Versions

Which version suits whom?

QLC+ comes in two lines, both maintained by the manufacturer: the new line 5 (latest 5.3.0 of 5 October 2026) and line 4 (latest 4.14.4 of 15 March 2026). Each is available for Windows, Mac and Linux. Until October 2026 the button on this page still pointed to QLC+ 4.12.2 from 2019.

Version Who it is for What sets it apart Requirements (minimum)
QLC+ 5.3.05 October 2026Recommended Everyone starting with QLC+ today — on Windows, Mac or Linux. The new line 5. According to the manufacturer’s announcement, 5.3.0 reaches the feature set of line 4 and goes beyond it with, among other things, a new stage wizard and a 3D position palette. Windows 10 or later; macOS 12 or later (Apple Silicon or Intel); Ubuntu/Debian, or as an AppImage for other Linux systems
QLC+ 4.14.415 March 2026 Anyone already working with QLC+ 4 who wants to keep its handling, guides and videos. The proven line 4, still maintained by the manufacturer. 4.14.4 saves the project automatically after 30 seconds without input. On Linux, line 5 can be installed alongside it. Windows 10 or later; macOS 12 or later (Apple Silicon or Intel); Ubuntu/Debian 24.04 or equivalent

The short answer

  • Windows 10 or 11: QLC+ 5.3.0 for Windows.
  • Mac with macOS 12 or later: QLC+ 5.3.0 for Apple Silicon or for Intel — which chip you have is in the box below.
  • Ubuntu or Debian: both 5.3.0 packages, program and data; other Linux systems take the AppImage.
  • You already work with QLC+ 4 and do not want to relearn: QLC+ 4.14.4 for your system.

Which file for my Mac?

The manufacturer builds a separate file for each kind of Mac: “Apple Silicon” for Macs with an M chip, “Intel” for older Macs with an Intel processor. Which chip your Mac has is shown in the Apple menu at the top left under “About This Mac”. Both files require macOS 12 or later.

More about QLC+

What QLC+ is

QLC+ is a free, open-source lighting control program for Windows, macOS and Linux; according to the manufacturer it also runs on the Raspberry Pi. It is developed by Massimo Callegari with a small core team and builds on QLC, the program by Heikki Junnila.

QLC+ handles any number of DMX universes. You operate it through the virtual console with mouse or touchscreen — or with an external desk via MIDI, DMX, Art-Net, E1.31 or OSC, then with real buttons and faders.

What you need for it

A computer, a DMX interface and a fixture definition for every fixture. QLC+ comes with a library of definitions from many makers; if a fixture is missing, you create it yourself in QLC+’s Fixture Editor.

Together with our interfaces

USB2DMX PRO and USB2DMX OPTO use an FTDI chip and work like an Enttec Open DMX. QLC+ drives such interfaces through its “DMX USB” plugin in “Open TX” mode. According to the QLC+ documentation, the plugin needs FTDI’s D2XX drivers on Windows and the libftdi library on Linux; on macOS it needs no driver. The documentation explicitly advises against the VCP drivers (virtual COM port), as they can interfere with QLC+.

The AIR2DMX PRO receives Art-Net over Wi-Fi. Art-Net is built into QLC+ on Windows, macOS and Linux, with nothing extra to install.
