The software that you program the lights to go on, off, flicker, fade down, fade up with looks like a spreadsheet. The rows on the left side are your electrical channels or circuits. The columns are your timing blocks to turn the lights on and off.

The timing marks are adjustable from .1 seconds to ??
You decide when you want the lights to blink, on , off, ect. with the music by highlighting a particular cell on what ever channel you want. The new software has a visual sound wave to help see the music beats and sounds. Which makes it a lot easier to see if your cells line up with the music beats
As the music plays the cursor moves from left to right. As it crosses over the colored cells it tells that channel what electrically to do.
All of this info is then transferred to the controllers that are outside where your lights and displays are at thru a cat 5 computer cable. The controller then deciphers all of this and then turns the electricity to your lights on, off, blink, fade, or whatever you programmed it to do.
The picture below represents the style of controller I use. 1 power cord in and 16 controlled power cords out.
