in the mid 2010s, i had plans to cook up something with the serial family of opcodes to do light cues along with sound cues for an off brand cafetorium lighting system but i couldn't get any rs-485 signals to jive with the dimmer system.
in the late 1990s i ran some midi compositions through an etc console after discovering it had a midi implementation. it was twinkly experiment. but i never really got around to any light designs for it.
