\nThis board can produce
\n1V \/ octave<\/strong> or 1.2V \/ octave<\/strong> or\u00a00.5V \/ octave<\/strong> just by setting the trimmer.<\/p>\n

Can be used with Midimuso socket boards (available in the shop)<\/p>\n

\"\"<\/a><\/p>\n

How does it work?
\n<\/strong>The CV-12 IC translates MIDI into gates and control voltages.
\nMIDI 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.<\/p>\n

The outputs include:
\nNote Gates<\/b>
\nPitch-Voltages
\nControl-Voltages<\/b> (max 11)
\nAftertouch (channel pressure)<\/strong>
\nPitch-bend<\/b>
\nAuxiliary Gates\u00a0<\/b>(max 11)
\nMidi Clock <\/b>(CT)
\n<\/b><\/p>\n

See it being built in this review video<\/a><\/p>\n

Ruben van Heerden has designed a a 3U height (for\u00a0 Eurorack) front panel and 3d-printable box.<\/a><\/p>\n

The IC has many modes for different uses.
\nThere is an easy to use online tool for easy CV-12 mode changes (see below)<\/p>\n

Socket boards are now available for this board allowing easy connection of 3.5mm jacks – see the shop page.
\nThey are NOT included in the full kit and must be purchased separately. We recommend you buy at least two socket kits to cover pitches (port B) and gates (port D),\u00a0 but you can get started with just one set using Dupont cables (see diagram above).<\/p>\n

Tested working in Chrome and Microsoft Edge.\nShould work in Opera, Android Webview and Samsung Internet browsers.\nPlease 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.<\/pre>\n
