USB Midi Controller for the ZOOM G3 (v.0.02a)
ZOOM G3 Guitar Multi Effect
Arduino UNO
USB Host Shield v2
LCD & Keypad Shield
(OK you should have an electric guitar too, for full delight!)
ZOOM G3 can respond to program change MIDI messages.
It changes the patch.
You can change the patch via keys etc.
After some researching, it's possible to send/receive MIDI over USB, using USB Host Shield v2.0.
All you have to do is to construct and send a 2-byte message.
Sample arduino code:
byte Message[2];
Message[0] =: 0xC0 // (Program Change);
Message[1] = (byte)map(analogRead(PotensiometerPin),0,1023,0,99);
Midi.SendData(Message);;
