O.K.
BUT
One thing that I think we did well with AUs was to distinguish between
the model and the view of the DSP. If Cocoa is good for UI and your
preferred UI choice, then it is certainly easier for a Cocoa based
hosts to host a Carbon UI than vice versa.
I agree with this, including the model-view separation. But, it only
helps the host developer.
All of the strengths that have been discussed about Cocoa relate to
the UI capabilities - and if/when we do do work in this area it will
be in that aspect of the AU - its view.
I don't see us changing any of the implementation and container of the
DSP code (the AU proper) to be anything but C/C++ anytime soon.
However, that doesn't mean that's the only way that the API for users
of AUs or other CoreAudio APIs will be published.
Cocoa has advantages other than UI. The reason I think that we are
mainly talking about UI is that this is the only thing the Cocoa people
can't do anything about.
I would like to see the SDK in Objective C. If you choose not to
provide this, we can write our own. Just as people have already
written Objective C API's for the HAL and some of the AU.
When It comes to the AU UI, we can't fix our problem.
Thanks for the reply.

It was gently pointed out to me in a private email, that my arguments
about the age of the Carbon library where wrong (and silly). I think
that it is important to correct myself on this point. The design and
implementation of Cocoa is nearly as old as Carbon. Cocoa is
actually a mature and well tested library. My point should really
have been that Cocoa is the best UI development platform out there
(anywhere) and Carbon isn't.
Again, thanks for all the feedback on this. I really would like some
from someone at Apple, even if it is just to tell me I'm out of luck.
If Apple isn't going to be giving us Cocoa based AU's any time soon
then I will set up my own plugin format for the app I'm working on.
I will lose all of the nice stuff from AU graphs and I will have to
build adaptors between AU's and the other plugins, but I think it
will be well worth it.
