Ah I see what you’re saying, You CANNOT use 8 songs per bank and split them in a playlist.  It works with 1 song per bank but in that bank you can add any variation, voice, multipads, pedal assignments.   Why wouldn’t you just assign 1 song per bank?  
Hi Stephen,
that’s what I’m doing. Work’s really well for me, there again I don’t need 1000’s of songs.
 Works really well with the Registration Sequence function.  Have to use that when I use my piano as a controller for sx.
