One of the great developments of fader use on automated lighting consoles is the ability to use the faders to adjust playback settings instead of fixture parameters. When a playback is built with effects or is a chase, you can often assign the associated fader to adjust the speed of the chase or effect. This is an extremely powerful tool that lets you dynamically adjust changing looks at any time. I like to build a ballyhoo look and assign the correlated fader to a rate control. This way I can use the same movement slowly for a ballad, or fast for a big rocking chorus.
