I'm using fireface 800 with Samplitude v9 on a vista home premium os laptop. I can't get channels 1 & 2 to route. Channel one (set to front and back) works with the instrument input but not the TRS. I'm guessing it's an easy fix but don't have a clue what to do. Any help is appreciated. Also a URL for a good OS optimization webpage would be cool. Thanks.
