Hi.
I'm hoping to get some ideas on how to implement a song position
display (i.e. bars/beats or time) for a sequencing app. I'm using the
MusicPlayer api, and my first hope was that I would be able to specify
some kind of notification callback function. I don't see anything in
the api for that (correct me if I'm wrong), so as far as I can tell I
have two options: 1) poll the MusicPlayer fairly often and update the
display as needed, or 2) create a metronome track in the sequence and
aim it at MIDIEndpoint that can advance the display. The first option
seems clumsy to me, and the second option seems like overkill. Is
option 2 an expensive way to achieve this? I don't have a lot of
experience with CoreMIDI so I don't know.
Any thoughts?
Thanks.
