Wave after wave of chromatic dissonance. Each wave unique in it’s unpleasantness!
Anyhow, it’s 12 VCOs->12 ADSR->12 VCAs->Mixer.
Each VCO is tuned to a note C through B (over three octaves). The LFOs affect the amount of FM for the VCOs.
The clocked random gates trigger each VCO.
You could throw a quantizer on this and get something more pleasant.
