Gamers have traditionally used joysticks for controlling games. It is a device that allows control of two different axes simultaneously. Certain synthesizer manufacturers have utilized the principle instead of using separate modulation and pitch wheels, but the main usage of the device is now beginning to appear in surround sound production. Pan pots are two- dimensional devices (left/right,) and since surround sound requires at least four points to define an audio source location (left/right/front and left/right/rear,) joysticks are a common feature on surround consoles and control surfaces.
