I'm trying to get my mic input to play over the itunes play list playing in the background. It's for a sporting event. I want to keep music playing will i provide some commentary on the side. Any help?
If you're using a separate microphone and a digital-audio interface, you can do this with JackRouter (http://www.jackosx.com/). Route your iTunes outputs and your mic to Max ins in JackRouter, and you'll be able to run two separate audio channels in Max.
