magic8192,
Last year was my first effort with computer controlled animation. I had no controllers until the first LE Coop late last year when I ordered 8 LEs which I received November 14th and then had to build. Fortunately everything came together.
Point being, I did all the planning and sequencing with no controllers just an Excel spreadsheet I made to track the projects, Vixen and its adjustable preview and astonishingly, the show pretty much looked just like the preview only much larger of course... Had to tweak some light intensities after the display was up but other than that everything worked exactly as imagined/planned and the scorched earth plan of shutting it off if it looked bad was averted.
So you're way ahead of where I was last year at this time. You'll do fine!
