Hi Bill,

I see that, in my code, if I remove the setShowsExpertParameters: call the F8 AU displays ok, like in AULab. However, the iZotope Vinyl AU does not display properly, and also crashes AULab when selecting the generic view.

The F8 and Vinyl AU's pass validation, but the DestroyFX transverb does not.

This code is provided by people in the QT Group - you might want to ask them (QT API)

You can also validate the AUs you are using - run the auval tool on these. If these AUs pass or fail validation would be interesting to know.

You can also host these AUs in the AU Lab application (/Developer/ Applications/Audio/) - you can bring up either their custom or show their generic views. If the AUs have expert parameters, then you'll see a disclosure triangle that when expanded, will show the expert params. (Oh, expert params are params that are marked with the "expert" flag - so they should not normally be presented to users)

Bill



I looked at this a bit with F8. The crash with F8 occurs at line 1898 of SGAudioSettings.mm "[auview setShowsExpertParameters:YES];"


What does setShowsExpertParameters turn on? If I comment out this line and then load F8, it doesn't crash. But, the GenericView shows a random subset of the F8 parameters when it is loaded.

If someone can point me at documentation for AUGenericView, perhaps I can figure out what parameter information F8 is providing that is instigating the crash.
