Because there are callbacks in it and because mach-o is the standard
binary format for Mac OS X, we do not expect and will not support CFM

BTW - There is also a property call kAudioUnitProperty_FastDispatch -
you would break this as well if you were using CFM.
Why do you want to do this?
Waves has its own internal plug-in format and we use a shell to adopt
it to
specific platform. Our internal plug-in is still CFM, so I thought
making a
CFM shell would reduce development time. I guess that I can't ignore
Mach-O
forever.

Hi,
Is there any reason why an AU can't be CFM ?
AU is basically a Component. According to the documentation a
component can
be either Mach-O or CFM. The only problem I can see is the render
notification
callback function.
In AUBase::DoRenderSlice the AU notifies all the saved
AudioUnitRenderCallbacks.
This call can be any combination of CFM and Mach-O which might lead
to crash if
it's not properly glued. Am I missing something obvious ?
