# Fixture Definition Editor

Fixture Definition Editor is a separate application bundled together with QLC+ for creating and modifying fixture definitions used by QLC+. The definitions tell QLC+ (and users) important details about fixtures, such as which channel is used for pan movement, what value in which channel changes the beam color to green, how the fixture is reset etc...

The main window in the Fixture Editor is just an empty workspace that contains the actual editor windows used to edit fixture definitions.

Important note: for many reasons, you SHOULD NOT save or copy your custom fixtures in the QLC+ system fixtures folder. The most important is that when you uninstall QLC+, the system fixtures folder gets deleted, so your fixtures.
You are recommended to save them in the user fixtures folder. To find it, please refer to the Q & A section of this documentation.

## Main toolbar

| Create a new fixture definition. Opens an empty Fixture Editor window.
| Open an existing fixture definiton. Opens the fixture definition in a Fixture Editor window.
| Save the fixture definition in the currently active Fixture Editor window.
| Save the fixture definition with a given name in the currently active Fixture Editor window.

# Fixture Editor

Fixture Editor windows contain everything needed to edit one Fixture Definition at a time. The windows are separated in five tabs: General, Physical, Channels, Modes and Aliases.
Tabs are organized in a logical order that should be followed from left to right when creating a new fixture definition.

## General Tab

This is the section where the Fixture general information is provided.

Manufacturer | The fixture's manufacturer name. For example "FooCompany". Please note that if you're adding a definition of a manufacturer already present in the QLC+ library, you should adopt the same exact name adopted by the other creators. For example, "IMG Stageline" is not "img stageline" or "IMG-Stageline"
Model | The fixture's model name. For example "FooZapper 2000". Please stick to the product manual to fill in this information. No need to specify the LED configuration like "PAR64 MKII 8x1W LED RGBWAUV USB". It's just "PAR64 MKII"
Type | The fixture's category type. For an accurate preview, it is important to fill in the proper category. For example, while a moving head is most likely a color changer too, the type should be set to "Moving Head"
Author | The fixture definition author name. Please do not submit email addresses or references to some website. They will be removed anyway during review.

## Physical Tab

This is the section where the global physical information of the fixture is provided.
An identical section is also present in each mode, in case the fixture allows its physical properties (e.g. pan/tilt range) to be altered depending on the mode. In that case, the global physical information can be overridden by per-mode physical information.

Bulb | Type: The type of the actual light source within the fixture. Lumens: The light source's total luminous output in lumens. Color Temperature (K): The light source's color temperature in Kelvins
Lens | Name: The type/name of the lens, if applicable. Min. degrees: The fixture's minimum beam angle in degrees. Max. degrees: The fixture's maximum beam angle in degrees.
Electrical | Power Consumption: The fixture's total power consumption in Watts. DMX Connector: The type of the fixture's DMX connector.
Dimensions | Weight: The fixture's total weight in Kilograms. Width: The fixture's total horizontal width in millimeters. Height: The fixture's total vertical height in millimeters. Depth: The fixture's total depth in millimeters.
Head(s) | Type: The method of focusing the beam on different areas. For stationary fixtures this can be set to Fixed. Pan Max Degrees: The maximum pan width in degrees. Tilt Max Degrees: The maximum tilt height in degrees.

## Channels Tab

The channels tab contains all possible channels that the fixture understands in all of its modes. The channel order doesn't matter in this tab at all. Instead, channels are arranged in certain order in each mode in the Mode tab. On the Channel tab, only the channel names, their capabilities (i.e. value ranges and their purpose) matters.

| Add a new channel to the fixture using the Channel Editor
| Remove the selected channels from the fixture and from all modes
| Edit the currently selected channel using the Channel Editor
| Copy the currently selected channel to the clipboard. Channels in the clipboard can also be pasted to other fixture definition windows
| Paste a channel from clipboard to the fixture definition. Channels in the clipboard can also be pasted to other fixture definition windows
| Expand or collapse all the channel nodes in the channel list

### Channel Editor

The Channel Editor is used to edit individual channels and the DMX value ranges of each capability (a green color, a certain gobo, prism rotation, etc.) that a fixture channel provides. Refer to your fixture's manual to get a detailed list of the fixture's channels and DMX values.

