Host Callbacks
You should also be aware that these callbacks are described to only
provide information when called from your AUs render cycle. The AU
docs (/Developer/Examples/CoreAudio/Documentation) go into detail
about these and there are accessor methods in AUBase.cpp. AULab
provides a transport window that can be enabled so you can test these
callbacks.
Bill
In particular, I'd like to make a plug-in that can perform a
function, based on the current downbeat (as the sequence plays).
I've read through the documentation and can't even decide where to
begin. The docs say that most AU plugins are audio effects (not
necessary for me) or music "producers" (eg MusicDevice stuff),
neither of which sound like what I want. I don't need to process
audio at all, nor do I plan to make a peep. All I want is timing
information as the sequence plays. If anyone has suggestions to get
me started, I'd be grateful.
