CV-12

The Midimuso CV-12 ORAC

PCB assembled

This kit can be built for less than £20.00

You just need to order 3 items: the IC, the PCB and the parts – see the Shop page.

MIDI to CV converter using the Moog Volts / Octave CV scheme.
This board can produce
1V / octave or 1.2V / octave or 0.5V / octave just by setting the trimmer.

How does it work?
The CV-12 IC translates MIDI into gates and control voltages.
MIDI is fed in at pin #2 and the IC produces 18 separate voltage outputs which can be used in new designs or retro-fitted to a synthesiser.

The outputs include:
Note Gates
Pitch-Voltages
Control-Voltages
(max 11)
Aftertouch (channel pressure)
Pitch-bend
Auxiliary Gates (max 11)
Midi Clock (CT)
