Trying out your wonderful patch idea, though I’m not quite sure what you mean regarding envelopes.
So you’re sending two gates that share a master clock, one into channel 3 and the other into channel 4, and 3 out is modulating channel 4 Both input? I tried sending two different gates from Marbles, one into 3 and 4 each, and didn’t really get the same acoustic timbres as you. But I think I’ve misunderstood this step.
Thanks for sharing the lovely patch idea!
