CHA/V and Eurorack

Post by SynthularModulus » Sun Mar 15, 2020 10:12 pm

Anyone played around with a CHA/V and a Eurorack? Tell me about your patch and modules you used.

I just finished building a CHA/V and did a few initial tests. Looks like everything is working as should, but I need to play around with it more and learn what I am actually doing to get the kinds of results I would like to get.

I tried sending it various kinds of signals and cvs from my friend's Eurorack with mixed results. Audio, and Drum envelopes seemed to animate things nicely, but I wasn't able to get very useful results from the LFO and random CV. I assume I was doing something wrong with the patching on the CHA/V. I'll try again and see if I can get any better results.

Anyway, I didn't see a real CHA/V thread here and not much as it relates to Eurorack, so I figured I would start this thread to hopefully gather a few resources from folks and share anything useful I may (or may not) figure out myself.

Jonas is active on the FB Video Circuits page (, he's very helpful on all things CHA/V

a good trick with lower speed modulation for video is to mix it in with the faster rate signal before feeding it to the C/HAV (or other video module) - might be worth trying

This is a good starting point: ... anges/1641

Essentially you want frequencies that make your ears tickle. And if you want to use sub audio modulation, as suggested AM or FM it with a higher frequency
