It’s just a start for now, but if you go check out the code page, you can find working code and the binary for adding MIDI over USB functionality to the V1 guitar.  All you need to do is download the binary file and then update the firmware with the .hex file, and it will then show up to your computer as V-USB-MIDI.

It’s somewhat limited in its current state, and based on how the V1 interprets data, it’s never going to be a particularly great MIDI guitar.  In its current state, it only can produce accurate data for individually fretted notes, so using capos and chords isn’t effective for generating music.  However, since the V1 circuitry doesn’t interfere with the circuitry of the underlying instrument, it’s  a great way to provide a secondary data stream from any stringed instrument.

Possible applications include:

• Controlling stage lighting
• Controlling effect pedals
• Experimental music production

Also, remember that this is first-generation code – if there are any bugs or if you notice something acting unexpectedly, please let me know at develop@openchord.org

Of course, with the MIDI firmware, the V1 won’t be able to play with any games – you’ll have to reflash the firmware to the standard V1 code if you want that.
