Updates to Music.h, deleted Midi.h and Midi.cpp
We can now use these commands in the arduino sketch: #define NUM_OSCILLATORS x // where x is 1, 2 or 3 #define BIT_DEPTH x // where x is 8 or 12 Deleted Midi library files as they where causing multiple definition errors with the outdated Music.h file.
