Moving Light: A special class of light fixtures that have programmable properties. Unlike
conventional lights (dimmers) that have only the property level, moving lights have four
properties—color, beam, focus and intensity.
Moving Light Cue: A Moving Light cue (ML cue) is a specific static look on stage. A cue is the
product of specific settings for each of the attributes for all instruments in the system.
No Change: In moving light programming, a label or attribute setting specifying that the cue
should not change from the value or values in the last cue. In the following example, the color
for CUE_002 would be red because the preceding cue has the color red.
CUE_001 RED
CUE_002 NO CHANGE
CUE_003 BLUE
If the setting for the color in CUE_001 were changed to blue, the color in CUE_002 would also
change to blue.
Also known as transparency.
Personality: The mapping of parameters to DMX channels is accomplished by an instrument
database that is factory defined and is extensible by the user. The response of the instrument to
DMX data is determined by its personality, which is stored in the LP-3000 database.
Pile-On: See Highest Takes Precedence.
Playback: The faders on the LP-3000 that control entire scenes of conventional instruments as
well as chases and ML chases are called playbacks. Their function is to bring scenes back from
memory on demand. In the LP-3000, all 18 playbacks can be used at the same time.
Preset: See Scene.
Preset Scene: See Scene.
Prism (Beam Property): The number of elements that can be introduced into the optic path is
limited only by the imagination of instrument designers and the budgets of the users. Besides
the standards of gobo and color, several popular instruments incorporate another general-
purpose wheel for effects. Such effects can include prisms to split the beam.
Rotating Gobo (Beam Property): Another special effect is the ability to rotate a gobo pattern.
This is not to be confused with spinning the entire wheel. Still another stepper motor is used to
rotate the individual gobo in its position on the gobo wheel. Usually another control channel is
used to set the rate and direction of the rotation.
Scene: Historically, a bank of faders—one fader for each board channel. When referring to
memory boards, usually means a stored pattern that contains the level for each board channel.
Scenes are the basic looks that a designer produces on stage.
Sequence: A sequence is a chain of moving light cues, executed in order with a single event
trigger.
Shutter (Beam Property): To produce a fast blackout, a mechanical shutter is used that blocks
all light output very quickly. Opening and closing the shutter rapidly is used as a strobe effect.
Split Dipless Crossfade: See Crossfade.
