Thanks for the info on this. This was one of the first questions that came to mind when my FM3 arrived last week. I have to get ready for some gigs and need to playback tracks from my phone through the FM3 and practice along to the track w/ my headphones so I'm not disturbing the wife and kids. I also use iReal Pro a lot as well. Looking forward to giving the USB approach a try later today.
Cheers,
