peter Thanks, Peter. Maybe I'm misunderstanding the network feature. Even though we're on the same song, my wife's lyrics/notes are totally different than mine (I sing and play guitar, she plays key bass). One of us may use lyrics and the other PDF, etc. Also, from personal experience I would never trust Bluetooth or Wi-fi for live gigging. I'm using hard-wired MIDI and PC commands at present. Changing Live Sets on her MODX+ took me 2 days to figure out. I'll post separately about that experience.
One thing I don't know and it isn't explained as far as I could tell, is the Song Select command - how that would work, when you would use it etc.
