The mini Mega is on Sweetwater's site with all purple lights. You apparently can change the colors of the lights to other colors. No mention of midi in on SW's page though. Hope it isn't something that is being left off. I see no builtin system of saving patches or anything. So, maybe just FX loop in out, Compressor in/out and things like that via midi.
Do you have a link to the Sweetwater listing? I could not find it.
