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?
