Hi edward,
Thanks for your reply.
I did manage to get a modified version working from the AUTimePitchTest code. I'm passing a range of values based on the UI slider position from -200 cts to +200 cts and see the expected pitch changes.
Do you know if the timepitchAU requires setting the output stream format explicitly? My application's audiograph so far just sets the output sample rate on the mixer and output AUs. This doesn't appear to be enough to get the timepitchAU to work.
Glad to hear it's working for you, so I remembered adding a comment about this in the AUTimePitchText sample.
From AUGraphController.mm:
// in an au graph, each nodes output stream format (including sample rate) needs to be set explicitly
// this stream format is propagated to its destination's input stream format
Search for that comment, you'll also see the code that sets the output formats for all AUs. If you started with that sample then it should be doing it already and I would expect things to work.
