 simple project which I hope the members will find interesting and usefull.
DIY bluetooth midi control for GP10 etc.

Uses
Digitech FS3X footswitch (unmodified). A cheap switch, thee switches operate as A , B, and (A AND B). Also works straight into GP10 as ctl3 and ctl4. 
Windows Pc with bluetooth adapter.
Wii remote controller.
Modified Nunchuck control.

Simple Nunchuck modification.
Connect a 3.5mm stereo jack plug (small to fit the case) to the 3 wires in the nunchuck which connect switch Z and switch C. Black to body, white to tip and red to ring. 
I diassembled the nunchuck and fitted the joystick assembly, circuit board and connected 3.5mm panel mount jack socket inside a small case. This might not be required as the jack socket could fit into the original body.
FS3X connects to nunchuck with cable stereo jacks 6mm to 3.5mm.

Simple scripts in the Glovepie program convert signals from the wiimote to midi data. In this example I have used different values of midi control 7 to set different pitch shifts on all strings. Transposing 0,5,7 semitones.
Many more functions are possible. The angle of the wiimote could be used as a controller, as an expression pedal.
