Urs' question about AU MIDI event scheduling reminded me of another
question that I've been meaning to ask:
A few weeks ago, I read a message from Urs on the osxaudio.com forums
saying that AU hosts could send MIDI events to AUs with frame offset
positions that are greater than the size of the next rendering slice. So
in other words, some MIDI events might not actually be for the next
rendering slice but for some rendering slice beyond that one, and so AUs
need to keep a "future events" queue for those. Urs said that Logic does
this sometimes, for example.
Is this true? And is it considered acceptable for an AU host to do this?
Thanks,
Marc
