The Pedals

The YDP-88 has two foot pedals that produce a range of expressive effects similar to
those produced by the pedals on an acoustic piano.

Transposition

The YDP-88's TRANSPOSE function makes it possible to shift the pitch of the entire key-
board up or down in semitone intervals up to a maximum of six semitones. "Transposing" the
pitch of the YDP-88 keyboard facilitates playing in difficult key signatures, and you can easily
match the pitch of the keyboard to the range of a singer or other instrumentalist.
The [TRANSPOSE] button and keys F#2 through F#3 on the keyboard are used for transposition.

When the power is turned on the left pedal is set for soft pedal operation.
Pressing the soft pedal reduces the volume and slightly changes the timbre
of notes played.
The left pedal can be switched to sostenuto operation by pressing the
pedal while holding the [TRANSPOSE] button. 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 sus-
tained. This makes it possible to sustain a chord, for example, while other
notes are played "staccato." You can switch back to soft pedal operation at
any time simply by pressing the pedal while holding the [TRANSPOSE]
button again.
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.

* Pressing the C3 key produces normal keyboard pitch. Pressing the key to
the left of C3 (B2) transposes the pitch of the keyboard down a semitone,
the next key to the left (Bb2) transposes down a whole tone (two semi-
tones), etc., down to the F#2 key which transposes down 6 semitones.
Upward transposition is accomplished in the same way using the keys to
the right of C3, up to F#3 which transposes up 6 semitones.
