Thread: First generative rack
Couple of things.
Quadra is discontinued... unless you're looking for a used Quadra, Quadrax is the new version (tons of added functionality, too).
Turing Machine is terrific... but Mutable Instruments' Marbles is essentially an expanded Turing Machine with added functionality. It's really terrific, and I'd suggest using it instead of the TM and expanders.
You don't have a filter in either version... that seems like a serious omission, especially given your oscillator choice.
