THE CONTROLS ANDCONNECTORS

q [POWER] Switch

Press the [POWER] switch once to turn the power
ON, a second time to turn the power OFF. When the
power is initially turned ON, the PIANO 1 voice se-
lector LED will light.

w [MASTER VOLUME] Control

The [MASTER VOLUME] control adjusts the vol-
ume (level) of sound produced by the PDP-300. The
[MASTER VOLUME] control also adjusts headphone
volume when a pair of headphones is plugged into the
HEADPHONE jack i.

e [REVERB] Button

The [REVERB] button selects a number of digital
effects that you can use for extra depth and expres-
sive power.
To select an effect press the [REVERB] button a
few times until the indicator corresponding to the de-
sired effect lights (the indicators light in sequence
each time the [REVERB] button is pressed). No ef-
fect is produced when all indicators are off.
PEDAL
When the PEDAL indicator is lit, a subtle but warm
reverb effect is added to the sound whenever the
damper pedal is pressed.
ROOM
This setting add a continuous reverb effect to the
sound that is similar to the type of acoustic rever-
beration you would hear in a medium-size room.
HALL
For a really spacious reverb sound, use the HALL
setting. This effect simulates the natural reverbera-
tion of a large concert hall.
Note: When the [POWER] switch is initially turned ON all
reverb effects are turned OFF.

r [MIDI/TRANSPOSE] Button

The [MIDI/TRANSPOSE] button allows access to
the PDP-300’s TRANSPOSE function (to shift the
pitch of the entire keyboard up or down) and MIDI
functions. For details refer to the “TRANSPOSI-
TION” and “MIDI FUNCTIONS” sections on pages 7
and 8, respectively.

t Voice Selectors

The PDP-300 has six voice selectors. Simply press
any of the voice selectors to select the corresponding
voice. The LED indicator above the voice selector
will light to indicate which voice is currently se-
lected.
The PDP-300 also has a DUAL mode in which two
voices can be played simultaneously across the full
range of the keyboard — see page 7 for details.
Note: The PIANO 1 voice is automatically selected
whenever the [POWER] switch is initially turned ON.

y Soft/Sostenuto Pedal

This pedal has two distinct modes — “soft” and
“sostenuto” — which can be selected as required.
The Soft Mode
This is the normal mode for the Soft/Sostenuto
pedal, and is automatically selected when the power
is initially turned ON.
In this mode, pressing the pedal reduces the vol-
ume and slightly changes the timbre of notes
played.
The Sostenuto Mode
From the normal Soft mode, the Sostenuto mode
can be selected by holding down the [MIDI/
TRANSPOSE] button r and pressing the Soft/
Sostenuto pedal once.
In the sostenuto mode, if you play a note or
chord on the keyboard and press the 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.”
From the Sostenuto mode it is possible to return
to the Soft pedal mode by holding down the [MIDI/
TRANSPOSE] button and pressing the Soft/Sos-
tenuto pedal.
