Feature
A feature is a controllable characteristic of a fixture that is designed to be varied from cue to cue.
Each feature has a predefined name, and can be set to a range of integer values to manipulate it. Many
lamps have a feature called Dim, which controls its brightness. Fancier fixtures may have additional
features such as Color, Pan, Tilt etc.
Feature Preset
A feature preset is an object containing a list of feature names and values, not bound to any particular
fixture. Feature presets are created by selecting a fixture in the cue editor, setting up the desired set of
features (and clearing all others), and then storing that set of features as a feature preset. They are then
used by adding them to fixtures within a cue. Any features of those fixtures that are listed in the
feature presets are given those values; if the presets are then modified, all cues that refer to them
automatically change.
This, for instance, allows one to define a particular point in a stage coordinate system, and store the
Pan and Tilt features that represent that point as a feature preset. If can then be applied to any fixtures
that use that stage focus coordinate system, to direct those fixtures to that point. Doing the same with
a regular preset would involve setting up the same Pan and Tilt features for each fixture individually.
Like regular presets, feature values specified directly in the cue override values inherited from feature
presets. When a feature preset is stored over another one, the user has the option of merging them,
which allows feature presets to be constructed with combinations of features that aren't found in any
single fixture.
Fine
The Fine switch is a toggle switch that determines the scaling of the rotary controls for some features.
If Fine is on, each rotary control increments or decrements its corresponding value by a single count
for each step in the control. If Fine is off, some features step through a limited sequence of values; for
instance, Color features step through solid colors, and Gobo features step through properly-aligned
gobo wheel positions. Other features step by small increments up to a point, and then step by larger
multiples to span the range more quickly; changing direction resumes stepping by the small
increments, so that one can home in on a value without turning on Fine. Usually the small increment
is one, but for Pan and Tilt, which have a 0..9999 range, it is larger, yielding three different steps
sizes.
Fixture
A fixture is any controllable device attached to the CP-100, or the software object that represents that
physical device. Each fixture in the stage setup must be represented by a fixture object in the software
system. When a fixture object is created, the user assigns it an arbitrary unique number, and
optionally names it to assist in keeping track of what fixture is what. The user specifies the
characteristics of each fixture by choosing a fixture type from a list of types supported by the CP-100.
Fixture Type
A fixture type is an abstract description of the characteristics of a particular kind of fixture. Complex
fixture types are generally identified by brand name and model; the simplest fixture is called Dimmer,
which is a lamp whose brightness is the only controllable feature. When a fixture object is created to
represent a physical fixture in the stage setup, the user must specify a fixture type, which defines how
