RHYTHM SELECTOR 10 kinds of rhythm buttons for Jazz and Latin, and the 10 buttons for Latin rhythms employ an automatic cancel system. The Latin rhythms do not come out unless LATIN is ON.

Only when the button for Mambo was pressed before, Mambo comes out by pressing LATIN, and Waltz is automatically canceled. Reversely, when the button for Mambo is ON, pressing of Waltz button will make cancellation of Mambo with automatical change of LATIN. Notice the speedy tempo of Slow Rock, Ballade, Jazz-Waltz, Waltz, 6/8 March and Bolero.
