If you need any additional information on Pro Tools and it's quirks (and there are more than a few), head over to the Digidesign user's forum at There are many helpful people on that forum that would be happy to answer any questions. If one set of inputs is being used, it may cancel the other set. If your monitors have multiple inputs, (say 1 pair of 1/4" and 1 pair of XLR) use one pair coming from the 003 and another pair coming from the Axe-Fx. It would now become part of your Pro Tools session. That way, you're not using iTunes anymore. Import the song (audio file) that you want to play along with into Pro Tools as a stereo audio track. However, there may be a couple of workarounds to your dilemma.ġ. I myself have a 003 Factory and mine won't do this either. Cheaper interface, not as many bells and whistles.go figure. The real goofy thing here is that I believe the Mbox WILL do audio from multiple clients at the same time. Unfortunately, it won't do both simultaneously. So for example, you can choose to run audio from iTunes, OR from a Pro Tools session. Meaning that it can only do audio from one source at a time. The problem lies in the fact that the audio drivers from Digi (Core Audio Manager), is a single client driver. Not entirely sure I'm reading your question right, but here's my answer to how I read it.
