Hello,
I'm new at this but I've put together the beginnings of a 104HP rack. It currently has the 4MS Row Power 30; the Moog Mother 32; the MusicThing Turing Machine; a Synthrotek passive DIY mult; and a Befaco Output V3 DIY.

I know I need multiple new, additional modules, but what I'd like your opinion on is: what would be a good NEXT module?
