Hello Brian,
Thanks for the reply. I think this is on the right track however "myTimerName" is undeclared. This is not my timer, it is from the AUSampler plug-in.

However, when I close the component and the cocoa editor window, I start to get a non-stop serious of console messages as seen below. I have narrowed it down to Apple's AuSampler and seems to be coming from a timer procedure that was not removed. So I am pretty sure there is a deficiency in my program when it comes to fully disposing of a core audio, cocoa-based audioUnit. Can anyone please stir me in the right direction?
