Memory-based consoles have become very popular in almost all larger installations, particularly theatres. This type of controller has almost completely replaced preset consoles as controllers of choice. Memory consoles are preferable in productions where scenes do not change from show to show, such as a theatre production, because scenes are designed and digitally recorded, so there is less room for [[human error]], and less time between lighting cues is required to produce the same result. They also allow for lighting cues to contain larger channel counts due to the same time savings gained from not physically moving individual channel faders.
Many memory consoles have a bank of faders. These faders can be programmed to control a single channel (a channel is a lighting designer's numerical name for a dimmer or group of dimmers) or a group of channels (known as a ""submaster""). The console may also have provision to operate in analog to a manual desk for programming scenes or live control. On more advanced consoles, faders can be used to control effects, [[Chase (lighting)|chases]] (sequences of cues), and moving light effects (if the console can control moving lights).
