rotary is moved, all the values jump to the value of the lowest-numbered fixture, and being moving in
tandem from there.
Rotaries may also be used to control dimmers, in which case the display shows up to eight of the
dimmers in the cue editor at a time. They are also used to control Stage Focus coordinates, and to
adjust the rate of chase and macro playback in the submasters.

Solo Mode
The Solo switch contains an LED which indicates solo mode, and is toggled on and off when the
switch is pressed. When solo mode is off, invoking cues with the Go switch adds the cue to whatever
is in the cue editor; any conflicts are resolved by taking the highest value for brightness features and
the new value for other features. When solo mode is on, invoking cues with the Go switch implicitly
clears the cue editor first, so each invoked cue controls the stage by itself (assuming the fader control
sources are all the way off, that is).
Stage Focus
This is an option provided by steerable fixtures that allows their Pan and Tilt features to be remapped
into an arbitrary coordinate system defined by four points on the stage. Once Stage Focus is turned
on, the Pan and Tilt feature values refer not to the absolute position of the mirror in the fixture, but to
coordinates within the four-sided area defined by the four points. Actually, the area within the four
points is accessed with Pan and Tilt values that range from one quarter to three quarters of full scale
(usually 64 and 192 on a scale from 0 to 255), which means that it is still possible to position the
fixture somewhat outside the four-sided area, although the result may run into the physical limits of
the fixture.
The virtue of Stage Focus is that when a show is moved to a different stage with different dimensions,
the only thing that needs to be changed are the Stage Focus coordinates for each fixture, not the
potentially huge number of Pan and Tilt feature values in the cues. The coordinates are stored as eight
attributes of the filter (called P00, P01, P10, P11, T00, T01, T10 and T11), although one doesn't have
to set these attributes blindly. Instead, a display is provided that connects the eight rotaries to these
attributes, and points the fixture to the appropriate corner whenever one of them is moved.
Stage Focus is enabled on a per-cue, per-fixture basis. That is, a fixture can be directed to a particular
spot using stage coordinates in one cue, and then absolute Pan and Tilt values in another.
The stage focus capability is an alternative to the preset capability. Presets are useful where lights
need to be positioned on specific points on the stage, points that may not maintain any particular
geometric relationship to each other from venue to venue. Note, however, that if both are used, the
presets will contain coordinates that are then translated according to the stage focus. For Stage Focus
to work properly, however, both the Pan and Tilt features must come from the same source. That is, it
is not legal to supply the Pan feature from a preset and then override just the Tilt feature in the cue
itself.
