troux makes a very good point here, as does Jim...the idea of building a "generative" system in 42 hp is VERY impractical. Having done work with those methods since...ah, crap, I dunno HOW long...I think I can safely say that you'll be lucky if you can get it to behave like a basic off-the-shelf monosynth. And while you apparently have other modular gear to interface this with, the idea that you can use only this live for generative ambient work in of itself is a pretty big stretch of the imagination.
20 more hp here would make more sense. 166 more hp would make a LOT of sense. You'll need it for the various modulation sources, control modules (comparators, anyone?), submixers, etc etc etc to arrive at a truly generative result. In fact, of all of the various modular paradigms, generative tends to require the size and diverse modular complements to be as MAXIMAL as possible, at least if you're trying to realize a schema that has multiple channels (as in an installation work), consists of a few different "lines" in front along with a "background" layer, and has a diverse palette of sounds that it can generate.
But here's how you can see how this'll work: build this 42 hp thing, and patch it up and let it run. If, after an hour, you've been driven insane by the limited sound palette and want to kick the skiff across the room at that point, DO SO. Then build a real generative setup.
