Thanks Marcus and Yaneck for your answers.
Marcus solution works but take a lot of time to do.
Yaneck, that's not exactly what i am searching for.
To be more precise, i have several fixtures in my executor lighting a stage.
I would like to see what is doing only one of this fixture.
The goal would be to run the executor and then the "command solo" or the "touch solo" (i am searching for) + the fixture i want to see, make the varation i want and record this in the executor.
With several fixtures, it would be to select them, and to see one by one with the next and previous touch, like the highlight but with the dimmer value recorded for this fixture and the over fixtures dimmers of the executor at zero.
I don't know if it is possible, but i would find it very useful.
And sorry for my little poor english
Is there a way to active only one fixture from on executor, like a "solo touch" on a sound mixer?
Thank you for your answer
