- Today we are looking at the Matrix Mixer! They are great devices that offer useful basic utilitarian functions, but also open up creative routing within the modular. In this video I quickly show how a Matrix Mixer works, and then I dive into four basic concepts: Modulation routing. Audio routing. Sequencing. And feedback.

didn't think I'd need one, but doing feedback patches taught me. that's why I started to build myself a vcamatrix.
Ah cool! VCA matrix for sure adds a lot of possibilities to the table, now I need to do another video :) Enjoy the build!
Nice one! Really appreciate the thoughtful demonstrations and animation describing how it works (Matrix mixing isn't always an easy concept to grok)
Glad you like it! And agree. If you know, you know. But if the concept is new a little demonstration can help :) Cheers!
I had no idea I might 'need' a matrix mixer one day, and now it goes on the wishlist. Thanks for your help (in getting rid of my savings lol).
Sorry about that! Haha :)
Superb video, and yes, please come back to feedback in the future!
Glad you liked it! And then I'll put it on my list :) I borrowed this module, and had to finish up. The video could be a lot longer, but will gladly come back to it. All the best!
Great video again.
I loved the part where you went into feedback. It’s such an interesting sound when kept in check.
Glad you enjoyed it! And agree, it's fairly easy to do so this way, and nice to have these different 'flavors' of feedback all close to each other :)
This might be the best modular tutorial I've seen in a very long time. Thanks for your creative and methodical approach!
Thank you very much! Reading these kind of comments make it worth it :) All the best!
I love the result of the 4 oscillators droning at 8:10 and the feedback patch as well ;)
Thanks, glad you liked it! I didn't had to much time for this video and had so much other ideas, so just had to pick a few to illustrate the concepts :)
Why is it that whatever module I look at, I immediately think, I really need two of those for flexibility😂 best modular channel on RUclips by a mile🙏🏻
Glad you like my work, that's great to hear! But hope I mostly inform, and not fire up to much GAS, that's a danger I guess :)
By far you're the best Tips & Tutorial 'tuber' on the market. Really enjoying those.
That's nice to hear, glad you're enjoying my videos :) Cheers!
9:19 fucking insane sounds man, awesome stuff
Glad you liked it, cheers! :)
Love the feedback possibilities of matrix mixers and would love to see your take on feedback patching.
Thanks! And hope I can get around to that sometime soon, it's on my list!
I appreciate the little shadow you put on the overlay going into the jack. Its the little things!
Glad you liked it!
Wow it’s a couple of videos i watch of yours
You always explain so clearly and have a knack for simplifying complex concepts and transferring them into Comprehensible and digestible bites
Infinite Thank You’s
Glad you like them! That makes it worth it :)
thank you so much Monotrail
You're welcome!
Very creative, as always. Thanks
Glad you like it, cheers!
really love your videos man! such good detail and time put into them
Glad you like them! All the best :)
that's some quality content right there. thanks for the great ideas!
I appreciate that, thanks for letting me know! Cheers :)
This video was incredibly useful and inspiring! Thank you!
Glad it was helpful! Cheers :)
Splendid demonstration!
Glad you liked it! And nice to see you around here, hope you're well :)
That’s an excellent video demonstration. Bravo!!!
Thank you very much! Cheers :)
This was very inspirational and educational!!
Thank you! Glad to hear you liked it. Cheers!
best tutorial for such an overlooked module thanks!!
Glad it was helpful!
!! I need to get one of these. This is the most excited I’ve ever been over a doepfer module lol
Hahaha, sorry for causing gas :)
Excellent! Thank you!
You are welcome!
One other possible use is CV ducking. So amplitude CV such as envelopes for three different voices to inputs 2, 3 & 4. Then the envelope from a kick drum, (or whatever) to input 1 set to bipolar and turned to an inverted position (or via an inverter for a matrix mixer that isn't bipolar). Then the CV for the kick reduces the amplitude of the other voices.
I also had another sequencer idea while watching this :)
Set the first three rows as a sequencer, so 12 steps max. With a 3way sequential switch or CV sequence (I sometimes use the gate output expander A-161, or Ladik 'outs' expander for the SEQ-8))
Then a divided down sequential switch to route the column outputs.
