Oh man, I went and I read about arrays, and yeah, that would be easier...
So my code would look like this?:
int buttonPin[11];
int buttonVal[11];
int buttonState[11];
int buttonCheck[11];
int potPin[8];
int potVal[8];
int mappedPotVal[8];
int prevPotVal[8];
int potTHRESHOLD[8];
int faderPin[4];
int faderVal[4];
int mappedfaderVal[4];
int prevfaderVal[4];
int faderTHRESHOLD[4];
