Dimmers.

Since dimmers have only one feature, the CP-100 treats them separately from
fixtures. This allows up to eight of them to be controlled by the rotaries at once.

Dimmer fixtures. You can also treat a dimmer as a fixture, in which case it looks like any other

fixture, except that it has only one feature, called

Di

m. The type name,

naturally, is

Dimme

r. In general, though, it is preferable to treat dimmers as

distinct from fixtures.

Generic DMX fixtures.

These are fixtures that have an adjustable number of features (up to 32),
and no special semantics other than that one channel may be designated
as a dimmer channel. A generic DMX fixture is useful for quickly trying
out a new fixture type, without having to build a new library entry. Its
type name is

DMX Fixtur

e.

DMX pass-thru fixtures. These pseudo-fixtures continuously copy a contiguous range of channels

from the DMX input to one of the DMX outputs. They are created like
regular fixtures, but since they have no features, they do not appear in
any cues, and cannot be manipulated during performance. Their type
name is

DMX Pass Thr

u.



Sample Fixture

Here is that example of a simple fixture from the standard library again:

vendor Clay Paky
type MiniScan
channel Color
steps 0 16 33 50 66 82 98 114 130
channel Gobo
master 127
htp
dbo
clear
hilite 128
steps 255 -68 -127 155 175 195 215 235 255
channel Pan
channel Tilt


The indenting is ignored by the CP-100, but makes it easier for a human to read the library. The

Color

and

Gobo

features are accessible under the

Color 1

and

Gobo 1

commands, even though

the

color

and

gobo

parameters weren’t specified, because the CP-100 recognizes those feature

names. For the

Color

feature, the rotary stops on the specified values, plus 255 (since it always

stops at the minimum and maximum values). For the

Gobo

feature, the rotary stops on zero and on

the specified values, including 68 and 127, but the

Gobo

command skips the values of zero, 68 and

127.

The only reason the

Gobo

feature has so many parameters is that it is an atypical gobo channel,

acting as a shutter and a strobe as well for this particular unit. The

Pan

and

Tilt

channels work as

expected because the CP-100 recognizes those names as well. Of course, the best way to familiarize
