Panning, put more simply, is the process where any track is sent to the left stereo channel, the right stereo channel, or both, in some ratio. If a signal is routed equally to both channels, it is said to be panned to center or "down the middle". If it's a little more to the left than the right, it is panned "soft left". If it's only on the left channel, it's panned "hard left". Sometimes, panning is changed during mixdown, with a signal being moved from left to right, as an effect. Of course, this is easier than running back and forth on the stage while you play.-Richie
