Our software allows users to change the latency associated with the Audio Unit
plug-in, but it seems that Logic is ignoring this change. I have looked all
over, and found others reporting this problem a few years ago, but I don’t see
a resolution anywhere. Here is the code we’re using:
> AudioUnitEvent auEvent;
> auEvent.mArgument.mProperty.mAudioUnit = GetComponentInstance
> ();
> auEvent.mArgument.mProperty.mPropertyID =
> kAudioUnitProperty_Latency;
> auEvent.mArgument.mProperty.mScope = kAudioUnitScope_Global;
> auEvent.mArgument.mProperty.mElement = 0;
> auEvent.mEventType = kAudioUnitEvent_PropertyChange;
> AUEventListenerNotify (paramListenerRef, NULL, &auEvent);
I did find one thread that said they got it working, but it didn’t elaborate as
to exactly *how* they accomplished it other than a very general statement:
> Finally found it. So, you need to manage list of property listeners, and
> whenever this happens ask all property listeners. Ugly, but I spent some time
> looking into the horrible CoreAudio SDK and that's how they do it...
I’m just not sure exactly how that would be accomplished.
Does anyone know how to get this to work in Logic (and any other hosts that
seem to ignore the AUEventListenerNotify() call above)? Got a code snippet?
Thanks,
