Thread: Generative Ambient Rack
Not sure if you need the quantizer, marbles sends out quantized cv, and I think Pams does as well? But there are also smaller quantizers available to save space.
VCAs, while not 100% for audio in this set up, with the built in aspect of plaits and rings, are still valuable for modulation.
Using an LFO to control volume for long cross fades, etc.
