Is there a standardised default tempo ?

[Peter Billam]

Greetings.

Hope you're still here ... If a midi file is missing any set_tempo
event, my modules
http://www.pjb.com.au/comp/lua/MIDI.html
http://www.pjb.com.au/midi/MIDI.html
seem to assume a default tempo of 1sec = 1000000 microsecs/quarter
(I'm not sure about the Perl module, which I haven't checked yet:
http://search.cpan.org/perldoc?MIDI
)

Is there a mandated, consensus, or recommended Default Tempo ?

Regards, Peter

120 bpm. It is neither mandated, nor consensus ( well, maybe ) but it's
the default on every MIDI thing I ever used.

1 beat/half second is close to the human heart rate.

Nonsense. My heart beats at rest at about 78 bpm. I just checked.


Don't drink and drive. Unless you have a good cup holder.

Well, at 78 RPM you may be an old phonograph record, but you
must be in better shape than Les! <g>

The Standard MIDI-File Format Spec. 1.1 says:
| All MIDI Files should specify tempo and time signature. If they donn't,
| the time signature is assumed to be 4/4, and the tempo 120 beats per
| minute.

Ah, excellent, decisive :-) Indeed aplaymidi defaults to 120.
I will tweak my modules accordingly.

Thanks,
