Much of this is Hannu's code as distributed with the sndkit.  See the
individual files for his details.  The gusthru program is a reworked 
version of his midithru code.

As such, this code works with the Voxware driver.  I am currently using
tclmidi to run my MQX-32 midi card, and Voxware to run my GUS so that I
can use it as a synth.
