When recording with Cubase LE 1.0.18, there are these periodic "clicks and pops". Actually, they are more than clicks and pops, as they send the levels to peak and they seems to last longer than usual clicks and pops. I thought maybe my laptop and Fast Track Ultra were not in sync, but they sure appear to be. Tried all kinds of settings changes, changing USB port. Any ideas what could be causing these noises?
