Thank you. I haven't read the technote, but I really don't want to touch Carbon, so that makes me happy to hear. The thing is that my calls to AudioUnitGetPropertyInfo, with kAudioUnitProperty_CocoaUI as the property fails with the error code: kAudioUnitErr_InvalidProperty. This happens with both Apple's DLS synth AND the third party device. I thought that was a bit strange. But from what you tell me, I think there must be something else that is wrong in my code, and that the AudioUnits do have Cocoa UIs?
I will look for errors elsewhere, in the meanwhile, it would be nice if someone can confirm that Apple's DLS synth does have a Cocoa UI view.
Thank you, and I hope you are not to annoyed by a hobby developer like me, who really only program for my own sake.
