Pedal Functions
About DSP
DSP makes it possible to digitally produce complex
acoustic effects. The DSP is assigned to each tone
whenever you turn on Digital Piano power.
 Damper Pedal
Pressing the damper pedal while playing will cause the
notes you play to reverberate for a long time. Halfpedal operation (pressing the pedal part way) is also
supported.
• When one of the GRAND PIANO tones or the
MODERN piano tone is selected, using the damper
pedal adds damper resonance that is similar to that
produced on an acoustic grand piano.
 Sostenuto Pedal
Only the notes of the keys that are depressed when this
pedal is pressed are sustained until the pedal is
released.
 Soft Pedal
Pressing this pedal while playing suppresses notes
played on the keyboard after the pedal was pressed,
and makes them sound softer.
NOTE
• If pressing the pedal does not produce the desired
effect, it could mean that the pedal cord is not
connected properly. Refer to step 1 under “To
connect the cable” (page EN-53).
EN-10
Playing with Different Tones
Disabling Damper Noise Output
Damper noise is a slight metallic ringing sound that is
generated as the damper of an acoustic piano separates
from the wires pedal when the damper pedal is

the procedure below to disable its output. Damper
noise can be applied to the four piano tones (three
GRAND PIANO tones and MODERN).

Port Handling Precautions
IMPORTANT!
• Be sure to observe the precautions provided in the
documentation that comes with the USB flash drive.
• Avoid using a USB flash drive under the following
conditions. Such conditions can corrupt data stored
on the USB flash drive.
– Areas subjected to high temperature, high
humidity, or corrosive gas
– Areas subjected to strong electrostatic charge and
digital noise
• Never remove the USB flash drive while data is
being written to or loaded from it. Doing so can
corrupt the data on the USB flash drive and damage
the USB flash drive port.
• Never insert anything besides a USB flash drive into
the USB flash drive port. Doing so creates the risk of
malfunction.
• A USB flash drive can become warm after very long
use. This is normal and does not indicate
malfunction.
• Static electricity conducted to the USB flash drive
port from your hand or from a USB flash drive can
cause malfunction of the Digital Piano. If this
happens, turn the Digital Piano off and then back on
again.

Connecting a USB Flash Drive
to and Detaching It from the
Digital Piano
IMPORTANT!
• Never plug any other device besides a USB flash
drive into the USB flash drive port.
• When you plug in a USB flash drive, the Digital
Piano initially needs to “mount” the USB flash drive
and prepare for data exchange. Note that Digital
Piano operations are momentarily disabled while a
USB flash drive mounting sequence is being
performed. The Digital Piano’s L/R lamps flash while
the mounting process is in progress. It may take up
to 10 or 20 seconds or even longer for a USB flash
drive to be mounted. Do not attempt to perform any
operation on the Digital Piano while a mounting
sequence is in progress (while L/R lamps are
flashing). A USB flash drive needs to be mounted
each time it is connected to the Digital Piano.

is a “quick format”. If you want to completely delete
all of the data in USB flash drive, format it on your
computer or some other device.
