When you think about it, if the MFD were expanded to include all the save features of a registration, then there would be no need for registrations. The same would be true if the MFD were eliminated and the registrations were automatically alphabetized regardless of whether the registrations were individualized or done as a full bank. In their favor, Yamaha provides you with more options in that you can select from three, different methods to store and select your songs. It's up to the player to determine which is more suitable for their needs. It can be as simplistic as the MFD, or as complex as registrations - take your pick.
