How to get MIDIThruConnection to the "built-in endpoint"?

Okay, admittedly I've not grokked all there is to know about core audio and midi. I'm doing my first Core Audio project. Here's what I'm trying to do:

	track --> myEndpoint --> built-in synth

Or, this (a Y-connector):

	track --> myEndpoint
	  |
	  +-----> built-in synth

I'm trying to use MusicPlayer to push midi not only to the sequence's AU graph for the Mac's built-in synth (which was quite easy to setup, thanks), but ALSO to an endpoint. The endpoint looks at the notes and does something interesting with it, as the song plays.

I understand from example code (SimpleSDK/PlaySequence) that's its either one or the other, not both. So, I figure I'd be all set if I could determine how to add my endpoint some how magically into the AU graph, or better yet, using MIDIThruConnection I could use my endpoint as a passthrough. However, to use MIDIThruConnection I need to pass the midi along the chain to the built-in synth. But, there's the rub... is there such an endpoint to be found?

How do I glue this together?

Thank you,

/Jay
