personally I would have fewer sound sources and get full size ones so that they are easier to play with

but more seriously, I would dump the ochd - pams and maths (plus pachinko) is enough modulation in this size case imo - instead use utility modules, such as mutable links and kinks and a matrix mixer to derive lots of related modulation

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

sound sources < sound modifiers < modulation sources < utilities
