Another approach, that works very well in my
experience, is to not sleep the
total required time until the next event, but rather regularly sleep for very
short amounts of time (< 1ms), wakeup, measure the current time and if any
event time now lies in the past, simply play it back immediately. This way
the sleep time doesn't need to be accurate at all. All that's needed is that
it's small enough to get some decent timing.
I've now finished implementing this approach, sleeping around 10000
microseconds instead of less than 1ms, and it works very well! Thanks!
I'm getting very decent timing even with complicated MIDI files that have
numerous pitch bends at very short times.
I'm about to try your other suggestions later on.
Thank you very much.
