Jog Wheel
The round wheel on a controller or CDJ for tempo and position.
Detailed explanation
The jog wheel is one of the most important controls on a DJ controller or CDJ. It has two functions: 1. The top plate (vinyl mode): stop the track and move it back and forth by hand — the basis of scratching. 2. The rim: a short turn forward or back gives a pitch bend, a brief tempo change with no lasting effect. The rim is what you use for phase alignment when beatmatching.
In practice
The jog wheel does two completely different things depending on where you touch it. On the top plate you grab it like vinyl and hold or pull the track — for that, vinyl mode has to be on. On the rim you only push the phase forward or back a little without stopping playback. Anyone who accidentally grabs the top while correcting brakes the track and turns a small offset into an audible mistake.
