Effects can be viewed as an extra attribute, however unlike the other attributes, Effects do not directly control parameters of the selected fixtures. Instead, effects are used to manipulate parameters to create effects such as “Circle”, “Ballyhoo” and “Rainbow”. This is achieved by applying various mathematical functions (sine, cosine, ramp etc) to the outputs of different fixture parameters and adjusting the size, speed and offset values.
Using this, a wide range of movement and other effects can be generated quickly and easily. Effects can affect any parameter, from any attribute, and can also control multiple parameters from multiple attributes.
