AudioUnit as parameter listener?
AudioUnit as parameter listener?

I notice that in the template generated for a new Audio Unit effect, the parameter values are obtained in the Render method via GetParameter().
Is this the normal way of handling parameter changes?
My current plug-in modifies the DSP's parameters whenever the user makes a change to a control. (My Audio Unit version is a VST plug-in wrapped in the VST2AU software, so it's the same as the VST in that respect.)
What I'm wondering is, is calling GetParameter() for every parameter the normal way of handling parameter changes, even in plug-ins with more controls? Or, is there a function I can override or a message I can trap when the parameter is changed via a call to AUParameterSet() by the view? Or, should I set up a listener for the parameter change, the way I did in the view?
Thanks,
Howard
