Unknown data inside MIDI file

unknown_midi_data.txt

If anyone can figure out what this data is, that would be greeeaaaat.  Bytes represented in hex.

Found inside a MIDI file between tracks.  Surely it's related to music somehow, like a sample..?  Not sure.
I've inserted newlines after 99 and 89, which seem to be very common bytes.

Looks suspiciously like assembler. http://www.avrfreaks.net/forum/interrupt-service-routines-xmega
