Nexus-GK is a small, flexible, and hacker-friendly breakout box that connects your multichannel guitar to the outside world using a specialized 19-pin (LEMO compatible) multi-pin connector with 15 channels of combined audio and analog control voltages and switches, for remote control of volume, EQ, patch or effects. Audio may come from standard mono-pickups or the Nu multichannel pickup. Analog control voltages are converted to MIDI control messages. Outputs include 12 channels of audio, MIDI 5-pin DIN, and a 13-Pin, Roland compatible DIN.
