Well any audio interface should have proprietary asio drivers or dsp clocking to lower latency. I can't imagine that being too much of a problem unless youre trying to use a good little chunk of effects in a live scenario.
That said....dont get a fast track. Yes....it works, but there are at least 2 better interfaces at the exact same price: Presonus Audiobox & Focusrite Scarlett. Both have better preamps and a/d convertors then the fast track, as well as just better overall construction (not made of plastic). The scarlett would be my choice of the 3 because it has the most natural, warm, and clean sounding preamps of the bunch.
Noteably though the scarlett doesnt have midi in/out, So if you need to hook up a midi only device like an old keyboard or something then go for the audiobox.
Believe me, I test and sell this shit for a living.
