The main thing that AUGraph gives you is synchronized state management, particularly with respect to connections.
If you aren't going to be changing your connections on the fly -- and in a situation like what I'm about to describe, one doesn't tend to need to do this -- you should be able to do something like this:
sources -> mixer -> effect -> output unit
where the effect is implemented as an input callback function on the output unit. To obtain the mixer's output as the effect's input, call AudioUnitRender on the mixer inside the effect processing function.

I currently have 8 audio channels feeding into a Multi channel mixer, then the output from the mixer goes to a remoteIO output.
I would like to grab the audio data after the mixer and place my own effect on it. I tried originally writing my own mixer, then i had acces to the data, but how do i do this in an AUGraph?
I know that the iPod doesnt implement all the fx units you get on the mac, but is it possible to write your own?
thanks
