It's very simple- I have a MIDI sequencer that is playing data that is updated in real time. I want to use a clock to check to see what has been added, and then send the MIDI data out. I can probably get reasonable accuracy using MIDIPackets, but it seems more direct to take control of the playback by use of an accurate clock.
Maybe that's not an option on OS X? I've done this on other operating systems, I'll be a little surprised if OS X doesn't allow it.
Thanks, Tom

time info from the host, and there aren't very many host apps. the API
seems to be mostly about using a given clock to derive other time
"units" (e.g. timecode) and isn't really related to the fundamental
issues of clocking. most (all?) hosts use the sample clock of the
audio interface they are using and derive timecode and the rest
internally - that's certainly going to be true of any cross-platform
host.
what are you actually trying to do?
