I'm a real believer in using the VSA software from Brookshire Software. It only costs about $60 and supports just about every servo controller made.
VSA is very easy to learn. Changes to routines are easy to make, even on-site and at the last minute. You don't need to learn any programming language!
With VSA you can control lights, relays, dimmers, servos and more. There are plenty of add-on products also - like our (advertising here) Exorcist Haunt Controller and DMX interface.
