We use Light-O-Rama to program our lights to music. Our lights are all linked to a 16-channel controller that can dim, shimmer, and turn on and off the lights. I do all the sequencing by myself on the computer, which can take between 3-8 hours to do a single song. Once a sequence is complete, I transfer the files to an SD Card. The SD Card has information on what to play so I don't need a computer to run the show. I plan on adding another controller box next year, which will bring out total to 32 channels.
