First thing I notice is that you have no VCAs. They're crucial to any system. I'm not really in the "you can't have too many VCAs" camp (I probably don't have enough for my system, given its size)... but really, you can't have too many of them, and you seem to have none at all, except for the one in the Erica Pico-system.

You also have very little in the way of other utilities... mixers, mults, logic, switches, etc. These are the things that make modular interesting and strange.
