Design Tools

Lighting

  • Control unlimited Art-Net DMX universes.
  • Create unlimited light instruments (like channels, but can be named anything, not just numbers).
  • Create unlimited light groups to collect related instruments together, like "all", "stage right", "LEDs", "floor", or "floor front left".
  • Use both conventional dimmers and more complex lights with multiple parameters (includes support for percentage-based parameters, as well as both 8-bit and 16-bit direct DMX parameters.)
  • QLab-style levels fading: it's simple to build looks and effects that you can layer and reuse. A Light cue changes only the levels you set in the cue, and leaves the rest unchanged.
  • Build sophisticated lighting designs by chaining Light cues together to build complex cue sequences out of simpler parts, then trigger the sequence with a single “GO” like a chain of dominoes.
  • As with all cues in QLab, Light cues can be copied, pasted, reordered, paused, resumed, and stopped at any time
  • All QLab fade curves are available for Light cues; including linear, s-curve, or totally custom shape fades.
  • See and manipulate the current levels of all your lights using the Light Dashboard.
  • If you need to sneak in live edits from the Dashboard, you can optionally tell QLab to apply the new values "over time" so they'll fade in smoothly.
  • Open the Audition Window to view the effects of light cues “blind” in the dashboard. Close the Audition Window, and the dashboard will instantly revert back to show the live state of your lights.
  • Adjust your lights in the dashboard, then:
    • Create a new cue with just the changes,
    • Create a new cue with all instruments,
    • Update the last-run light cue with the changes, or
    • Trace back the edits to each cue that most recently modified each instrument.
  • Map your favorite MIDI controller to light commands, for editing either the light dashboard or individual cues.
  • For motorized MIDI hardware, QLab supports MIDI “feedback” from the light dashboard and individual light cues. (Aka “flying faders”.)
  • Use QLab’s powerful light command language, with autocompletion, instrument or group parameter addressing, ranges, ad-hoc groups, and command history, to efficiently edit both the light dashboard and individual light cues.
  • View light cues as sliders, tiles, or raw command text at any time.
  • View the Light Dashboard as sliders or tiles.
  • Edit lights via keyboard entry (on the command line) or with the mouse (via clicking and dragging.)
  • Easily delete individual light commands from any cue, and of course undo any edits.
  • In slider view, expand group commands into all the individual instruments currently in the group.
  • In slider view, indicators show the current live value of each light in a cue.
  • In slider view, select multiple commands to temporarily “gang” them, so you can adjust them up or down together.
  • Quickly see when a group of instruments is set to all the same level or a mix of different levels.
  • Batch-edit multiple light cues by selecting them and then simply editing any light command they all share. (Or adding a new command to all of them at once.)
  • Use AppleScript, either externally or via Script cues, for advanced programming techniques like algorithmically generating a series of Light cues.
  • Control both the Light Dashboard and individual Light cues via OSC messages.