Now I can put some arbitrary CV into that 4th input to independently transpose the individual columns, either manually, or with another sequencer, or S&H LFO... so now I have a triplet (or 6:8? or 12/8(?)) feel with a way to modulate the individual triplets as units
(This is similar to something I tried recently using the first three full columns as sequencer, and the last as a set of values that can be sent to a comparator or VC switch to manipulate the routing of envelopes or audio per note in a way that is repeated par 4 note column... worked pretty well)
Gonna go and try that out :)
Hey, thanks for sharing! That ducking trick is excellent! I often use an inverted envelope on VCAs for that, but mixing the ducking envelope in with the positive ones is a solid ideas :)
Sequencer trick as well. I like that you start to see more ideas as you stare at it for some time. Cheers!
Yeah you can basically create a Tiptop Z8000 using an A-138 and two A-151’s :)
To this point, I had no idea of any use cases for matrix mixers, nice video!
Glad I could help! And these are just some starting points ;)
Excellent tutorial. As always, an intelligent video.💡🎵🎛👏🏽💥❗
Glad you liked it, thanks for watching these :)
Tremendous - This video inspired me to get my hands on my own Matrix mixer - Looking forward to trying out some of these patches in my own system. Sincere thank you for the inspiration!
That's nice to hear! And you're welcome, enjoy the module! :)
Thanks for this!
You're welcome!
Nice job! Really useful channel
Glad you think so! And thanks for watching :)
O M G
I never considered matrix mixers. This video is like when I finally understood Maths. Now I need one!
Hey, happy to shine some light on the matter! Cheers :)
Wow!! What an absolutely WONDERFUL video!! Thanks so much for sharing your knowledge! Refreshing, powerful, truly fantastic! God bless you!!
Glad you enjoyed it! All the best to you :)
Great video again. I had exactly the audio routing example with 3 send fx plus the dry channel on my last BMS live set. Worked great and provided massive flexibility to my core sounds. I will try the CV/modulation mixing in my next patch!
Glad you liked it! And nice you're using one live! It's a big module, but indeed I can be a core sound sculpting/evolving tool in performances. Still like to hear it soon! :)
Thanks for this! You have an excellent channel.
Glad you enjoy it! Thanks for watching :)
thanks MTT your teaching is very good and the ideas for experimental patches are very clear with the diagrams / at now alrready sound a patch in my rack and is a new for me thanks again for your channel.
Great to hear you get some use out of it! Enjoy the experiments. Cheers :)
Thank you for this excellent explanation of what, in the surface, looks a little daunting ;)
Glad it was helpful! All the best :)
Thank you so very much for this.
You're welcome!
really nice!
Thank you! Cheers!
Yessss I haven't watched it yet but I'm already excited. I just placed an order for a matrix mixer and I'm sure this is gonna be a great watch!
Haha, that puts some pressure! Cheers :)
Super cool! Matrix Mixers can be so creative!!!
Excellent!
Thank you! Cheers!
thank you!! mine is on order :)
You're welcome! And enjoy the module :)
Great vid
Thanks!
I don´t think there is anyone on YT who can explain this stuff better than you! Which leads me to the conclusion that I must be pretty stupid, because sometimes I still don´t get it :D
First, of that's nice to hear, thank you! But that means I should be doing a better job! Feel free to ask if you have questions :)
Well look at you Mister Matrix Mixer Master!
Mister Matrix Mixer Master, ill take that :)
@@MonotrailTechTalk Ha I just wanted to say Mister Matrix Mixer Master!
In my Quad VCLFO/VCO video I use the matrix mixer too because they work so well together.
Excellent! Sounds like a good plan :)
These videos are very clear and useful, thanks! How about something on Precision Adders like the Doepfer A-185-2? They seem to be very useful for creating melodies.
Glad you like them! That's interesting indeed. I have a bit of a list of core Doepfer modules/functions I'm still interested to cover, but will add it to the list :)
awesome! I sub'd! love your channel.
Thank you very much! Cheers :)
Using the Mixer itself as an Instrument, Loike it, got my mind turning Circles as to possibilities like sending outs on feedback circuit of Delay, Reverb back through a Delay ,Reverb on the inputs of Mixer or any variation of this, fantastic insights, thank you👍🇬🇧🕸🔱⚡️🌀🆒🎶🎶🎶🎶🌟🌟🌟
Glad you liked it! Wanted to include a feedback patch there, but think it deserves more time. Indeed there are a lot of ways to have fun with feedback patches!
you did it! haha i asked you for this on reddit like a year ago
Hahaha, sorry for the delay! Cheers :)
superkewl Explanation as well, btw: I have the Erica Synths Matrix Mixer, for positive & negative Feedback Surfing with Xtra-Controll the Timbre/Toneshaping ( mostly MI Shelves Clone & Tronix Audio Mimic) - refeeding the Feedback Madness :DD
Glad you like it! And nice, that sounds like a lot of fun!
great one. I have an a-138m and have not given CV mixing enough attention.
