M-audio Fast Track Pro 4x4 USB Audio Interface in as new condition with sealed Pro Tools SE software. This interface has had light, non-smoking home studio use over the past few months. The Pro Tools SE software is unopened as I use Ableton Live. This is a very nice interface for the price - the only reason I'm selling it is that I had the opportunity to upgrade to an RME Fireface. $175 + shipping.
