Midi is not needed here. The solution to my problem would be some so-called DMX
controller, which act as an interface between the PC and (DMX?) dimmers.

The idea would be to modify my application (Jackbeat) to control light in
addition to sound, using dmx4linux (see: http://llg.cubic.org/dmx4linux) and a
supported DMX controller.

Now, I really need to learn some more about what happen on the output of this
DMX controller thing... I'm very new to this lighting stuff.

Here's the list of supported devices supported by dmx4linux:

I just checked this 55 EUR Enttec USB controller :

This firm seems to officially support Linux. Looks great...
