i mean we hardcode magic numbers that 24 pulses are 1 beat
That's safe, I think. The internal resolution of devices may of
course be higher, and often is. 96 pulses per quarter note isn't
uncommon.
Let me clarify this a bit more; it's 24 pulses per quarter note, not
per "beat". How this is interpreted is up to the composer and the
listener. MIDI lacks a way to convey either of the numbers in a normal
time-signature indication and only conveys the passing of time
relative to quarter notes (or sixteenth, or....).
Higher level information needs to be agreed on by all participants by
(gasp :¬) ) actually talking with each other and entered manually into
all devices. Most of the time this poses no issues because the devices
will still be set to the exact settings that Greg assumed and 4/4 at
100 to 200 bpm is lots of fun. These would be good defaults, but
waltzing and 5/8 can be great fun as well.

As fluxus is quite tied to the "experimental" scene, I guess I'll have
to address this...
I've found this: http://ogloton.free.fr/midi/messages_systeme.html
It seems "time signature" and "bar marker" messages exist... I have to
understand what they do exactly ^^ and I'll come back with a proposal
for new functions!
