I think it will more likely be Jtag . Many thanks form Markus

    Hi markus. Thanks for sharing this video. I would like to know why I hear ground noise after connecting my sq1 via usb. My setup would be cv and gate connected to an ms20 and usb to my macbook. As soon as I plug the usb I start to hear noise. Thanks!

    • @markusfuller
      @markusfuller  8 лет назад

      +Firdous E Bareen to be honest I have not even tried the USB yet. I think the outer casing of USB is grounded by your pc and may (just may) be connected to the ground of the jacks and therefore a signal is being picked up off the USB or PC and adding it to your ground of the jacks then into your sound modules/synths almost like an imbalance on the ground which is why some audio equiptment has a ground lift switch. does it make the noise if you run it from batteries without the USB connected ?.

    • @nonfungibletrauma
      @nonfungibletrauma 8 лет назад

      +markusfuller Is there a way to isolate the jacks or something? The noise does not appear when I run the SQ1 with batteries. Thanks for your response

    • @markusfuller
      @markusfuller  8 лет назад

      Hello you cannot isolate the jacks as it needs the ground because thats like the negative of the voltage required to output its voltage. it sounds like the earth from your USB is mismatched with the earth on your synth/sound device and the SQ-1 is just connecting that as that is in the middle of the two. you could try disconnecting the earth lead on your synth though I would strongly not advise doing that. if you are using many mains extension leads you could be mismatching the earth or neutral distances and that can sometimes create hums. try plugging your pc and sound source/synth into 2 sockets on the same extension or power outlet, also bear in mind that if you have an amp or powered speakers plugged in at the other end of the room that can also introduce noise.. Its a problem I have heard before when I use to setup equipment for stage. all my music gear PC mixer speakers and synths come from one filtered socket and there is no hum at all unless i start using old organs in the setup which feedback hum into the loop again. what are you using to make the sound ?.

    • @markusfuller
      @markusfuller  7 лет назад +1

      Jarrod Estes Jarrod Estes Hello Jarrod, Im not sure how you want to use it, im guessing the midi out could clock the MPC while the gate or sync out could clock the mother32 (that im not sure of though) but you would be controlling the tempo only from the Korg SQ1 (thats if it all works like that) . However if the MPC is on USB to pc then you would USB the SQ1 and get a gate trigger or clock to try and trigger the mother 32 or the MIDI out to midi in of the mother32. but I have never tried this and have never had the mother32 so its just me giving a wild guess.

    In regards to profit, it is not uncommon for larger companies, to take between 3-7 times the manufacturing cost of a product in price when they sell off to retail.
    You'd be surprices how cheaply they can manufacture electronics. So Korg will make a decent profit off of this, otherwise they would not bother wasting their time on the product :)

I used to have a $100 MIDI keyboard for iPad, but frankly I am glad I sold both the iPad and the keyboard. I'll keep the other sub $100 items that I mentioned.

    i bought one of these korg sequencers and it did not work properly, the ribbon cables had been soldered in poorly so the LED's would not come on, the quality of the product was pretty poor and more like a toy than a proper musical instrument. ive also complained to Korg but they dont give a damn about their customers, on the whole a very annoying experience. if you look on their forums theres a lot of complaints about similar problems, leds not working, buttons failing and in general just bad quality control. i would avoid their stuff like the plague now...
