I have been completely baffled by the loss of my ability to record vocal tracks. I have a Lexicon Omega that worked with my Pro Logic 8 but i'm getting nowhere with it now. What do I need to do to use it? I also have a Presonus 16 4 2 that I would like to incorporate with my I mac and again I'm stumped. My computer skills are next to none and i'm really at a stand still. Please point me in the right direction.
