I need to monitor internal control signals, a load monitor, and a
spectrum display. I just define them as AU properties instead of AU
parameters - they can be read-only, and any old structure you like
(even a pointer, if you know AU's and their UI"s will forever share
the same address space). Then the UI just has an NSTimer which
checks their values around 12 times a second, which is generally
enough to avoid flicker.

Huh, this is funny. I was about to post this exact same problem to
the list last night, but decided to sleep on it and see if a solution
came to me (it didnt'). Also, does anybody know how one might get a
pointer to the UI from the actual audio unit? I'm afraid that using
a parameter listener won't quite hack it for me, because getting a C
callback routine won't have access to the class data I need to send
to the GUI....
