Paul P Good one, Felix. Now we know why the PC76 makes noise even when it receives no input.
konradhThe next time someone starts an argument about whether Sonar or ProTools is better, mention this feature. That should end the discussion.
dlesauxIt's an Easter egg, it turns the backlight on the PC4K buss compressor as Scook already pointed out, that's it.. To the best of my knowledge, it does nothing on the PC76.
