Somehow you have to tell the external world that you've changed
something that it knows about...
So, instead of calling AudioUnitSetParameter you can use the
AUParameterSet call that is defined in
<AudioToolbox/AudioUnitUtilities.h> - that will notifiy any listeners
(like Logic your host) that your GUI has changed the value of a
parameter - that is how the Generic View works for instance (and the
view that Logic puts up).
AUParameterSet is very similar to AudioUnitSetParameter (and in fact
just makes that call for you as well as doing notifications for any
listeners)...

So it does not seems to be a Logic bug, but what could it be then ?
