// This is indexed by MIDI note number (0 to 127). Each entry contains
// two 4-bit packed values:
//     Low nibble:  Waveform step size (by octave) encoded
//         0 -> 1 step
//         1 -> 2 steps     Software must add one to the encoded value
//         3 -> 4 steps     to obtain the correct step size. The encoding lets
//         7 -> 8 steps     us fit the range [1:16] into 4 bits.
//        15 -> 16 steps
//     High nibble: Pitch waveform index
//         C  0    E  4    Ab  8
//         Db 1    F  5    A   9
//         D  2    Gb 6    Bb 10
//         Eb 3    G  7    B  11
