Of course the smf with lyrics will scroll. You can set all this up in a performance mode, as I explained in another thread. I have medleys set up with a touch of (1) button after selecting "play all" from the jukebox. Just select the proper performance button (corresponding with the song) and you're ready to play arranger style, which will trigger the vocal harmonizer - very cool. (Still trying to figure out how to save the pads).
