If I start a 5.1 sequence in Premiere CC the mixer defaults to 'read' on all tracks. If I then alter the 'joystick' panner on the source tracks to where I want them and then press play the panned position jumps back to centre. I have to select 'off' or 'write' on the automation for the panned position to stay in correct place. This does not happen on CS6. Is this a feature or bug?
