Hi Everybody

Sorry for this mail abundance but I just can't doing all this by myself.


I've found interesting structure for me in CoreAudio Reference (http://developer.apple.com/documentation/MusicAudio/Reference/CoreAudio/audio_units/chapter_5_section_3.html ) :
it is AudioUnitParameterEvent


So I wrote this code to instantiate the parameterEvent :

		AudioUnitParameterEvent parEvent;
		parEvent.scope		= kAudioUnitScope_Global;
		parEvent.element	= 0;
		parEvent.parameter	= kParam_NoteFreq;
		parEvent.eventType	= kParameterEvent_Immediate;
		parEvent.eventValues.immediate.bufferOffset	= 0;
		parEvent.eventValues.immediate.value			= mNoteFreq;

But I didn't found a AUParameterEventListenerNotify(). Could someone tell me how to notify this kind of event.

Something else how can my Render function interact with my custom view class ? because after all I just need :
AUParameterSet (mParameterListener, self, &parameter, value, 0)
AUParameterListenerNotify (mParameterListener, self, &parameter)
from within the view class.
