I'm writing an Audio Unit which will sport not only a Cocoa UI but a
Cocoa-heavy backend. The configuration state for this Audio Unit will
be managed by a key-value compliant objective-C class. So I'd like
to link up my Cooca UI with my AudioUnit logic through bindings.
The Audio Unit API is a "thinnish"-wire protocol, and it's good to
keep that if you can. I think Objective-C has a bunch of classes to
do with RPC (though I've never used them); maybe you can use those to
implement a richer protocol than the basic one without needing to
pass pointers around.
A word of warning though - I've just spent two years doing a
MusicDevice AU with a Cocoa UI, only to discover that the first
commercial host I've tested it with, Digital Performer, appears not
to support AU's with Cocoa UIs. At least, it doesn't bother to query
the AU's kAudioUnitProperty_CocoaUI property, and MOTU's support
department have not got back to me yet. So if you're developing an
AU that you hope to use with commercial hosts, you may want to take
that into consideration.
