For guitars and contact mics, you would want preamp, so that way more than a buffer, but if you added preamps, you could use the rest of the schematic as is

@desolationjones I love this thought too and would want to point your interest towards an UNIVOX mixer and tape delay unit from LEM (an example for reference, I’m not selling this nor do I know anyone who has such a unit: https://reverb.com/item/519284-univox-lem-10-tape-delay-mixer)…maybe that’s just what your are looking for.

Edit: well, I’m sorry for confusing things a little here, I did ignore the fact that this is not a matrix mixer. Even if it resembles one aesthetically. Anyways…

#95

That looks like a neat unit but it would need 16 individual delays (4x4 matrix) to accomplish my dream. I’m going to try coding this delay matrix tonight on the ER-301.

I’ve been struggling to find ways to use my nlc matrix mixer. Is there some kind of basics of matrix mixer tutorial out there (for feedback and drone usages):ear_of_rice::cowboy_hat_face::ear_of_rice:?

One thing to bear in mind with eurorack matrix mixers is that a lot of modules (eg filters etc) are Inverting, so they won’t really feedback without the signal going thru something to invert it back again before going back to the mixer.

i would check out abes videos for some intro to matrix mixer ideas :slight_smile: that NLC is so nice with the voltage control too <3_<3

I could imagine an entire system being centered around the NLC matrix mixer … post-Tudor like … get some (logic) gates, comparators, filters, and modulation sources … game over

Finally put some knobs on my yomocircuits matrix. It’s about as compact as possible for my small rack and great to have gain knobs on each channel, knobs are of course a very very close together tho

One thing I’m learning is that because my matrix mixer (and most modules) are DC coupled, I can only get feedback going with a dc blocking capacitor in series. Prob going to have to solder up some cables with built in cap for this purpose to make life easier.

Also quite a few of my modules are Inverting which further complicates things feedback-wise

I use the good old doepfer 4x4 matrix mixer.
The thing is solid, has good knob spacing for playing it like an instrument and is shallow enough to fit into a 4MS pod.

Highly recommend

Hard to beat the Doepfer for price/performance. The polarizer and offset features make it much more useful than the various diy alternatives, and for not much more money.

Forgive me if you know about this, @qwoned, but if you can find an old Vintage Voltron 6 panel (assembled or otherwise; it’s all CGS PCBs), it’s a real joy. The switchable uni-/bipolar outputs are a real treat, and having four slews, wavemults and a resonant EQ round out a powerful standalone instrument on its own.

(I mention this, naturally, because you’re a Serge user)

whoa I didn’t realize it had res eq and vcm … that’s sick. I should switch out my BOG for this. thanks for the tip!!

#106

The matrix mixer has 1/8" i/o, and the resonant EQ has detented pots and a supplemental 1/8" input, too; it’s a lot easier interfacing with outboard.

not sure if this is of value to anyone in this thread but the quadratt can be used as a nice simple effects send/return - i find it especially useful as it’s in the 1U format and can effect multiple voices simultaneously.

*note this requires a stackable cable or a mult in order to work…

  1. patch the output of your efx unit to input (A) of the quadratt
  2. patch a stackable from quadratts output (D) to an output module or your mixer
  3. patch the input of your efx unit into the stackable at output (D)
  4. patch juicy sound sources to quadratts inputs (B), C, (D)

(A) controls the amount of efx you want in your mix while (B), C, (D) mix in those juicy sound sources i mentioned a few lines above.

if (A) is bipolar 12 o’clock is dry, CCW has a subtle blend while CW is more aggressive.
if (A) is unipolar CCW is dry while CW is fully wet.

for the record i have 0 ties to intellijel.

I’m looking into building a passive matrix mixer and was wondering – how many channels would be acceptable in a passive design? I realize this may be a hard question to answer depending on the set up.

#109

Maybe I’m looking at his wrong, but doesn’t this create a feedback loop with the EFX?
If the input going into the efx unit is coming off of D and going back into A then A and is getting to summed to D there there should be a feedback loop.

If you patched the FX mix from the A output instead of multing D that would solve it.

#111

I believe this puts the effect in a feedback loop (as A is sent out of the efx send). That can be very cool, I use something very similar with a quadratt and a Marantz 3-head tape deck to create echos.

To act as a traditional send/return, I believe you’d need to plug a jack into A’s out, and then send A and D outs to some sort of additional mixer (summing mixer, another quadratt, etc.)

ahh yeah it looks like it’s definitely not a traditional send/return situation in this configuration in the end.
though i’ve been testing this method out with a chronoblob and it works well. of course full CW completely maxes it out so

by “more agressive” and “fully wet” what i should have said is complete feedback chaos -
could be useful to sum
