I'm looking to control lights (power outlets) via MIDI. The technology works like this: The MIDI out of a computer is sent to a processing unit which is then attached to a series of power outlets. Each power plug is assigned to a midi channel, and the "on"/"off" signals of the MIDI out turn the corresponding power outlet on or off. I'm looking for the MIDI processing unit / power plug unit (I've seen them combined and seperated into two. I'd like to have at least a dozen outlets...I believe they can be chained.
I know it can be done because I've seen it in action, I just can't remember the name of the gear / technology. A link to the gear or tutorial would be great! Thanks!
