Logic 9 problem: I have this project I'm working on and the pan knobs in the mixer are acting funny. If I put the bass track in the center of the pan I lose the volume. If I put it left or right I get the volume back this is the same in other tracks as well. What have I done wrong and how can I fix this? The pan knob is not panning anything just messing with the volumes. I have searched google all day and could not find an answer. ( I work a lot in the score editor.) but sometimes use the piano roll editor. This project used both. Mac book pro 10.8.2 .
