Moving Light Programming Chapter Four 85
LP-X24 and LP-X48 Users Manual
Because of the limitations in the pan and tilt mechanisms, the area that a moving mirror
can light is restricted.
Instruments such as the Mac 500 and Studio Color, on the other hand, are moving head
or true moving lights. These instruments are less restricted in their range of movement
but use all of the features of the LP-X Moving Light Controller software as a moving
mirror instrument would.
No Change
On the LP-X, there is an important feature known as No Change . This is referred to as
Transparency in some moving light controllers.
Moving light programming requires that each light in a look be assigned values for the
four properties described above—beam, color, focus and intensity.
There may be instances where you want the light to retain the value of whatever
precedes it. This is accomplished by setting the light to
No Change .
For example, you know that the playwright will walk on stage for a bow in a specific
location but you do not know when it will happen. You want to light the playwright using
the same colors that are currently in use on stage. You create a look that includes a
specific value for the beam, focus and intensity. You set the color value to
No Change .
When the playwright walks on stage, you play back the look. The light moves into the
prearranged position with a specific beam and intensity

but the color is whatever was
last specified for the light.
No Change applies to color, beam and focus. It does not apply to intensity.
The Moving Light Library
The LP-X includes a library of the moving light fixtures that are in common use. Because
of this library, the LP-X "knows" all of the basic information about a light

and you don't
have to program it in. The basic information consists of the following:
1. A list of the attributes for the fixture and the property with which each attribute is
grouped. For example, the Intellabeam 8 Channel has eight attributes.
Attribute Property Affected
Color Wheel 1 Color
Shutter Beam
Gobo Wheel 1 Beam
Iris Beam
Speed Beam
Pan Focus
Tilt Focus
Dimmer Intensity
