Q Light Controller

Q Light Controller is a cross-platform application for controlling DMX or analog lighting systems like moving heads, dimmers, scanners etc. Our goal is to replace the hard-to-learn and somewhat limited commercial hardware/software lighting desks with FLOSS.

Known Issues

• QLC 3.0.7 Windows: sometimes after closing the application there's a crash. However, this crash happens at such a late stage that it doesn't have any effect on the application's stability while it's being run nor the workspace file. I have not yet found the exact cause of this, but workspace saving routines have already been completed when this error occurs so there shouldn't be any danger of losing your workspace data.

Tips & Tricks

• Installing D2XX drivers for Enttec DMX USB plugin in Windows (QLC 3.0.7 requires version 2.08.02).
• You need to install LibUSB-Win32 if you wish to use uDMX plugin on Windows.
• Enttec's USB widgets not working on linux ? Don't forget to remove legacy kernel module to let QLC do its job ! Here is the command line:

    sudo modprobe -r ftdi_sio
  

• To fix SELinux (Fedora) warning on Enttec USB DMX Plugin, you need to say (as root):

    chcon -t textrel_shlib_t '/usr/lib/qlc/output/libenttecdmxusbout.so'
