The ED107- PolyDAC(X) is a powerful and flexible 4-note polyphonic MIDI to CV converter that was originally designed by Paul Maddox (as a standalone 1U rack unit) with assistance from Tony Allgood who also initially marketed the product.

SPECIFICATION:
Resolution :- 12-bits on all analogue outputs
Gate (x4):- scaleable from 5V to 10V (factory build = 5.0V)
Note (x4):- 1V/Oct
Velocity (x4):- 0-10V
Pitchbend:- -1V through 0V to +1V
Mod Wheel:- 0V through to 10V
After touch:- 0V through to 10V
Sustain:- 0V, 10V when on
CC1, CC2, CC3 and CC4:- 0V to 10V
RETRIGGER :- When set to on and a new note comes in whilst an old one is held, the gate will ‘dip’ briefly.
Mode :- MONO1, POLY, MONO2
IGNORE/STEAL :- (Poly mode only) This allows you to select what happens to incoming notes when you have 4 held down. Poly1 new notes are ignored, Poly 2 the oldest note is replaced.
ASSIGN :- This allows you to assign MIDI CC’s to the 4 ‘CV’ outputs.

MODE:
POLY, this gives you MIDI to CV conversion for 4 voices, each with its own Note CV, Velocity CV and Gate. Also generated are CVs that correspond to PitchWheel, ModWheel, AfterTouch, Sustain and four user-definable MIDI CCs.

MONO 1, This mode gives you a monophonic MIDI to CV converter. The four voices all play the same note/gate allowing for some monster stacking of oscillators. It also has a choice of Retrigger mode and features a 16 note deep note stack. It has CV outputs for PitchWheel, ModWheel, AfterTouch, Sustain, as well as four user-definable MIDI CCs.

MONO 2, This mode gives you four channels of monophonic MIDI to CV conversion. The 4 channels all being consecutive (eg, 4, 5, 6 and 7). In this mode the PitchWheel, ModWheel, AfterTouch, Sustain and four user definable MIDI CCs are controlled by the MIDI channel assigned to voice 1 only. Retrigger sets retrigger on or off for all four channels. Each channel has its own 16 note deep note stack.

IGNORE/STEAL:
(Poly mode only) This allows you to select what happens to incoming notes when you have 4 held down. Poly1 new notes are ignored, Poly 2 the oldest note is replaced.

ASSIGN:
When the assign switch is held for a moment (approx 1 second) you will be able to assign the user CVs (CV A,B,C & D) to 4 MIDI controllers (MIDI CC).
By default they are:-
CV-A = 74 (Filter cutoff),
CV-B = 7 (Volume),
CV-C = 5 (Portamento time),
CV-D = 2 (breath controller)

MODWHEEL & PITCHBEND Sockets:
The Modwheel and Pitch bend sockets are slightly different to ordinary CV outputs. Plugging in a standard mono jack will give you the CV out. However, if you plug a stereo jack in, the TIP gives you the output CV, the RING then allows you to feed back into all 4 Note CVs, allowing, for example, a single LFO/VCA to control modulation on all 4 voices.
