Focusrite would be my suggestion, but I'd also suggest you get one step up from what you think you need.

There is a (limited) 2 in / 2 out version, but it lacks the Focusrite mixer applet. You don't know you need it until you need it .. then it's too late. Just my 2 cents. I wish I'd have gone a step up on that unit now.

FWIW, I can still run the M-Audio Delta cards on various machines with various OS (Delta is much older than FastTrack), so don't assume just because they say it isn't supported, that it doesn't work. I'd try it and make sure there is an issue before moving on.
You may need to re-install the FastTrack drivers, or 'run as Administrator', or even run in compatibility mode .. but you may be able to run it still. Just a thought.

The Focusrite devices are nice and reliable though if you do need to upgrade.
Sometimes the upgrade is worth the price just to lose the headaches.


I do not work here, but the benefits are still awesome
