Don't know what I did, but I lost my piano track in my mixer. It's still there in the arrange window and plays in my arrangement, but I can't adjust the volume because it's not in the mixer. What can I do the get it back? Also, my first track is an Alto sax and it's there in the arrangement window, but in the mixer it's listed a inst 1. Don't know why either. Is there a way of renaming it in the mixer as Alto 1? Thanks.
