Sure, just define your parameter to be write-only (there's a flag for
this in AudioUnitProperties.h).
Then, if you're not already doing so, you'd have to override the
SetParameter() method and handle
the parameter set there. Your code can completely ignore the
parameter value....

I'm porting an old AudioUnit plugin forwards to support a nice
Cocoa interface. 99% of the work is done, I've got sliders and text
fields and on/off buttons doing there thing and the AU Kernel
responding correctly. But there is one thing I can't work out - how
do I make my AU Kernel respond to a button click?
I have one button in the GUI that is supposed to clear a buffer. In
the button's action method, if I do AUParameterSet() with 'true'
for the button being pressed, then when my AU Kernel comes to get
that parameter, then from the first click onwards it will *always*
be True. What I've done to get around this is to have the action
method send a toggling value to AUParameterSet(), and the AU Kernel
responds to a change in that parameter. This seems like a horrible
kludge. Is there a more elegant way for an AU Kernel to respond to
a button click?
Thanks,
