Setting Up Connecting a Pedal Unit (PEDAL UNIT jack) This jack is for connecting an optional LP-7A pedal unit. When connecting the pedal unit, make sure to also assemble the unit on the supplied keyboard stand. NOTE • Make sure that power is OFF when connecting or disconnect- ing the pedal. Setting Up Keyboard LP-7A (optional) Stand 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 Footswitch 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 subsequently 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. When you press the damper pedal here, the notes you play before you release the pedal have a longer sustain. When you press the sostenuto pedal here while holding the note, the note will sustain as long as you hold the pedal. 14 Owner's Manual
