Apple

Unfortunately it does have to be called from the AU component, not the view.

I tested the AU I'm working on both with and without the begin/end gesture events just now and it seems that automation can only be recorded (in Logic at least) if these events are being sent correctly.

Hope this helps

Nope, still no luck. My code now looks like this:

CAAUParameter* ptrParameter = new CAAUParameter(GetComponentInstance(), iParameterIndex, kAudioUnitScope_Global, 0);

AudioUnitEvent paramEvent;

memset(&paramEvent, 0, sizeof(paramEvent));

paramEvent.mArgument.mParameter = *ptrParameter;

paramEvent.mEventType = kAudioUnitEvent_BeginParameterChangeGesture;

AUEventListenerNotify(NULL, NULL, &paramEvent);

paramEvent.mEventType = kAudioUnitEvent_ParameterValueChange;

AUEventListenerNotify(NULL, NULL, &paramEvent);

paramEvent.mEventType = kAudioUnitEvent_EndParameterChangeGesture;

AUEventListenerNotify(NULL, NULL, &paramEvent);

delete ptrParameter;

Again, all I can think of is I might need to call this from my (cocoa) view component. In which case I do not know how to get the component instance, so before I venture down that road I would love to know if that is necesary.

(I am of course aware I should not call begin and end gesture this often, but when something is not working I prefer to take baby steps in order to locate the problem).

Thanks,

Michael
