QLC (Q Light Controller) has direct support for uDMX. Direct support means that DMX4Linux is not necessary. On the other hand you need LibUSB for Linux, to compile the plugin.

QLC has to be started as root in some versions [ sudo qlc ] so that the uDMX plugin will work. Try this out (only) if you experience problems with uDMX plugin.

You only get the source for the version 2.6.x. You have to do manual changes in the file configure.in of the qlc-project.

I hope everything you need is explained in the documentation of the sourcecode.

In the newest version QLC runs on Windows as well
