I've implimented a java music app that uses coreaudio to dynamically generate and perform with midi. It has a swing interface and ran ok (if slowly) in 1.3.1.
I upgraded to to 1.4.1 and added:
-Xbootclasspath/a:/System/Library/Frameworks/JavaVM.framework/Versions/
1.4.1/Classes/CoreAudioSupport.jar
to additional VM options.
I've cleaned, polished, created a new project, searched for solutions, even rebuilt standing on one leg holding my breath with my eyes closed... and still it does not work.
It seems to still want to use JDirect once I call myAUGraph = new AUGraph();
(stacktrace below)
I seem to remember installing an early 1.4.1 preview version months ago and then disabling it when I discovered it would not work with coreaudio, so I'm not sure if that might be the problem or how to fix it :(
I need to give a talk to my university department tomorrow night and demonstrate this app and I'm sure 1.4.1 will perform a lot better!
many thanks,
Damien
