If you want to run straight up scenes, go with a plain DMX operator. I started out with four mighty scans and two dimmer packs controlled by one DMX Operator. Pre program lots of "looks" before the show and play them back. Real easy, it just takes some time programming the desired scenes.
At the venue where I run/program lights. We have five trackspots and six DMX dimmer packs all controlled by one DMX operator. Works perfectly. We have banks dedicated to different "moods".
For example:
Bank 1-3 are the "rock" looks. Lots of color changes, bright punch effects, etc.
Bank 4-6 are the "chill" looks. Deep dim colors, some slow gobo scrolling via the trackspots.
Bank 5 is the "emo" bank. Nothing but deep colors
Bank 6 is the "hard core" bank. Los of red. some strobing on the intelligent lights.
Bank 7 is the solo page where the intelligent lights key in on a performer on stage (ie scene 1 is on the drummer, scene 2 is on the left guiter, etc)
(hopefully you get the idea)
This setup works well when you have someone who knows NOTHING about lights running lights. I am not there all the time and sometimes we have volunteers run lights. You can't screw up with pre programmed scenes.
