In the SDK there are examples that utilise these API - PlaySequence. This example reads in and constructs a MusicSequence from a MIDI File. Of course, with this kind of source (MIDI File), the events constructed are MIDI events; however this is not the only thing a sequence can deal with. You can explicitly have Parameter events (including ramped parameters), and target different tracks of a sequence to different nodes (AU) of a graph. You can also define and schedule your own events using the user event type and callback.


Hi Bill, I played with this a bit and got it to mostly work. But the timescale is in "beats" per a set bpm. I'd like my events to be sample accurate. Is this possible with the MusicSequence stuff? I imagine I could set the bpm to 44100 * 60, but I saw you have a hard limit on the length of a track at 1bn beats-- so only ~377s. Am I trying to make MusicSequence do something it shouldn't?
