Been working on this project for a few weeks with no problems. All of a sudden - and I have no idea what happened - the pan knobs on all of the tracks have stopped working properly. Instead of panning the tracks left or right, they're increasing in volume when I turn to the left and decreasing to zero when I turn to the right.
Panning on the master bus works as expected.
I have tried toggling the stereo interleave button on each track. The panning knob works the same no matter how it is set.
If I start a new project and load up a synth, the panning works properly.
What in God's name can I have done to this project for it to completely screw up my pan knobs like this?
EDIT: I should point out that when I pan a track hard right, although the audible volume drops to zero, the right half of the meter is showing an output level.
