3.4 WDATA - Wave Data
*****************************************************************************
A Wave consists of 128 eight Bit samples, but only the first 64 of them are
stored/transmitted, the second half is same as first except the values are
negated and the order is reversed:
Wave[64+n] = -Wave[63-n] for n=0..63
Not that samples are not two’s complement format, to get a signed byte,
the most significant bit must be flipped:
signed char s = Wave[n]^0x80;

3.5 WCTDATA - Wave Control table Data
*****************************************************************************
A Wave control table consists of 64 entries that indicate a wave
for the specific position. If the index is not valid, the position
will be filled with a spectral interpolation of the neighbour waves.
The last three Waves will always be triangle, square and sawtooth,
and the first index must be valid. Valid indices are currently:
0-200 for ROM Waves 0 to 299,
1000-1249 for User Waves 1000 to 1249
