I have produced an album and dozen of releases with this one. I have also done few dozen digital dj gigs using Traktor and this little beast as my sound module. Sound quality is excellent and recording is really good too.
5 start product if you ask me!
One and only interface I use for recording, it's served me well these past several years. Bought it from my friend Shawn who was looking to get rid of it (and his Pro Tools M-Powered 7 which I never use). Might upgrade to a tube-driven interface at some point and see what it sounds like in comparison, but the Fast Track has been a total workhorse since I got it.
I've been using the Fast-Track pro for about 3 years now and its been an amazing ride. Its lightweight, small and powerful. I use it in my studio for recording vocals, guitars and any other acoustic instrument. Its an excellent piece of gear.
