N64 Midi Tool by SubDrag at 12:57 PM EDT on September 10, 2011
Just wanted to mention there was an issue where I didn't carry forward the delta time of midis for the loop command, so there may be some small errors in previously extracted midis.
I also added export support to MIDx format used by some games, but not import. It uses a simplified fixed size midi format.
