Here's all three movements of Beethoven's Moonlight Sonata in MIDI Synth
format. I got the original MIDI files in the Internet news group
alt.binaries.sounds.music as part of the "Bert's Greatest Hits" collection.

The raw MIDI files were translated to MIDI Synth format by my program
MIDI Surgeon, which will be published in the Jan/Feb 1994 issue of GS+ 
magazine. To subscribe (magazine w/disk: 3 issues - $20; 6 issues - $36) or

The resulting sequence files all use the piano.bnk instrument file. The
volume seems rather low, so you may have to increase your system's sound
level for full enjoyment!