Here's a few screenshots showing the possible scenarios that can be encountered while editing a Fixture channel.

Fig. 1 | Fig. 2
Fig. 3 | Fig. 4

Following, the description of the settings that appear in the Channel Editor. Reference to the above figures will be done to point you to a visual context.

Name | The channel name. When selecting a channel preset (single capability channel), a channel name will be automatically suggested, with the possibility to customize it.
Preset | A preset is a sort of shortcut to speed up the definition creation. It also provides to the QLC+ engine, useful information to recognize and properly treat a DMX channel. It frequently happens that a Fixture has some RGB or CMY channels. A LED bar might have dozens of them. Therefore, selecting a color preset will fill in for you all the necessary information that QLC+ needs, with a single mouse click. (See Fig. 1) It is also frequent to find a channel to control Pan/Tilt speed. Some presets are available for that purpose, indicating also if the speed is from slow to fast or from fast to slow. Just pick the preset that is more suitable for the definition you're creating. When a preset is selected, all the rest of the editor become inactive. If a channel has multiple DMX ranges (capabilities), just leave "Preset" to "Custom" and proceed further with this reading.
Type | This indicated the channel's type (its role in the fixture). Selecting a type, implicitely defines also the channel precedence (LTP or HTP). It is therefore very important to pick the correct type here, to avoid undesired behaviours within QLC+. All the intensity/color channel types obey to the HTP rule: Intensity, Red, Green, Blue, Cyan, Magenta, Yellow, White, Amber, UV, Lime and Indigo. All the other types obey to the LTP rule: Beam, Color, Effect, Gobo, Maintenance, Nothing, Pan, Tilt, Prism, Shutter and Speed. Intensity is used for dimmer / master dimmer channels. Primary colors (Red, Cyan, White, etc) are used to control single color channels. Please do not confuse these types with the "Color" type (see below) Note that the Grand Master controls only Intensity and primary color channels by default. Note also that the Color Tool in Scene Editor is available only if a fixture provides Primary color channels for RGBAWUV/CMY. The Color type is used to control a fixed color wheel or pre-defined color macros. Don't assign individual RGBAW/CMY color channels to the Color type but instead use the primary color types as described above The Gobo type is used to control gobo wheel position or indexing. The Speed type is used to control something related to speed (gobo rotation, rainbow speed, tracking speed). The Prism type is used to control a prism. The Shutter type is used to control a shutter, a strobe or an iris. The Beam type is used to control a beam shaper (such as a zoom feature). The Effect type is used to control something that doesn't quite fit into any of the other groups. The Maintenance type is used to control feature such as resetting or a cooling fan or something similar. The Nothing type is used as a channel spacer or a place holder. Some channels of this type might be replaced with the alias feature. The Pan and Tilt types are used to control Pan/Tilt (or X/Y) features of moving heads or lasers
Default value | Specify the DMX value (0 to 255) to which a channel is set on power up. For example, some moving heads position their Pan/Tilt motors half way, which means the initial DMX channel value is equal to 127.
Role | Applicable to channel pairs that make 16 bit values, usually Pan or Tilt group, but some newer fixtures support 16 bit dimmer or even RGB, gobo or focus channels. For 8 bit values (e.g. when the fixture supports only 8bit movement, only one channel for each movement), assign the Coarse (MSB) control byte to the channel. If, however, the fixture supports 16bit (two channels for each feature), you should assign the Coarse (MSB) byte to the channels that provide coarse value and the Fine (LSB) byte to the channels that provide fine value adjustment. If you are not sure, use Coarse MSB.
Capabilities | Displays the list of DMX value ranges for the currently edited channel. If a channel provides only one capability (for example pan or dimmer) you should use a channel preset (see above). For more elaborate capabilities, such as colors or gobos, you should create capability ranges for each of the colors (for example 0-15 white, 16-32 blue...). Specific ranges for each channel can be found in the product manual under the name "DMX chart". Entering DMX ranges is pretty straight forward. The entry area is organized as a spreadsheet where range values and descriptions can be entered continuously just by pressing the TAB key.
Preset | Each capability can be enriched with a so called "preset", which tells the QLC+ engine more useful information about a range of DMX values. For example if the capability is "Shutter open", a preset called "ShutterOpen" is available so that QLC+ knows exactly how to treat the range. Depending on the preset type, one or more additional information could be entered: ColorMacro: allows to pick a single color used tyipically on color wheels ColorDoubleMacro: allows to pick two colors to represent an intermediate position of a color wheel (Fig. 3) GoboMacro: allows to select a gobo picture to be used when entering the capability range (Fig. 4) StrobeFrequency: allows to enter a precise frequency (in Hertz) for a strobe feature StrobeFreqRange: allows to enter 2 values (minimum and maximum) to represent the range of frequencies (in Hertz) to simulate a strobo effect (Fig. 2) Alias: This is a special capability preset to indicate that when in this range, an alias should be triggered. An alias is a replacement of a channel. See the Aliases tab to understand how to define aliases
| Remove the selected capabilities from the channel.
| Create new capabilities quickly with the capability wizard.

