Thanks for so much detail and suggestions! I thought and made some changes to the plan. Zadar looks amazing for ambient/drone/generative/noise which is the aim of this rack.
quadra is sufficient for regular envelopes when paired with zadar, rather than quadrax
contour is gone - can use ASR from quadra
maths is gone - big call, but quadratt does cv generation/attenuversion, pnw does lfos, plog covers the logic, quadra & zadar do envelopes, not too much missing?
added zeroscope to help me figure out what the hell is going on with my signals, and to tune oscillators (any midi sequences will be coming in from an octatrack). Once I’m more experienced this could be replaced.
buffered mult is now 3u, that’s a great call!
this leaves a nice 36hp at the bottom for synchrodyne+expand in the future - it would be a while before I can afford that anyway, and buying more modulation and EG first will get me more out of what I have already, just as you said.
Logic I will need to look into in much more detail including the u4r. For now I can get a random stepped voltage out of Pam’s and a bunch of triggers from plog.
This also leaves me with some kind of structure L-R of (midi/triggers/gates)-envelopes-oscillators-vcas/filters, which feels better thought out and tidier than before:
