I've never been a MIDI expert but I'm now having to learn. I have a
question about this excerpt of a MIDI file viewed with hexedit.

Take the sequence "80 3D 35 31 80 3A 39 0E 80 37 31 03 80 31 1F" in
the first line for example. I know that 0x80 is note-off, and 0x3D
are
note number and 0x35 the velocity of the note-off. But what the
heck is
the next byte, 0x31? The MIDI standard says note-off is one status
byte
followed by 2 data bytes!

Midi events in a Midi file are separated by time stamps
