yes you could replace the doepfer s&h

personally I would remove the cold mac and the precision adder - add panning mixer (for audio - panmixjr) and a matrix mixer (for modulation - input 4 modulation sources get 4 different mixes out)

"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia

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

sound sources < sound modifiers < modulation sources < utilities
