  All it takes is clever programming. I once thought of doing an Amiga 8 voice
music program, but the total volume would be reduced to about 75%. Imagine
it this way. When two musical notes are played in harmony, it appears as
though a third not is produced. Of course the sound quality will not be
identical to a real 8 voice hardware piece, it can be done by averaging the
pitches or by using harmony combinations.

  One way to 'simulate' the harmony is to add vibrato (a slight vibration
in the sound, as if it is out of tune).
