Hi,
When Core Audio builds its special Tempo track does it only look for
Tempo and TimeSignature events in track 1 of the Midi file? The reason
I ask is that I've only ever read that Tempo and TimeSig events are
*supposed* to be in track 1 but not that they *must* be in track 1.
For cross platform reasons I'm generating my own list of these events
and want to make sure I'm doing the same thing as Core Audio.
Any tempo event in the file is added to the sequence.
Ok - another quick question relating to this. What does Core Audio do
if there are two or more tempo events on different tracks with the same
starting time? If they were on the same track I imagine the last one
read from the file would take precedence but what about different
tracks? It looks like it could go several different ways depending on
the algorithm used.
thanks!
Peter
