Yes, I agree with what your saying.
The thing about this Compu live software is, it does not have a master dimmer like other major consoles.
Using a MIDI console or a simple DMX console, like the Elation SD6C, you can use these other consoles external faders, that you can assing to the dimmers of your lights, then you will have dimming control of you softare as you would with the consoles your used to.
However this software works a bit differenty than other consoles, so it does have a few things to learn to get around.
I wouldn't recommend doing a show with it until you get a good understanding of the software.
