Are you still working on this issue? I have fairly conclusive proof that Cubase LE is the problem. I can use my Firestudio with Cakewalk Sonar on my desktop. It works fine. Next, I downloaded a shareware DAW called Reaper. Set it up and it recorded the first attempt. I can see signal in both DAWs and they both record just fine. This is strong evidence that Cubase is the issue here. I would like to know if you guys are even working on this issue or not. Otherwise, I'm going to dump Cubase unless you guys come up with a solution to this issue. I was really hoping Cubase worked, as I am in the process of deciding whether to upgrade Sonar or switch to Cubase. If LE doesn't work with my interface, how can I expect any other version to work?
