I think I've made some headway. I can assign any midi channel number to any song and, using midi learn in Luminair, the lighting scene gets attached to the song. For example, midi preset 1 is on Channel 1 and triggers scene 1. I try to set the next song to midi preset 2, on Channel 2 with lighting scene 2 but it sets it to Channel 1, scene 1. But, when I set the next song, it sets it as Channel 2, scene 2. So, essentially, it takes two shots to 'stick' the midi preset. In short, song 1 is set to channel 1, scene 1. When I go to set song 2, it also sets as channel 1, scene 1. Then, if I go back to reset song 1, it will set to channel 2, scene 2. Confusing? A little, but at least there is a light at the end of this tunnel.
