Our display is controlled by a computer which plays the music and sends commands over a network to light controllers. We currently have 19 controllers that each have 16 light circuits for a total of 304 individually controlled circuits. The items in our display are a combination of home made and commercially available products.
The heart of the system is software and controllers from Light-O-Rama (LOR). This solution allows you to control Christmas lights (either incandescent or LED), spot lights, and other display items. The actions of the various items can be synchronized to music. The LOR software suite allows creation/editing of animation or musical sequences. It also includes utilities to create and schedule shows, run the show, and test the hardware/lights.
Light actions that can be done on each circuit are: On, Off, Fade up, Fade down, Twinkle, Shimmer, and more. Different circuits can perform different actions simultaneously.
