Here's the entire program. I'm using a repurposed joystick and some knobs to control pitchbend, modulation, cutoff, resonance and LFO speed. It is really odd, I've re-ordered/edited the array of analog ins, pretty sure that any 3 will work, but a 4th one won't.

int Res_grp[2]={21,30};
int Cut_grp[2]={51,29};
int LFO_grp[2]={3,16};
int Resonance,Cutoff,LFO;
int Mchan[2]={0,3};
// #define Moog_LFO 3
// #define DM_Res 30
// #define DM_Cutoff 29
// #define DM_LFO 16
#define Pitchbend 2
// 2 LEDs
// 1 joystick
// 1 switches - select device
// 2 extra Knobs
