I have this gurl who can sing her ass off live and looks good too! the only problem is, it seems like as soon as she steps in the booth she develops pitch issues. Here voice still sounds full and beautiful she jus misses notes that she dosent miss when we're not recording.... WHAT THE HELL DO I DO. I have protools and im thinking about getting a pitch plug in but I have no idea wich one to get... any suggestions? also is there any thing else i can do... thanx in advance
