QLC is a lighting controller for Linux. Started as a university project by Heikki Junnila, it has now evolved with an active development community. In 2009 it was released for Mac OS and Windows also.


  • Fixture-oriented interface.
  • Four DMX universes, 512 channels each
  • Fast changing and smoothly fading scenes and chasers
  • Easy creation of complex patterns for moving lights with EFX
  • Conjure/design your favourite lighting desk layout with the virtual consoleā„¢
  • Support for external fader devices such as the Behringer BCF-2000

DMX output is provided using:

  • the driver system OLA (via a plugin to QLC), allowing DMX output using various DMX over IP protocols and Enttec DMX USB Pro. (for Linux, Mac OS and Windows, not all drivers work on all platforms)
  • the Peperoni Rodin1 (well tested) interface, plugin named peperoni-output (Linux (requires kernel driver) and Windows)
  • the Enttec DMX USB Pro and Open DMX USB (Windows and Linux, Mac OS, tested rather well)
  • Anyma uDMX (Windows, Linux and probably Mac OS but not well tested)

At the moment there are most drivers for Linux and fewest for Windows. In v. 3.0 the plugin for OLA (formerly LLA) is not included/enabled per default.


QLC can be controlled by MIDI eg. from Behringer BCF-2000 and support for a Enttec wing may be added. Sound synchronization is not supported [1]


Inputs and outputs are provided through plugins to QLC, see the the details at QLC plugins.


Fixture definitions are used to map generic functions of a fixture like intensity, pan, tilt etc. to the specific DMX channels and values. You can create your own fixture definitions to suit your needs, but there are a number of ready-made definitions listed here! QLC has a graphical "fixture creator" program.


If you find a bug, you can report it here, or alternatively send an email to the qlc-devel mailing list.
