YDP-121
The YDP-121 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.

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."
NOTE

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 the song start/stop operation
via the "Left Pedal Mode" described on page 26.
