Quoted from delt31:
what exactly is needed to do this? Parts wise? Mine current has Eli
Well, currently it requires a Total Lightshow kit WITH a second main board. I could ship it like that within a few weeks, but I'm going to try reduce the parts by sending the signals for the GI via the sound caller, but that will take a while.
If you were happy to have the ramps on white between effects, you could piggyback the GI of the ramp signals and do it with a current Tron TLS kit with only the bulbs needed as extra. This is not the long term solution though, as you want the ramp control independent of the GI.
