Hello, I've recently purchased a copy of Cakewalk's Sonar x1 Producer Edition to try to enhance my skills and move up. Cubase 5 just seemed like it was holding my hand the whole way so instead of upgrading to Cubase 6 I went with this. Anyway My Audio Interface is a M-Audio Fast Track Ultra my operating system is Windows 7 64 Bit Home Premium and I'm having some weird latency issues. I guess its not so much latency, its more of a choppy scratchy sound with about a .5 sec delay. I've messed around with the ASIO/WDM Buffer Size to no avail, as well as tried Asio driver & WDM drive with no result. Does anyone have a clue what this could be? I did a fresh reformat on my computer and got the newest drivers and freshly installed Sonar x64. Every thing was fine over in cubase so im not sure what this could be. If anyone could give any input on the problem I would really appreciate it.
