«  what I needed »

For the technical aspect, see the site m-audio
I had a mobile interface
The case is robust but I have doubts about the strength of knob '(plastic) although they support multiple transports for over a year

I use it mainly with Guitar Rig 4 when I have not the opportunity to play at home and taken for guitars

UTILIZATION

Memory, the drivers are not updated regularly.
I'm using ASIO4ALL instead, it gives me a latency of 8ms

GETTING STARTED

The installation is plug and play. No problem.
After that, it only remains to choose the sample rate

I have, from time to time, a problem of recognition Guitar Rig. A reboot and make sure it works ... hard to tell if the crash comes from the card, soft or my old pc

The manual is very concise but good enough given the ease of use of the Fast Track Pro

OVERALL OPINION

It's been over a year I use it and I'm really not disappointed. I have not tried other brand or model of competition.
I love being able to slip it into the cover of my guitar and settle down anywhere.
At that price, quality is the appointment
