euro: self-influencing matrix mixer modulation thingy

Post by cptnal » Wed Jun 26, 2019 6:04 am

Just noticed this one. Two months and no patches? Booooo.... :razz:

I'll start then. This is my self-influencing matrix mixer modulation thingy. Adjust matrix pots and LFO frequency start values to taste, and use Batumi's variable outs to modulate your voice's parameters. Also generates pitch from the squares.

Special mention to MarcelP who described most of it before I did. But I didn't steal it, honest. :mrgreen:

Nice. Can you elaborate more on the Batumi? What mode is it in? What is the idea in terms of mixing different feedback levels into it?

Thanks, and sure I can...

Batumi's in free mode. I don't see much point in using quadrature mode, but the others could probably yield some funky results. I'll get round to experimenting with these eventually.

Basically what we're doing here is getting four chaotic outputs (or eight if you tap the mixer outputs as well - they'll be different) for the price of four vanilla inputs. It can go from gentle to crazy - and back again - depending on the initial frequency of the LFOs and the amount of modulation you feed back into their FMs.

Tapping the squares for pitch gives you a limited number of values for your "sequence". A bit of careful attenuation in the second mixer can give quite pleasing results. Of course you don't have to use it for pitch...

...and as I've been typing this I'm wondering what if we use jaggy saws instead of smooth sines... :hmm:

Ah, so the mixer serves a "depth of frequency modulation"/"index" function. Obvious in hindsight!
I'd imagine the "divide" mode would produce the most harmonically satisfying results. "Free" mode is probably a free for all.

Try these:
* set each of the outputs to a different waveform in free mode
* set each of the outputs to a different waveform, at the same frequency
* set each of the outputs to a different waveform, at different frequency divisions

Coincidentally uploaded some Instacrap sounds revolving around this technique:

A bit fresher on the ear than how I've been using it, but demonstrates the versatility of the patch. Liked the middle one. :tu:
