Audio Unit V2: kAudioComponentInstantiation_LoadInProcess?

Hello all,


I'm seeing that Final Cut Pro and Garageband use InfoHelper to validate Audio Units now, whereas Logic Pro X still uses auvaltool. After some debugging I've noticed that InfoHelper uses worker threads to instantiate audio units.


From what I understand after watching the WWDC video on Audio Unit Extensions, V2 Audio Units should still be loaded 'in-process' by the host, but I see this isn't occuring during validation.


Does anyone know if it's possible to use this new flag for instantiating v2 audio units? I have a requirement that the app must be created on the main thread (using Qt as a graphical frontend). Seems that something along these lines may help.


Cheers

Daniel
