Selecting & Playing Voices

The instrument has a wide variety of Voices, or instrument 
sounds, for your enjoyment, including Piano and Organ.

1

Pressing the same Voice button alternates the on/off 
status of the lamp, changing between the Voices 
whose names are printed above and below the line.

By using the instrument’s Sound Boost function when 
playing along with other instruments, you can raise 
the volume and enhance the presence of your perfor-
mance without sacrificing any expressiveness. This 
function is particularly useful when you want not only 
notes played very loud, but also those played softly, to 
be clearly audible.
While holding down [METRONOME/RHYTHM] 
and [PIANIST STYLE] simultaneously, press the C4 
key to turn on, or press the C

#4 key to turn off.

You can play Voices simultaneously across the entire

side button is designated as Voice 1, while the Voice 
of the right side button is designated as Voice 2.

Press the desired Voice button once or twice 
(depending on the desired Voice), then while hold-
ing down that button, press the other Voice button 
once or twice. When the lamp is off, the Voice 
printed above the line is selected; when the lamp is

buttons are released, Dual is engaged. The lamp 
indicates the status of the Voice 1 selection.

Selecting a Voice

GRAND PIANO

Sampled from a concert grand piano. It uses 
different samples depending on the playing 
strength and produces smoother tonal 
changes. Suitable not only for classical com-
positions but also for any style music.

BRIGHT GRAND

Bright piano sound. Clear tone helps the 
sound to “cut through” when playing in an 
ensemble.

MELLOW 
GRAND

Warm and soft piano sound. Good for play-
ing ballads.

DX E.PIANO

An electronic piano sound created by FM 
synthesis. Good for standard popular 
music.

STAGE 
E.PIANO

Vintage electric piano sound of hammer-
struck metallic “tines.” Soft tone when 
played lightly, and an aggressive tone 
when played hard.

VINTAGE 
E.PIANO

Another vintage electric piano sound dif-
ferent from STAGE E.PIANO often heard 
in rock and popular music.

JAZZ ORGAN

A “tonewheel” type electric organ. Often 
heard in jazz and rock music. When the 
separately sold Pedal Unit (LP-5A/LP-
5AWH) is connected, the rotary speed of 
the “ROTARY SP” effect can be switched 
by using the left pedal.

PIPE ORGAN

A typical pipe organ sound (8 feet + 4 feet 
+ 2 feet). Good for sacred music from the 
Baroque period.

ROCK ORGAN

Bright and edgy electric organ sound. Good 
for rock music. When the separately sold 
Pedal Unit (LP-5A/LP-5AWH) is connected, 
the rotary speed of the “ROTARY SP” effect 
can be switched by using the left pedal.

VIBRAPHONE

Played with relatively soft mallets. The tone 
becomes more metallic the harder you play.

STRINGS

Stereo-sampled, large-scale strings 
ensemble with realistic reverb. Try combin-
ing this Voice with piano in the Dual mode.

HARPSI-
CHORD

The definitive instrument for baroque 
music. Authentic harpsichord sound, with 
plucked strings, no touch response, and 
characteristic key-release sound.

WOOD BASS

An upright bass played fingerstyle. Ideal 
for jazz and Latin music.

E. BASS

For a wide range of music styles, jazz, 
rock, popular, and more.
