"Elby Designs PolyDAC 4-voice polyphonic MIDI-CV converter in very good condition. I purchased this unit a month ago and it is in like-new condition. There is a small locking piece missing from one side on the rear of the unit, however the unit still functions perfectly. Polyphonic mode, two different monophonic modes, 4 MIDI CC outputs as well as Pitchwheel, Modwheel, Aftertouch and Sustain outputs. Comes with brand new 15V power supply for use with US outlets.

I have pasted the manufacturer's description below for your convenience. Please don't hesitate to contact me with any questions. Thanks!

This module not only gives you a four note Polyphonic mode, with selectable assign method. But gives you two more, versatile, monophonic modes. Effectivly replacing not one but four MIDI to CV converters in one easy to use 3U wide Module.

Poly Mode, this gives you Midi to CV conversion for 4 voices, each with its own note CV, Velocity CV and Gate, along with pitchwheel, modwheel, aftertouch, sustain and four user definable Midi CCs. A choice of Polymode allows note steal or note ignore for new notes once all 4 voices are in use. With note steal mode on you can also turn retrigger on or off, which will retrigger the gate for the new note.

Mono 1, this gives you a monophonic Midi to CV converter. The 4 voices all play the same note/gate allowing for some monster stacking of oscillators. A choice of retrigger mode and a 16 note deep note stack. Also with pitchwheel, modhweel, aftertouch, sustain and four usef definable Midi CCs. Again you have the option for retrigger or not.

Mono 2, gives you 4 channels of monophonic Midi to CV conversion. The 4 channels all being consecutive (eg, 4, 5, 6 and 7). In this mode voice 1 uses the pitchwheel, modwheel, aftertouch, sustain and four usef definable Midi CCs. Retrigger sets retrigger on or off for all four channels. Each channel has its own 16 note deep note stack.

Other features

Assignable CVs, so you can choose which MIDI CC's you wish to use to control your modular. By default they are CV-A = 74(Filter cutoff), CV-B = 7(Volume), CV-C = 5(Portamento time), CV-D = 2(breath controller)
The pitchwheel CV affects all 4 note CVs Via the bend range knob. However, If you plug a jack into the Pitch wheel CV socket the pitch CV is no longer applied.
The Modwheel socket is slightly different, Plugging in a standard mono jack will give you the Modwheel CV out.
But, if you plug in a stereo jack in, the TIP gives you the Modwheel CV, the RING then allows you to feed back into all 4 note CVs, allowing a single LFO/VCA to control modulation on all 4 voices.
The MIDI light flash with each Midi message it receives and understands, eg, note on/off will cause it to flash, Midi clock and Sysex will be ignored."
