The Pedals

The Clavinova has three foot pedals that produce a range of expressive
effects similar to those produced by the pedals on an acoustic piano.

Damper (Right) Pedal

The damper pedal functions in the same way as a damper pedal on
an acoustic piano. When the damper pedal is pressed notes played have
a long sustain. Releasing the pedal immediately stops (damps) any
sustained notes.
When the GRAND PIANO 1 voice is selected, pressing the damper
pedal activates the instrument's special "Sustain Samples" to accurately
recreate the unique resonance of an acoustic grand piano's soundboard
and strings.
• The depth of the effect produced by the "Sustain Samples" can be
adjusted via the "Pedal Functions" (page 32) in the function mode.
• If the damper pedal doesn't work, or notes are sustained even when the
pedal is not pressed, make sure that the pedal cord is properly plugged
into the main unit (page 50).

Sostenuto (Center) Pedal

If you play a note or chord on the keyboard and press the sostenuto
pedal while the note(s) are held, those notes will be sustained as long as
the pedal is held (as if the damper pedal had been pressed) but all
subsequently played notes will not be sustained. This makes it possible
to sustain a chord, for example, while other notes are played "staccato."
• Organ, string and choir voices will continue to sound for as long as the
sostenuto pedal is depressed.

Soft (Left) Pedal

...............................................................................................
The soft pedal reduces the volume and slightly changes the timbre of
notes played while the pedal is pressed. The soft pedal will not affect
notes which are already playing when it is pressed.
The left pedal can also be assigned to song start/stop operation via
the "Left Pedal Mode" described on page 32.
