Hi Jeremy,
I don't think so - I don't want to get involved in the listening side
(well except when I'm establishing a link between an AU parameter and a
MIDI CC). I just want to tell the AU to change a parameter (using
AudioUnitSetParameter) and (if the AU's UI is open) for the change to
be reflected in the UI.
What I'm doing works for many MusicDevices such as buzZer, Claw, any of
the LinPlug synths, etc. though there are some notable exceptions.
Robert.

Robert,
I am not sure exactly what you are trying to do but it sounds like you
should be using AUParameterSet.

A follow up...
Now maybe my plugins are way out of date - but I can't find an effect
UI - generic or otherwise - that updates itself based upon changes
coming from AudioUnitSetParameter.
Is there one around that I can test with?
Thanks,
Robert.

I just added MIDI remote control for Apple's effects using
AudioUnitSetParameter to change the values and to my surprise and
disappointment the UI does not update even though the AU recognizes
the changes and changes the DSP. I would have thought the generic UI
code would have been updated to post notifications when this
function is called? It makes automation/remote control a lot more
friendly.
Thanks,
Robert.
