Luminair has a Midi Learn feature. When I press midi learn and then play the Setlist Maker song with the non-defined midi preset, I suspect it is only responding to the midi message it received, regardless of whether it is defined or not. The Luminair manual doesn't offer much information and, while their email responses have been quick, they, too, have not offered much information. I am aware that it is probably me that can't understand the information but, as long as it works, I am happy, even if I have no idea of what I'm doing!
