Fixture Control

The Fixture Control page provides real-time interactive control over your configured fixtures. You can adjust colors, dimmers, pan/tilt, and other fixture functions directly from the Web UI.

Fixture Control is available on both the touchscreen (Main Menu > Fixture Control) and the Web UI (Lighting > Fixture Control). The Web UI provides additional capabilities including the effects engine and detailed per-fixture editing.

Controlling Fixtures

The Fixture Control page displays all configured fixtures with their current state. Three view modes - Normal, Compact, and Diagnostic - trade detail for density, and the All Settings toggle reveals every fixture function, including ones normally hidden. Select one or more fixtures (see Selecting Several Fixtures) to control them in the pane on the right:

• Color - Use the color picker to set RGB/RGBA values for fixtures that support color mixing
• Dimmer - Adjust the intensity/brightness level
• Pan/Tilt - Position moving fixtures
• Other functions - Additional controls appear based on the fixture’s profile capabilities

Changes are applied in real-time - you’ll see the lights respond immediately.

Selecting Several Fixtures

In the Web UI every fixture has a checkbox, and the checked fixtures are what the control pane drives and what Save as Preset saves:

• Click a fixture to select just that one. Once several fixtures are checked, a click adds or removes that fixture instead, so a stray click never loses the selection.
• Tick its checkbox, or Ctrl-click (Cmd-click on a Mac), to add or remove a fixture.
• Shift-click selects every fixture from the last one you clicked to this one.
• Each zone has All and None buttons, and the header has Select All and Clear. Esc clears the selection.

The pane title tells you what it controls: Control - Bar (8) when the selection is exactly one zone, or Control - 5 fixtures otherwise. A change in the pane goes to every selected fixture at once, faded too when Fade is on.

Which controls the pane shows depends on what the fixtures have in common:

• Intensity and color (red, green, blue, white, warm and cool white, amber, UV, lime) match by type across fixture models: a color change reaches every selected fixture that has that color, and a dimmer-only fixture gets the intensity.
• Other functions (Pan/Tilt, custom channels, color wheels, gobos) are shown only when every selected fixture uses the same profile and mode. Otherwise a note says some controls are hidden because the selection mixes fixture types.

When the selected fixtures differ on a control, its label shows Mixed (hover it to see the range, such as “12% to 80%”). The control shows the first selected fixture’s value, and moving it sets every fixture to the same value. Copy Trims are shown only with a single fixture selected.

Note

Selecting several fixtures is a Web UI feature. The touchscreen Fixture Control page controls one fixture at a time.

Multi-Function Support

Fixtures with multiple instances of the same function type (e.g., multiple color wheels or gobos) are fully supported. The Fixture Control page displays separate controls for each function instance.

Modifiers

When you adjust a fixture’s properties through Fixture Control, these are applied as modifiers - runtime adjustments that layer on top of the fixture’s base state. A badge indicator shows when a fixture has active modifiers.

Note

Modifiers are temporary adjustments. To keep a look, save it as a Preset - see below.

Saving as a Preset

Save as Preset in the header saves the checked fixtures as a new Preset, with one entry per fixture holding its current values and its running effect (with the effect dimmer). A link to the new preset appears in the header, so you can rename it or adjust it on the Presets page. Playing the preset later brings back the same look, and fixtures that share an effect run it in sync.

The Faders page has the same save behind its Build Preset button.

Fading to a Value

Slider changes normally apply live as you drag. Enable Fade in the header (with the duration select next to it, 0.5–30 s) and a slider gesture fades instead: release the slider and the DMX Core 100 fades the fixture smoothly to that value over the selected duration - the fade runs on the device itself, so it continues even if you close the browser. On a desktop browser, holding Shift while clicking a slider does the same thing without turning fade mode on.

Fading applies to the percentage sliders - intensity, extra color channels, and custom channels - and to the color wheel. While you drag the wheel with Fade on (or Shift held), a dashed ghost thumb marks the target; on release the color fades there. On the Square picker the outer ring fades hue and the square fades saturation and intensity; on the Disc picker the intensity slider fades along with the wheel. The numeric color fields, keyboard input and multi-function selectors always apply immediately. The fade mode toggle and duration are remembered per browser and shared with the Faders page, where the same gesture works on the vertical faders and masters (see Fading to a Level).

Effects

The Fixture Control page also gives access to the effects engine. Select one or more fixtures and pick an effect in the Effect card to apply an animated lighting effect - breathing, fire, pulsing, and more - to all of them at once; the Effect Dimmer below it sets how strongly the effect shows. Fixtures on the same effect run it in sync, including fixtures you add to an effect that is already running. When the selected fixtures run different effects, the Effect label shows Mixed.

Copy Trims

A fixture configured with more than one copy (see Fixture Setup) is treated as one unit - every copy gets the same color and intensity. In practice one or two of those units are often a little too bright or too dim compared to the rest: mounted closer to a wall, older LEDs, a slightly different batch. Rather than splitting the fixture apart just to fix that, you can give each copy its own intensity trim.

Select a multi-copy, dimmable fixture and open the Copy Trims card below the effect controls (it is collapsed by default - flip Show; the header always tells you how many copies are trimmed). Each copy gets a row with its DMX address, a slider (0–100 %), and a reset arrow:

• Drag a slider to preview the change on the physical fixture immediately; release to save it.
• S (Solo) lights only that copy - with every other copy of the fixture dark - so you can tell which physical unit is which before trimming it. Solo is a temporary preview only: it is never saved, and it ends when you toggle it off, hide the card, pick another fixture, or leave the page. Only one copy can be soloed at a time.
• Reset all returns every copy to 100 %.

Trims are stored on the fixture and apply whenever the fixture engine drives it - live control, presets, ambient presets, effects, and timelines that play presets. A trim only scales brightness (the intensity channel, or the color channels for fixtures without a dedicated intensity channel); it never changes color. Trims are kept when you clone the fixture, and when you split or combine copies each copy keeps its own value.

Note

Copy trims do not affect cue playback - recorded DMX bypasses the fixture engine. To tame recorded channels use Channel Rules instead; note that a channel rule applies to the output as a whole, so it also limits this fixture when a preset drives it. Solo needs the fixture to be lit: if the fixture’s intensity is at 0 % the soloed copy stays dark, and the card says so.

A copy trimmed all the way to 0 % stays dark whatever you do on this page - the fixture’s settings page warns about that so a forgotten trim doesn’t look like a dead unit. Editing trims requires the Edit Fixtures permission; anyone who can use Fixture Control can still Solo to identify copies.

Fade Speed

The fade speed for fixture control changes - how quickly fixtures transition when you adjust their values - is configurable, along with the priority the fixture engine outputs at (see Layers & Priority).
