Why have my Pan knobs turned into volume knobs? [SOLVED]

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. 

do you have a bus solo'd? and see if the volume or pan are added to any groups.

Nope,  no buses are soloed - nor do I have any groups set up (just checked the group manager). 


It's basically as if the master bus is outputting the left side only through both output channels. Both of the master fader lights are moving in unison. If I toggle the interleave button on the master track, there is no difference to the sound. So what appears to be happening is that the master channel is not receiving the right channel any more. If I solo a track and pan it all the way to the right, the right meter on that track is showing an output. But the master track is showing no output.  

If I load the project in safe mode and choose not to load any plugs, then insert a new synth track,  the panning is working properly. 

save as a new project or cakewalk bundle and open. what then? midi pan or audio track pan??

any plugs on the track? is it a synth output or an audio track output??

Glad to hear that you figured it out....can be very frustrating for sure...!

I would like to make a correction to my above statement about Guitar Rig. It's not so much that it's ridiculous that it opens in mono by default, it's that you have to open an instance of the freaking thing to use any NI effects in the first place. Hopefully with their recent upgrade of the Vintage Compressors to standalone versions, they might get around to doing the same with everything else as well. 

Are you sure? Because I think there is a bug whereby the meters at the top show a stereo input even when it's in mono. When you open it, only the "L" is activated (the L and R next to the input meter). You have to activate the "R" as well to make it stereo. I've heard quite a few people complain that it opens in mono. 

sharke, Super glad you solved this and no apologies needed.  This was an interesting thread.  It is always helpful for all of us to think through such problems.  Who knows?  One of the wrong solutions above may be the right one for someone else.
