Hi Craig,

I haven't played with the MusicPlayer stuff much - but it makes sense that you have to start the sequencer. If you don't there won't be anything pushing notes into the Music Devices and thus no sound will be produced. Also the MusicPlayer is the one that knows when the sequence has ended. Starting the MusicPlayer will also start the output unit (if I remember correctly).

Hope that helps,

Robert.

Hi,
I am designing a export to aiff in my midi sequencer. I have read through DiskWriterAUGraph in the CoreAudio Examples. It is intimidating. I am trying to simplify the DiskWriterAUGraph, and convert it to Objective C mixed with C. I do understand much of it, yet in order to simplify the processing, I have one question - Must I give the MusicPlayer of a sequence a MusicPlayerStart() call to drive the data out of an output unit to render it, or can I simply call AudioUnitRender(,,,,,)? In the DiskWriterAUGraph example there is a call to MusicPlayerStart(). I would rather pull the data out of the output unit, instead of pushing it out with the MusicPlayer.
