Well, our very own Barry Taylor has a MIDI rendition of Suo Gan at The Contemplator site (click here). It's not quite the same tune I know, though. Here is another site with what I think may be the same MIDI.
Ah, finally, I found one that sounds close to the tune I know - Click here. This one is pretty close, too. All you need now is a MIDI program that will print the music on paper. Noteworthy composer is one.
Sorry, Barry, usually I think your MIDIs are great. -Joe Offer-