### Capbility wizard

Capability Wizard is a handy tool for creating multiple capability value ranges of the same size. Usually this applies to fixed colors, gobo indices and various macro channels.

Start | The starting value for new capabilities. Sometimes there might be other capabilities at the start of the channel's value range that you can skip by adjusting this value.
Width | The size of each value range.
Amount | Number of capabilities to create.
Name | The common name for each capability. You can use the hash mark # to denote a place for an index number (i.e. "Gobo #" creates Gobo 1, Gobo 2, Gobo 3...)
Sample | Every time you change a parameter in the wizard, this list is updated to show you a sample of what kinds of capabilities will be created once you click OK.

## Modes Tab

The modes tab contains all modes the fixture can be configured to.

Mode list | Displays all modes for the currently edited fixture. Each mode item can be opened to display the set and order of channels in that mode. Name: The name of the mode (each name must be unique) Channels: Number of channels in each mode Heads: The number of light sources each mode supports
| Create a new mode for the fixture, using the Mode Editor.
| Remove the currently selected mode from the fixture. Removing a mode does not destroy any channels or other modes.
| Edit the currently selected mode, using the Mode Editor.
| Create a copy of the currently selected mode to the same fixture. Since modes are tightly coupled to a certain fixture's channels, modes cannot be copied across fixtures.
| Open or close all mode items.

## Aliases Tab

In this tab it is possible to define the rules of replacement triggered by capabilities set as "Alias" preset.
Let's make an example. A fixture has channel 5 named "Effects" which controls the behavior of channel 6. Channel 5 has 2 capabilities: "Speed on channel 6" and "Sound sensitivity on channel 6". The latter have been set to the "Alias" preset. By default, when DMX value of channel 5 is 0, channel 6 acts as speed control. When DMX value of channel 5 enters the "sound sensitivity" capability, channel 6 becomes a sound sensitivity adjustment.
To cope with this case, you need to define 2 channels: "Speed" and "Sound sensitivity". In the fixture mode add only "Speed", since it will the default behavior when DMX value of channel 5 is equal to 0.
Then you need to define just one alias: the one that will replace the default channel "Speed" with "Sound sensitivity". QLC+ will then know what to do when the DMX value of channel 5 enters or exits the alias.

Alias | Shows the list of all capabilities of all channels set as "Alias" preset. The string is in the form [Channel name] - [Capability name] [DMX value range]
In mode | Select the mode where the alias must have effect
replace | Select the mode channel to be replaced when the alias is triggered
with | Select the channel that will substitute the "replace" channel when the alias is triggered
| Add the triplet In mode X, replace Y with Z to the known aliases list
| Remove the selected alias from the aliases list
