Instead of calling SetParameter, you should call AUParameterSet
(<AudioToolbox/AudioUnitUtilities.>) - its nearly as simple :)
AUParameterSet appears to be a wrapper around SetParameter that
also fires an event off, have you tried that?
Yes, I am aware of the difference between AUParameterSet and
AudioUnitSetParameter. The question is why AudioUnitSetProperty( ...
kAudioUnitProperty_PresentPreset, ... ) seems to fire events (at
least the GUI responds to changes) whereas AudioUnitSetParameter
doesn't. I know I CAN fire events off with AUSetParameter, but I'm
unclear why the functions from AudioUnit.h seem to have different
behaviors (as opposed to functions from AudioUnitUtilities.h).
This seems inconsistent, but as I said, it's immaterial at this
point, because I decided to fire events manually with my own wrapper
function.
