Put on some headphones!
Monotrail here on YouTube put out a great video today about slap-back envelopes, so I figured I'd give it a shot! Very simple audio chain again today, self-FM'd sine wave oscillator into two VCA's (left and right) which goes out directly with some hall reverb processed in parallel. The real magic is in the two envelopes, one (R) triggered by a square wave LFO and the other (L) triggered by the same LFO but pushed back through a cv delay. Three sine wave LFOs work to modulate different elements in the patch, one for modulating L envelope parameters, one for modulating cv delay time, and one for modulating the amount of FM in the oscillator. There's also a clever sequence patch too, perhaps something I should explore further...
