LTP (Latest Takes Precedence)
All channels that have been assigned to the Intensity group obey the very simple LTP rule: The
latest value that was set by a function or a slider gets sent out to the DMX universe. This scheme
is useful for intelligent fixture parameters not related to intensity. For example, a gobo change is
expected to happen immediately, regardless of what some other control has done to it. See also
HTP.
Modes
Q Light Controller Plus is based on the common concept of having two distinct operational
modes to prevent accidental or otherwise harmful changes during operation:
Design mode is meant to edit the behaviour of the program; create and edit functions and
fixtures and how they work.
Operate mode is meant to execute the created functions that eventually control the user's
lighting fixtures.
Output plugins
DMX output is achieved thru output plugins that can support one or more output lines. It is also
possible to run QLC+ without actual DMX hardware.
Output (line)
An output is a physical output line provided by a hardware device which is accessed thru an
output plugin. In other words, it is a real DMX universe, but has been dubbed output to separate it
from QLC+'s internal universes. You could think of them as individual XLR output connectors in
your DMX hardware.
RGB Matrix
An RGB matrix function can be used to impose simple graphics and text on a matrix (a grid or a
wall) of RGB and/or monochrome fixture heads. The RGB matrix function has been designed to
be extendable with scripts that can be written by users.
Each RGB matrix has its own speed settings:
Fade In: Time to fade each pixel ON
Fade Out: Time to fade each pixel OFF
Duration: The duration of the current step/frame
RGB Script
An RGB script is a program written in ECMAScript (also known as JavaScript) that produces the
necessary image data for RGB Matrix functions. Learn more from the RGB Script API page.
Scene
A scene function encapsulates the values of selected channels owned by one or more fixture
instances. When a scene is started, the time it takes for its channels to reach their target values
