Thanks Michael

That does help, but actually I currently have no special handling for kAudioUnitErr_Unauthorized, if I got that result I would just fail and close the AU.

As far as I can tell, the PACE protected AU is popping up its own window and running a modal event loop.

I will check where in the call sequence this is happening and get back...

Thanks

Ross.

Ross,

Copy-protected plugins return kAudioUnitErr_Unauthorized on either open or Initialize. AULab can only handle audio units that throw this error on initialize. When it encounters an audio unit that returns this error, it presents the user with a dialog asking if they would like to authorize the audio unit.

The authorization window is created on the UI Thread. Not the main thread. The authorization window is created set to the key window and brought to the front. The Carbon or Cocoa Custom UI is embedded in that window. Once the window is closed, AULab goes on its merry way.

Perhaps your issue is either that you are creating a modal window.

AULAuthorizationWindow *uiWindow = [[AULAuthorizationWindow alloc] initWithAudioUnit: unit modal: NO];

// show the window

if (uiWindow) {

[uiWindow makeKeyAndOrderFront: self]; // window will be released when closed

}

Hope this helps!

Hi Everyone

I have a problem with my AU hosting: any plugins which uses PACE copy protection (paceap.com) display an iLok or PACE dialog when I instantiate them and then hang with all of the buttons on the PACE dialog disabled. I have only tested this with demo versions but my users are reporting similar problems with their licenced versions. If I try to use gdb naturally PACE exits immediatly. I see similar issues with VST and AU plugins.

I am guessing that I'm doing something with my event processing (which is going to be fun, since I'm using the Qt framework) but I wonder whether anyone has encountered this before and has any ideas how I might solve it. Or whether PACE provides developer support to plugin hosts for this kind of thing (thier dev. website seems to require you to buy a licence to enter).

Any and all thoughts and help appreciated.

Many thanks

Ross.
