The controller connects up to four drapes and is sold separately. It can run independently or by 12 or 24 DMX channels, has built-in programs, or can completely control up to eight zones (16 LEDs per zone) of each drape. The controller features an LCD display, RGB color mixing control (with or without DMX control), a proprietary serial link (master/slave), and configurable color sets. Additionally, it offers configurable LED sparking direction and speed, group sparking cross fade time, and minimum and maximum luminosity. Users can configure auto programs or recall custom programs via DMX. .
