Another Question on PC-Recording

It sounds like a synchronization issue.
Cubase v2's main got upgrade form v1 that's supposed to fix any problems with synchronization, so if you update your nuendo, it might adress exactly your issues.

I have another question, though:
In Cubase, when you turn on the track monitor , you get about 600 miliseconds of delay between what you are playing and what comes out of the speakers.
I suppose it's because some sort of buffering, does anybody know how to lower the values?
