Disklavier

As Bob noted, file Evergreen.mid is not a real MIDI file (despite the 
file extension).

I opened it in a hex editor, and saw the term "Apple Music Media 
Handler" near the bottom.  I dropped that term into Google, which got 
me to QuickTime.  Guess what -- it played just fine in the free 
version of QuickTime 5 I have on Windows XP.

My free version has no "SaveAs" function.  I suspect that in  
QuickTime Pro you could open it as is, and save it as a real MIDI 
file.  It'll take an Apple (or QuickTime Pro) user to confirm that 
conversion works.
