The ScottEffx flickerSong App controls one or more flickerSongs to play music light shows, dim the LED string lights, or schedule autonomous timed events on each of the connected 8-output flickerSongs. The light shows are created on a MacIntosh using a companion App, simulated, bounced, and published as .mp3 music files containing all the light show meta-data used by this App and the Mac App. Both Apps are free, and using graphics freeware and your favorite music DAW you can create and publish music light shows for purchase and use by the ScottEffx flickerSong community.
