John, Yamaha's Music Finder and Registrations are two, entirely different things. The Music Finder Directory (MFD) is essentially a miniaturized version of a registration, in that it can only save the song title, tempo, style, intro and variation.

A registration bank, which consists of 8 separate registrations can save nearly every feature on the keyboard in a single location. Therefore, when I registration is stored it can selectively save: song title, style, tempo, variation, right hand voice(s), mic setting, pedal setting, intro, lyrics, midi file, and more on the newer keyboards.

Hope this helps,
