What is an Effect in Express?

An effect is a cue or a submaster that can run in a variety of patterns called chases.


Each effect step contains channels. When the step runs, channel level is controlled when the channel is specifically addressed.

An effect can be positive, with lights starting off and being turned on in patterns, or negative, with lights starting on and being turned off in patterns. It can have up to 100 steps, each of which can last up to 99:59 minutes. The effect may be created in Blind or while viewing the steps in Stage. Steps in the effect are individually controlled for level and timing, and the effect is subject to a separate, overall timing parameter
