Looking for general reactions on the following basic rack. I already have Subharmonicon, 2nd case, power, and the helix; this will be paired with an SQ-1 sequencer, and external patching from Reaktor (through cv.ocd). Audio out to a mixing board with send effects (Strymon El Capistan).

My goals are relatively "conventional" in the sense that I'll mostly be doing music with discrete pitches, manipulating melodic and harmonic polyrhythms, some of the good old LPG bongos. I have mucked around briefly with the sub+helix combo, and can clearly see the need for an additional envelope generator and VCA/mixer (which I guess I knew in advance). I'm not in any rush to complete the case, and am deliberately limiting myself to one module at a time until I've learned it well.

My question is for those with more hands-on long-term experience:
--Does this make sense as a unified system? Is anything clearly missing?
--Are any functions seemingly redundant? Some switch out you'd suggest?
--Is this ergonomically sensible?
