Hi there,

I have been thinking on a "generative groove machine" in eurorack with using incoming main beat or drums to creative new texture.
I've made some test with Electus Versio and I think this is one good way to approach this (incoming audio > QPAS filter > electus > VCA triggered and modulated via Black Sequencer > CEQ for eq and compression).
I feel like I'm missing something to "add texture". In the computer world I would go for something like erosion basically.
I've comme accross a couple module such as Noise Plethora or Hexinverter VCNO but they are more about noise generator than audio effects, and I want something that can process existing audio, and not add an extra source (saving space in the case basically)
I've found QuBit but I don't really like the sound of it on the demo I've seen.
If you have any recommandation of a good module, stereo, that would suit I'm all ears out


maybe an fx aid... it has both bit reduction and some lo-fi algos...
or just get a noise source and mix a little in either to the audio or whatevers envelope you are using to open the vca

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities


Maybe something like this?

It all depends on what you mean by 'texture'. Maybe a waveshaper like Fold 6 will give you the 'texture' you're thinking of...

"Erosion" mostly makes me think of bit reduction/crushing and other audio degradation stuff. The Data Bender is the big one here, but you said you didn't like the sound of the "Qu Bit" (the company that makes Data Bender) so I'm assuming that's what you meant.

The aforementioned FX Aid could do the trick. It has several degradation/lo-fi algos (like Shallow Water, LoFi Junky, etc.), and it and you can apply voltage to its SRR input to reduce its clock and get bit reduction on top of that.

Other possible modules would be the VoicAs ReduXer, or maybe something like the Befaco Crush Delay. You can technically patch your own bit reducer with a S&H and superfast clock/audio rate triggering. Another option are various rectifiers, saturators and distortion units, but that possibly sounds more aggressive than what you want.

That's kind of what I'm trying to avoid here, I thought of that way, with an enveloppe follower and noise source, but that's require a lot of modules and a lot of patching.

Thanks! I'll check it deeper later, from what i've seen, it's more something like a looper.

I often use the Erosion to create "shakers" from other signals, it's kind of working like a noise and enveloppe generator I guess, but with nice controls on the noise source. I've checked a bit wavefolders and need to get my head around what they really does. The Fold 6 doesn't look as something made to treat stereo signal but like I said I don't fully understand what it does.

I missed a word. I looked at Prism from Qubit.
Erosion also have a "noise" mode that is different from but reduction, but I guess a good bit reduction could do the trick. I didn't checked all the algo from FXaid and I don't remember these algo. It could be a good option to try, and if it's not working I still can use it other way. This VoicAs module looks cool actually! Thanks!
About distorsion, I think this will be too agressive and affect the whole signal, I thought of something that add on top of existing sound, but maybe that doesn't really exist in such a simplistic way.

Not really... it only needs a 2 channel mixer & the noise source on top of what you already have (& you may already have the mixer) send the envelope from the black sequencer that you are using to open your vca and send it to a small mixer instead, also send the noise source to this mmixer, send the mix of the envelope and the noise to the vca instead of the envelope...

& both a basic noise source and plenty of basic mixers are kind of useful in the context of any modular synthesizer...

I would suggest the 4ms Tapographix delay, or even the Dual Looping delay (and use the feedback send to alter the original signals ?)
