That sounds like a potential problem, actually. Remember, you only have 176 hp (of which 5 gets lost to the P/S module) in which to create something that does effects processing, sequenced patterns, AND generative processes. And from experience, it's possible to build something that DOES do all of that...but it ain't gonna fit in 176 hp. You're going to have to constrain the purposes here.
Since this is attached to a Minibrute 2s, go ahead and consider the sequencing part to be done. That simply leaves the timing aspects for that function. Effects: easy. There's even loads of space-efficient FX processors in the Eurorack domain.
Generative, however...to make really effective generative music, you need a LOT of modules that can transform one sort of signal into many different signals. So, we're talking about comparators for picking off gates from modulation signals, discriminators that can solve for minimum, maximum, or median control voltages, automated methods of globally changing modulation behavior, VCA complements that can function as mix automators, etc etc etc. Long list, basically. And if you don't go this complex, what you'll get will be the modular synth equivalent of one of those intensely-annoying "chirpy bird" electronic Xmas tree ornaments that only makes one or two sounds decently.
At the same time, it's TECHNICALLY possible to jam this all into a 176 hp cab...if you like moving three controls when you only meant to move one, and accidentally unplugging cables from a super-dense tangle of wires that overlays everything. There is a point at which you have to give way to the musical idea for the sake of making the musical instrument playable, though. In short, you might either want to scale down what this build is intended to accomplish, or consider scaling the build UP to a point where it's possible to do generative w/o it being a total snafu.

Thank you for that incite! I see what you're saying. I think I'll probably focus then on enhancing my sequences and standard synth capabilities (I sometimes plug a MIDI controller into it for the keys), while leaving room to begin a generative system which it sounds like I'll have to get another case to actually fully accomplish.
Does that sound like an actual direction? I know with modular, direction is everything. And if so, are these some good standard modules for a beginning?
