Also...
mEditAudioUnit is actually of the type ComponentInstance (which
AudioUnit is typedef'd too). Any calls made to that object have to go
through the component API - it isn't the "this" pointer.
If you need to pass data between your AU and view, have a look at the
FilterDemo example in /Developer/Examples/CoreAudio

Hi. I'm new to Audio Units, am not sure if this is the right
place for this, but I was hoping for some help on something.
Starting with the Audio Unit with Carbon View Template,
Say my effect class Foo inherits from AUEffectBase
Say my view class FooView inherits from AUCarbonViewBase
In FooView shouldn't I be able to call a function in my effect
object with the following:
Foo* effect = (Foo*)(mEditAudioUnit);
effect->myFunction();
or maybe the first line needs to be:
Foo* effect = (Foo*)(&myEditAudioUnit);
Either way, any variables in Foo that myFunction uses are not
initialized, it's not pointing to the original effect object. Help?
No. You cannot assume that the Model and the View are in the same
process or address space.
