Thanks for the info!  I've added it to the FAQ page.  You've done some 
AWESOME work on the MIDI applications for the PSIM-1.  I can't wait until I 
have some time to really sit down and work with it.  THANKS!!!  Your efforts 
are VERY much appreciated!

Also, I'm still making progress on the modules... more later.
