If your control is a continuous one (for example a slider), then you
have to issue a begin/end parameter change gesture notification -
there's a tech note on this at developer.apple.com/audio
You should also have a listener in your view somewhere, so I doubt
that the NULL values you are passing below are correct. If you have a
look at the usage of CAAUParameter::SetValue in the carbon view code,
you'll see how this is generally used.

Hi,
I'm making an automation part of my AU plug-in,
and I'm trying to make my own Carbon GUI class, not using
AUCarbonViewControl.
Here's the question:
How can I notify the host application that some parameter value has
been changed?
I want that the automation track's value is changed when I click
and adjust my GUI control.
I try AUParameterSet(NULL, NULL, param, value, 0),
but it doesn't work at all, just call MyPlug::SetParameter().
I'm on OSX 10.3, Logic 7.0.
Thanks in advance.
