Here is a list of some MIDI files that will appear on a full page:
This is one of the most complicated MIDI files I have been able to find. It's the music from the "Exorcist". This MIDI file makes use of tons of features, including stereo sound. (Yes, QuickTime and QT MIDI Plugin both suppport full stereo sound!) Warning: This is a BIG, COMPLEX MIDI file, 315k, and will not sound very good on anything except the most powerful computers. It plays not too badly on my PowerMac 7500/100. It's about 25 minutes long.
This is a pretty neat file. It's "Mars the God of War" from Gustav Holst's suite, "The Planets." It doesn't make use of stereo sound, but is still a rather complex file. 58k.
This is a famous piano piece by Maurice Ravel. This is not a very complex file at all and should play back well on just about any computer. 27k.
You will also notice that by moving the mouse over the "QT MIDI Plug-in" title that this is also a hyperlink that will take you to my home page. Clicking on the QuickTime icon will again bring up the registration dialog.
