Hi jimbell52,
alternatively (instead of saving the original Style as a User Style), you can simply save all changes/edits to Registrations. (Be sure that at least the checkboxes Style, Voice, Harmony/Arpeggio and Tempo are ticked when memorizing the current settings to a Registration button.)
Finally you have to save the current Registration Bank as a file in the User drive or (better) on a USB stick of course. (I is best to use the Song name as file name of each Registration Bank file.)
Best regards,
Chris
