Hi, I have Studio One 4 Artist, running on an Acer windows machine. Still just learning my way around, and having a ball. I have a recorded Presence track for bass. It used to show in the main screen, and I could edit it easily. Suddenly now it won't show up either in the main screen or as a channel in the Mix view, but I can hear the recorded track with no problem. How can I get it back to showing again? I know it's something easy and obvious, but I just can't figure it out. I had it showing until suddenly I didn't... Suggestions welcome. Thanks!