Nice, glad to add some ideas :)
Great explanation as always! What‘s the wavetable oscillator you‘re using?
Thanks! Glad you like it :) That's the Erica Synths Black Wavetable Oscillator
Great demonstration; what granular module are you using? The drones sound wonderful.
Thanks, glad you like it! And that's MI Clouds with original firmware.
I see it working along my no coast n my no ctrl… nuts
Adding together tempo synced LFOs into a matrix mixer is a great way to create timbral variation across multiple voices. Great for techno.
Hey, that's an awesome idea! Haven't used it like that. Would be cool indeed for different techno voices or percussion. Maybe even throw a looped cv recording in there, think that would be very performable :) Thanks!
I just got the Behringer 2500 series 1050 mix sequencer, I'm curious what techniques you've provided in this video that I can implement :) I can essentially use it as a 4x2 mixer or 8x1, so I should be able to pull off a few things suggested in the video. As always, thanks for sharing your discoveries and ideas!
You're very welcome! And that's interesting, let me know what works :)
Audio patch 1 is quite smart! Which modules did you use for the delay, granular processor and reverb? Thanks
Glad you liked it! Delay - Sythrotek echo, Granular - Mutable Instruments Clouds, Reverb - Xaoc Timiszoara. Cheers! :)
Lots of great ideas. Thanks fro sharing this.
Q: Is there a matrix mixer that all the knobs can be CV controlled?
Glad you liked it! And yes, but the price for those goes up, the 4MS VCA Matrix is a good example.
Another great video, thank you! May I ask a question please? The Bipolar Unipolar switch, does it work like a full wave rectifier, or a DV offset or something else.
The switch sets if the knobs in that column react like a unipolar or bipolar attenuator. So in unipolar mode, you can go from fully attenuated (to the left) to full signal (to the right). In bipolar mode the signal is fully attenuated/closed in the middle. To the right you can go to full signal. To the left you can go to full inverted signal. This acts like a polarizer.
@@MonotrailTechTalk thank you uou for taking the time to answer. That's a really useful feature. Cheers
Thx, cool vid! Will the doepfer matrix mixer work with guitar effectspedallevel and line outs of grooveboxes? Or do we have to convert everything to modular level and back?
You're welcome! And should easily work. You mostly just have to up the level of incoming audio if you want to use other modular effects like filters etc.
Hello, thanks for video and if I may ask a simple question please? - Can I connect say 4 mics each of the 4 inputs , and connect 4 Headphones to 4 outputs and selectively route inputs to outputs? My use case is to send selective mics to specific outputs only and not across the monitor outputs (As in Podcast mixer that connects all inputs to all outputs). Hope that makes sense. I hope these connectors support mics and provide phantom power
Hi there! You can connect any mono input signal to any mono output signal with this specific mixer. What you connect to what is up to you. No phantom power provided here of course- though. And if you like to process sounds from mics within the modular you probably need some input or gain module first.
This is all fine and dandy, but you might have no more space in your rack to fit a 20HP module.
You might probably have some single mixers (i.e.: The #Doepfer A-138n, which can process both audio and CV signals in 4HP only) in your rack.
All you need then is some multiples to split the same signal to input 1 of your mixers, another signal to input 2, and so on.
And there you have it.
Yes you can sort of fake it with multiple mixers. But the genius of the A-138m is the bipolar/unipolar switches and the fact that the first ‘channel’ is an offset with nothing patched to input one. These are great touches that set apart the A-138m from many other matrix mixers :)
@@kauwgomboom Of course, if can avoid fakin it, it's better.
#Doepfer makes GREAT modules, often underestimated.
It's my FAVOURITE manufacturer in absolute terms.
@@flourfree2K 4x a-138n + 2x buffered multiple = at least 20hp+ a lot of cables... so no, this module is more efficient and has more flexibility then your suggested alternative... it is also cheaper ;)
