ok, here is a track with the pan centered… er.. I guess it’s a little to the right…. but close enough
Here is a track panned all the way to the right:
notice the bass lead track shows only right signal, but the master volume has gone all the way down. I can hear nothing.
and here it is panned all the way to the left:
Now the bass lead track signifies only left signal, and the master is back up. I can hear it…. but in both the left AND the right.
