The Midimuso CV-12 ORAC kit
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:
Control-Voltages (max 11)
Aftertouch (channel pressure)
Auxiliary Gates (max 11)
Midi Clock (CT)
Here’s the CV 12 Manual
Socket boards are now available for this board allowing easy connection of 3.5mm jacks (compatible with the Octex too) – see the shop page.
