After more digging, I found kAudioUnitPropery_PresentationLatency in AudioUnitProperties.h . I haven't been able to find any detailed documentation, but have found one ore two mentions of it on the mailing lists. This seems like what I need for accurately scheduling MIDI events in the future, so I'll give it a try. If anyone has used this with an Audio Graph setup, and cares to offer advice on implementation, I'd greatly appreciate it.
I recall reading elsewhere, possibly about a similar HAL property, that the latency may vary during runtime. Is this something I need to keep an eye on? Is there a proper way of doing so that won't become a bottleneck? (Checking the property constantly that is...)
best,
Greg
