I like all the doepfer wavefolders - I have all 4 - but I use them for video

They can be picked up very cheaply used - so are worth a try - even if you resell them

for audio I'd pick one of the other ones though - or a Befaco Chopping Kinky

I'd also want more basic utilities for modulation purposes - kinks and a matrix mixer would go a long way, possibly a sequential switch

"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
