4 things to do with a matrix mixer - Doepfer A-138m

[@gobgibbesnimmer]

didn't think I'd need one, but doing feedback patches taught me. that's why I started to build myself a vcamatrix.

[@MonotrailTechTalk]

Ah cool! VCA matrix for sure adds a lot of possibilities to the table, now I need to do another video :) Enjoy the build!

[@holydiver4728]

@gobgibbesnimmer Any progress on the vcamatrix build ? Are you doing a new build or combining excisting modules ?

[@rayderrich]

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).

[@MonotrailTechTalk]

Sorry about that! Haha :)

[@atdubya]

Nice one! Really appreciate the thoughtful demonstrations and animation describing how it works (Matrix mixing isn't always an easy concept to grok)

[@MonotrailTechTalk]

Glad you like it! And agree. If you know, you know. But if the concept is new a little demonstration can help :) Cheers!

[@mymodularjourney]

Great video again. I loved the part where you went into feedback. It’s such an interesting sound when kept in check.

[@MonotrailTechTalk]

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 :)

[@MartinDoudoroffLLC]

Superb video, and yes, please come back to feedback in the future!

[@MonotrailTechTalk]

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!

[@mrhappystacks]

I appreciate the little shadow you put on the overlay going into the jack. Its the little things!

This might be the best modular tutorial I've seen in a very long time. Thanks for your creative and methodical approach!

[@MonotrailTechTalk]

Thank you very much! Reading these kind of comments make it worth it :) All the best!

[@NiamorH]

I love the result of the 4 oscillators droning at 8:10 and the feedback patch as well ;)

[@MonotrailTechTalk]

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 :)

[@markjeffery3237]

Why is it that whatever module I look at, I immediately think, I really need two of those for flexibility😂 best modular channel on KZbin by a mile🙏🏻

[@MonotrailTechTalk]

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 :)

[@robotopsyrobotopsy6486]

By far you're the best Tips & Tutorial 'tuber' on the market. Really enjoying those.

[@MonotrailTechTalk]

That's nice to hear, glad you're enjoying my videos :) Cheers!

[@linewizard]

!! I need to get one of these. This is the most excited I’ve ever been over a doepfer module lol

[@MonotrailTechTalk]

Hahaha, sorry for causing gas :)

[@redwoodword]

Love the feedback possibilities of matrix mixers and would love to see your take on feedback patching.

[@MonotrailTechTalk]

Thanks! And hope I can get around to that sometime soon, it's on my list!

[@apeirogonmusic]

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

[@MonotrailTechTalk]

Glad you like them! That makes it worth it :)

[@davidmacdonald7679]

O M G I never considered matrix mixers. This video is like when I finally understood Maths. Now I need one!

[@MonotrailTechTalk]

Hey, happy to shine some light on the matter! Cheers :)

[@nitroanilinmusic]

To this point, I had no idea of any use cases for matrix mixers, nice video!

[@MonotrailTechTalk]

Glad I could help! And these are just some starting points ;)

[@ari_shark]

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!

[@MonotrailTechTalk]

That's nice to hear! And you're welcome, enjoy the module! :)

[@oldmossystone]

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 :)

[@MonotrailTechTalk]

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!

[@kauwgomboom]

Yeah you can basically create a Tiptop Z8000 using an A-138 and two A-151’s :)

[@5ToK3]

best tutorial for such an overlooked module thanks!!

[@MonotrailTechTalk]

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.

[@MonotrailTechTalk]

Great to hear you get some use out of it! Enjoy the experiments. Cheers :)

[@LeoPerantoni]

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!

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

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!

[@MonotrailTechTalk]

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! :)

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

[@MonotrailTechTalk]

Glad you like it! And nice, that sounds like a lot of fun!

[@bikramsingh2014]

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

[@MonotrailTechTalk]

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.

[@Tofu_Pilot]

Nice! I love a good mixer! Matrix mixers seem weird until you patch one up. Then you see how sweet life in the matrix truly can be :) AI Synthesis in Portland USA has both a regular and a stereo matrix mixer. They offer from PCB and panel only all the way to built and tested. Both are DC coupled so you can do CV mixing as well as audio.

[@MonotrailTechTalk]

Haha, agree! And stereo matrix mixers are super interesting for sure, might try one out some time. Cheers!

[@stujay]

Thanks for this! You have an excellent channel.

[@martintaylor9205]

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👍🇬🇧🕸🔱⚡️🌀🆒🎶🎶🎶🎶🌟🌟🌟

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!

[@MonotrailTechTalk]

You're very welcome! And that's interesting, let me know what works :)

[@dasczwo]

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?

[@MonotrailTechTalk]

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.

[@donhaugen1693]

Great demonstration; what granular module are you using? The drones sound wonderful.

[@MonotrailTechTalk]

Thanks, glad you like it! And that's MI Clouds with original firmware.

[@kosmikmusa]

Lots of great ideas. Thanks fro sharing this. Q: Is there a matrix mixer that all the knobs can be CV controlled?

[@MonotrailTechTalk]

Glad you liked it! And yes, but the price for those goes up, the 4MS VCA Matrix is a good example.

[@Banksyyt]

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.

[@MonotrailTechTalk]

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.

[@Banksyyt]

@@MonotrailTechTalk thank you uou for taking the time to answer. That's a really useful feature. Cheers

[@navicore]

great one. I have an a-138m and have not given CV mixing enough attention.

[@MonotrailTechTalk]

Nice, glad to add some ideas :)

[@ShivJG13]

That's it, you've convinced me to get one of these modules! I'm a total modular novice, so hopefully I'll be able to make good use of it. I have the A-132-2 quad VCA, but I struggle to make it work for me, though that's probably down to my incompetence. I bought it thinking it was suitable for audio, but I've since read it is a linear VCA, though I have had audio run through it so maybe it's okay for audio and I'm just not using it right! HAHA I already have another linear VCA (A-130) that barely gets used currently as I can't seem to find a use for it. Would the A-132-2 VCA be something I could use in conjunction with the A-138m?

[@MonotrailTechTalk]

Hey, nice! The matrix mixer is a great module for all sorts of things. A good modular building block you will use for a long time. So are VCAs, so just keep those and explore them more! Linear VCAs are perfectly suitable for audio, no problem at all. The linear / exponential just has to do with the knob control / volume increase curve balance.

[@ShivJG13]

@@MonotrailTechTalk thank you. I’ll try to learn how best to use my VCAs, and I’ll definitely get the A-138m. I can have lots of fun with that.

[@GeorgeLocke]

Adding together tempo synced LFOs into a matrix mixer is a great way to create timbral variation across multiple voices. Great for techno.

[@MonotrailTechTalk]

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!
