Polyphony
The term polyphony refers to the maximum number of notes you can play at the same time. This keyboard has 12-note polyphony, which includes the notes you play as well as the rhythms and auto-accompaniment patterns that are played by the keyboard. This means that when a rhythm or autoaccompaniment pattern is being played by the keyboard, the number of notes (polyphony) available for keyboard play is reduced. Also note that some of the tones offer only 6-note polyphony. � When rhythm or auto accompaniment is playing, the number of sounds simultaneously played is reduced. � Though you can sound up to 12 notes at one time, only the last four keyboard keys pressed light up.

� NOTE
� If you leave the transpose screen on the display for about five seconds without doing anything, the screen is automatically cleared. � You cannot change the transpose setting while the keyboard is in the Song Bank Mode. � In step 2 of the above operation, you could also use the number buttons 0 to 5 to specify C through F. � Pressing both of the TEMPO buttons ( / ) at the same time returns the transpose setting to C(0). � The transpose setting is automatically set to C(0) whenever you turn keyboard power on. � The transpose setting is automatically set to C(0) whenever you press the SONG BANK button. � The pitch of a transposed note depends on the tone you are using. If the transpose operation causes a note to exceed the range of the tone you are using, the same note in the highest octave of the tone�s range is substituted. � The transpose operation does not affect tone number 99 (PERCUSSION) or auto-accompaniment rhythms. � Transposing tones 75 through 79 and 90 through 96 changes the range of keys to which each of the tones is assigned. � The transpose setting is automatically set to C(0) whenever you press the DEMO button.
