so what's missing??

imo definitely utilities

a nice matrix mixer perhaps? maybe keep it small - rebel technology mix04?

kinks and shades would also add a lot

that will fill your 20hp - use them primarily for processing modulation

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
