Style-Related Settings Setting the Split Point Set the point on the keyboard that separates the right and left-hand sections (Split Point). When Auto Accompaniment is off, keys played in the left-hand section are used for playing the Left Voice. When Auto Accompaniment is on, the left-hand section becomes the Chord section (Auto Accompaniment range) and the chords played in the Chord section produce an appropriate Auto Accompaniment playback, and add the Harmony effect to the notes played in the right-hand section.
