Nicely done! At first glance, one might be tempted to ding it for being short on linear VCAs, but then there's several VCAs in the tile rows, plus the subsystems in the mixer do lots of audio-type heavy lifting. Even so, dropping something like an Erogenous VC8 in there would really punch up the CV/mod handling craziness and add some mixing/attenuverters to those signal paths. And actually, this has the room for the entire Erogenous Tones audio/CV lineup of VC8, Levit8, Radar and Blip if you can find enough to drop or leave room for in the future expansion.
