BBD-based triple chorus generator
This is a BBD based triple chorus generator. It is inspired by the Choral generator in the ARP Omni, although the circuit is sort of based on one from Electronotes.
The circuit is DC coupled so it can be used to process CVs as well as audio.
As is, a signal patched into in 1 will be fed thru all 3 BBDs and arrive at out all, so the 3 BBDs operate in parallel as is done on the ARP Omni. The best effect is to modulate them with a 3 phase signal (I guess I better make one) or signals from a quadrature oscillator such as the NLC Feague.
If patched out 1 > in 2, out 2 > in 3, then out 3 to the Mixer/VCA, you will have the three circuits in series.
Alternatively, the three circuits can be used individually; patching to the inputs will break the internal routing.

These merchants probably sell this module. Huh?
