Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF ~$8 in parts, needing only one cross-board wire that shouldn't be over about 20mm in diameter at the bottom of the 3PDT so these issues don't arise. Then again, that would make for 7 wires to run, so maybe not. It works this way.
