0xf9 is Undefined (Reserved), according to:
http://www.midi.org/techspecs/midimessages.php
[snip]
It is an useful site, because the official MIDI specification is not published
online my midi.org, but it is not an official source. I would like to know
the origin of this "tick" 0xf9 message. Is it an addition from some
manufacturer?
Good point, Pedro. I think your right, it smalls like a
vendor extension. FWIW, elsewhere on the same site 0xF9 is
also marked as unused.
