I am currently using Pro Tools LE 7.4 with a Digi 003 on a Mac Pro (2.66ghz quad; 4GB Ram). My was using a Roland XV-88 but found that it's hum and buzz was intolerable, so I bought the XV-5050 which has all the same sounds, but an optical out. Before I set out on my current project I need some answers to the following questions: - if i set the Digi 003's clock to Optical when recording from the Optical in, do I have to set the clock to Optical for all the other tracks in the same session too? What are the reprecussions of this, if any? - - is it possible to adjust the optical gain going into the digi 003? Some of the patches I play just aren't loud enough. - Pro Tools is only letting my tracks from the optical in be stereo tracks. Is there a way to ammend this? - how do you turn a stereo track into a mono track? - what is the proper way to pan a stereo track in the mix?
