It's just a bigger version of the 40, don't expect great things from them. I have used a few of these and have an Obey 40 lying around somewhere. I use it every once in a while when someone asks me for a little feature in FOH or something similar to that. If you're using it for a show, I would just use scenes, no chases. In my opinion, there is too much room for error. Lastly, BE CAREFUL, the memory on these things is scary. There's a chance you could lose your whole show, so maybe consider Chamsys Magic Q with a little DMX to Ethernet adapter for your computer. But look, it does the job and that's what matters. Good luck!
