PolyDAC - About

PolyDAC 4-channel MIDI-CV

The PolyDAC was a 4-channel MIDI-CV Converter originally designed by Paul Maddox. Later the design was released to the general public.

The PolyDAC(X) is now available here, with permission from Paul Maddox.

It is available as a PCB with Component and Hardware Kits for installation in to your own enclosure and as a 1U 19" Rack both as a full kit and a ready-assembled unit.

The unit is available with 3.5mm, 4mm or 1/4" jacks and is supplied with a 15VDC laptop-style power brick (has universal mains input)
