Q Light Controller+

QLC+ is an open‑source lighting console that lets users control DMX and analogue lighting fixtures. It provides a graphical interface for adding and patching fixtures, then building scenes, chasers, effects, and RGB matrices that can be triggered manually or via audio input. The software also includes a virtual console that can be customized for specific workflows, and it supports scripting to extend functionality with commands such as blackouts or system calls.

The program runs on macOS, Windows, and Linux, and it can communicate with a variety of hardware interfaces and protocols, including Art‑Net, sACN, OSC, and MIDI, through built‑in plugins. Users can synchronize lighting cues with audio or video playback, and future updates plan to add BPM detection for rhythm‑based triggering.

Designed for professionals, DJs, and hobbyists, QLC+ aims to replace expensive proprietary consoles with a free, community‑maintained solution that remains stable and feature‑rich while being accessible to users of all experience levels.
