Hi,
If you look at the CocoaAUHost example, should be in your developer
directory, you can see how they implement the AUGraph, and also how you
can use any box on your View to display its UI in.
In a current project of mine, I'm using a group box to display an AU's UI.
Also, of note, you can control the AUMatrixReverb, or any audio unit,
programmatically through AudioUnitSetParameter()
Hope that gets you started.
