I'm interested in doing some very accurate timing for a
MIDI application on the mac. That is, I need a precise timing
technique for MIDI playback and recording. Using the
Vertical Retrace Manager seems to be the obvious choice but
I don't think an interrupt every 1/60 of a second is fast
enough for this application. Taking over the timer used for
sound seems to be another choice. I think it interrupts every
horizontal retrace. Unfortunately, documentation in Inside Mac
is pretty sparse in this area. I would appreciate hearing about
better approaches or recommendations on how to solve this problem.
