Seems kinda short on envelope gens, actually...this could use a few, maybe a Quadrax would be useful. Also, some attenuverters would be useful. I'd suggest the Roti Pola, but you can't break out the individual pots if/when needed, so an Intellijel Triplatt seems like a better fit. Aside of those, this seems to have a lot of bases covered...might benefit from a reshuffle to get the audio and CV/mod paths in a clearer arrangement, but other than those, not too shabby.
