Connecting A Pedal Unit (Pedal Unit Jack) - Yamaha Portable Grand DGX-630 Owner's Manual

Setting Up
Pedal Unit Functions
The optional pedal unit has three foot pedals that produce a range of
expressive effects similar to those produced by the pedals on an acoustic
piano. The pedal unit does not affect the split voice when the keyboard is
in split mode.
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 sustain
longer. Releasing the pedal immediately stops (damps) any sustained
notes.
A "half-pedal" effect lets you use the damper pedal to create partial
sustain effects, depending on how far down you press the pedal.
* When using both the foot switch and pedal unit, the last effect applied takes
priority.
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 sustain as long as you
hold the pedal (as if the damper pedal had been pressed) but all subse-
quently played notes will not be sustained. This makes it possible to
sustain a chord, for example, while other notes are played "staccato."
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 that are already playing when it is pressed.
