  If my memory is correct, it had a whole bunch of waveforms, depending on
the 'quality' parameter.  These included squares and triangles.

  Would it be possible to computer-generate a bunch of numbers and make a
WAV file out of them that would be any pitch and any quality of sound?
If so, then the program could generate all the notes in all the octaves,
for several different 'instruments'.  Once this is done, then I do the
sound(pitch,volume,duration,quality).
