Abstract

Provided is a system for controlling lighting effects. The system comprises a controller and one or more wireless dimmer devices with incorporated digital effects engine. The controller transmits wirelessly and effects parameters to the wireless dimmer devices. The dimmer devices receive the effects parameters, generate output effects parameters using the digital effects engine, and provide the output effects parameters to either dimmer output channels or DMX output channels. The digital effect engine comprises a low frequency oscillator and several random number generators. The random number generators may be used to modulate frequency of the low frequency oscillator and modulate a level of each dimmer output channel. The random number generators are configured to generate independent strings of pseudo-random numbers.
