To program the lights to flash, fade, twinkle, change color, etc. The Light-O-Rama sequencing software allows you to load the music file into a time grid. There is a row for each channel. In each row you program the lights as you wish. The software also provides a Visualization tool which allows you to get an idea of what the display will look like without actually having to run out into the yard to see how it looks. This allows us to program any time that we want, not just when the lights are up. See the pictures below of the sequencing and visualization tools.
During the show, the computer sends commands to the control boxes for each of the different outlets as often as 100 times per second. At the same time, the computer is sending the music to a low power FM transmitter so that visitors can listen to the music from the comfort of their car. We also use several outdoor speakers so that the music can be heard in front of the house.
