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

  • @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
      @MonotrailTechTalk  2 роки тому +2

      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!

    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
      @MonotrailTechTalk  Рік тому

      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.

    • @MonotrailTechTalk
      @MonotrailTechTalk  2 роки тому +1

      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.

    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
      @MonotrailTechTalk  4 місяці тому +1

      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.
