The meat of the Light-O-Rama Software Suite is the Sequence Editor, which lets you create light sequences that are synchronized with music. A sequence is a file that stores the information needed to synchronize lights with one selection of music. The music itself is stored in a separate audio file in the MP3 format.

You can also use the Sequence Editor to play a sequence. When it plays a sequence, the MP3 file is loaded and played through your computer's speakers or other audio output. In addition, the Sequence Editor sends instructions to the ShowTime PC controller to activate the lights in sequence with the music.

In Light-O-Rama, a sequence is usually associated with an individual song. Two or more sequences can be combined to create a show, which lets you cycle through a set of songs so that your audience doesn't have to watch just one song over and over again. You can also set up a schedule, which automatically starts and stops shows on particular times and days. Thus, by setting up sequences, shows, and a schedule, you can completely automate every aspect of your light show.

You can purchase preprogrammed sequences from Light-O-Rama's website for about $30 per song. Programming even a simple sequence for a single song can easily take 10 hours or more, and programming complicated sequences can quickly become a full-time job. So even at $30 per song, purchasing preprogrammed sequences can be worthwhile.
