CV-12

The Midimuso CV-12 ORAC kit

PCB assembled

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.

The IC which makes it all happen….

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)

Tested working in Chrome and Microsoft Edge.
Should work in Opera, Android Webview and Samsung Internet browsers.
Please make sure no other MIDI software is running (DAWs such as Ableton, Cubase etc.) as this app won't be able to see the available MIDI interfaces if they are already in use.
