what app?
The app should be ensuring that you have a scope element on that scope
before it calls you. That said however, AUBase should be resilient to
this error and will rightly throw an exception for InvalidElement (or
InvalidScope) in this case. This is correct, so I'm not entirely sure
what your problem is.

After playing with the xcconfig for my audio unit, I've broken my

works fine, but I've spent far too much time comparing the configs
and
haven't found anything. There is an exception
thrown in GetAudioChannelLayout for scope 1 (input), which has no
elements since it's an instrument. The exception is caught by
ComponentEntryPoint<Class>::Dispatch(params, obj). Why is it that
the
input elements are queried when there are none, which AUBase
throws an
exception for? The queries work fine for the output scope, which has
18 elements.
thanks
