Re: ComponentRefcon

If it's your AudioUnit, then you can add a property (see AudioUnitProperties.h for the ranges reserved for Apple and available for you) and do whatever you like with it.

If it's someone else's AudioUnit, there's no place I know of for you to do that. The component instance owns its own refCon. You'll notice in the AudioUnit sample code that we implement AU's as C++ objects, and use the component refCon to store a pointer to the AU C++ object.

What are good reasons for using or *not* using SetComponentRefcon(), (I
don't have the headers in front of me right now, but I think that's what the

This probably hilights a miscomprehension on my part, but it seems to me
that the refcon would only apply to the *single* component, as opposed to a
seperate refcon for each instantiated ComponentInstance, am I right ?

I'm looking for a way to store a pointer to some app specific data in an
open AudioUnit.
