Hi Tom
"..Thus is there any
(simple) way to predict the total number of audioframes that will be
generated when rendering a single midi file? Or how to get the total
time this midi file will play?"
Taking account the fact that a MIDI file may contains "tempo changes events",
the only way to known by advance the total time this file will play is to write
a procedure that look inside the file and compute this time. The principle to
do that
is not too complicated, if you intend to do that and don't know how to do , i
think i can
give the way.
regards
jjc
