Hi there
I have an application which creates an AUGraph consisting of a DLS
node connected to a mixer connected to an output node. This ran
find on 10.3 and 10.4. I'm now finding, however, that it crashes
Leopard at AUMixerEntry. Any thoughts?
Here's the code (updated for 10.5 APIs):
error = AUGraphNodeInfo(gAUGraph, gPianoNode,NULL, &synthUnit);
error = AudioUnitSetProperty (synthUnit,
kMusicDeviceProperty_SoundBankFSRef, kAudioUnitScope_Global, 0,
&outFSRef, sizeof (FSRef));
Here's the stack trace:
