Soft Sostenuto Damper
Important: Before using the pedals, make
sure that the pedal cable is correctly in-
serted in the appropriate PEDAL socket at
the back of the instrument’s module.
5. Play using the pedals
TheRPT114 is fitted with three pedals:Soft, Sostenutoand Damper.
SOFT: The Soft pedal (left) affects the timbre of the sound such that it
plays softer, allowing you to continue using the same playing style at
a lower volume.
SOSTENUTO:theSostenuto pedal(centre) sustainsthenotes ofthe keys
currently pressed. All new notes played after having depressed the
pedal will not be affected.
• You can hold Organ, Choir and Strings sounds for as long as the
Sostenuto pedal is depressed.
DAMPER: The Damper pedal applies the Sustain effect to all notes
played. Ifyou release anote after depressingtheDamper, thenotewill
proceedtowardsitsnaturaldecayaccordingtothetypeofsoundplayed.
The Damper is particularly effective with Piano type sounds. In the
case of Organ and Strings sounds, the notes will be held for as long as
the Damper is depressed.
Note:forallpianotypesounds,thenotes of the uppermost keys(fromE6
to C8) are automatically sustained, such as in an acoustic piano.
