There is a new Fast Track Pro driver for Win 7 x64 in beta. You have to sign up to get it. The process is explained in the M-Audio Forum. I am using it and getting better ASIO performance. Worth a try if you are interested. Also, with a new computer you should go into there and clean out any garbage that is installed by the manufacturer. Often, there are a ton of resident programs running at start. Software that is checking for updates even when you aren’t using the program. Programs that are waiting for you to press a button or plug something in and then it automatically responds, etc.
