This program displays a real-time audio spectrum for a protracker module
as it plays. It can also drive the parallel port bits (PB0-PB7) in response
to the presence of certain frequencies. This can be used for triggering 
external hardware as the protracker module is playing (although I can't see
myself using it :-) ).
This program doesn't support compressed or 15 sample module formats.
