I'm not very familiar with many of the modules here, so I can't really comment on the capabilities of the setup as a whole. I would recommend grouping your modules by type to make signal flow more intuitive (e.g. sound sources together, filters together, modulation sources together, sequencers together, etc.). I have a Void Modular VCA, and it's not too bad for the extremely low price. I may pick up the Entropy Cannon someday.
What kind of music are you making?
