Troubleshooting
Symptom Cause/Action Page
Even though you’re using head-
phones and the sound is muted,
a thumping sound is heard when
you play the keyboard
This unit uses a hammer action keyboard in order to simulate an acoustic piano’s playing touch as realistically as possible. For this
reason, you’ll hear the hammers thump when you play the keyboard, just as you would when playing an acoustic piano. Since this
unit allows you to adjust its volume, you might notice the sound of the hammers in certain situations, but this does not indicate
a malfunction. If vibration transmitted to the oor or walls is a concern, you may be able to minimize the vibration by moving the
piano away from the wall, or by laying down a commercially available anti-vibration mat designed for use with pianos.

Power turns o on its own
When 240 minutes (4 hours) have elapsed since you last played or operated this unit, the power will turn o automatically. (This is
the factory setting.)
If you don’t need the power to turn o automatically, turn the “Auto O” setting o.
p. 15
Power does not turn on Is the AC adaptor connected correctly? p. 22
Pedal does not work, or is “stuck”
Is the pedal connected correctly?
Plug the cord rmly into the pedal connector.
p. 22
If you disconnect the pedal cord from this unit while the power is on, the pedal eect may remain “stuck” in the On condition. You
must switch o the unit’s power before connecting or disconnecting the pedal cord.

Could Twin Piano be turned on?
If Twin Piano is on, the right pedal will apply only to the right-hand section of the keyboard, and the left pedal will apply only to
the left-hand section of the keyboard.
p. 8
The volume level of the instru-
ment connected to Input jack is
too low
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.

No sound/
No sound when you play back
a song
Could the unit’s volume or the volume of the connected equipment be turned down? —
Could headphones be connected?
Could there be a plug inserted in a headphone jack?
The speakers will not produce sound if headphones or plug are connected to the headphone jacks.
p. 5
Has Local Control been set to “O”?
When Local Control is set to O, no sound is produced by playing back a song. Set Local Control to On.
p. 14
No sound from the leftmost notes
of the keyboard
Could the Visual Control mode be set to MIDI Visual Control or V-LINK?
If the Visual Control mode is set to MIDI Visual Control or V-LINK, the lowest 12 keys of the keyboard (A0–G#1) are used to control
images; they will not produce sound.
p. 13
No sound (when a MIDI device is
connected)
Are all devices powered on? —
Are the MIDI cables connected correctly? p. 14
Do the MIDI channels of this unit and the connected device match? p. 14
Not all the notes you play are
sounded
The maximum simultaneous polyphony is 128 voices. If you’re using the Dual tone (p. 18), if you’re playing along with a song, or if
you’re making extensive use of the damper pedal, the performance data may exceed the available polyphony, possibly causing
some of the notes you play to drop out.
—
Pitch of the keyboard or song is
incorrect
Could you have made Transpose settings? p. 13
Is the Master Tune setting appropriate? p. 13
The notes of a piano are tuned using a unique method (stretched tuning), which makes upper-range notes slightly higher in
pitch, and lower-range notes slightly lower in pitch. For this reason, you might perceive the pitch as being incorrect, but this is the
way an acoustic piano should sound.
—
Sounds are heard twice (doubled)
when the keyboard is played
Could you have selected a dual tone? p. 18
When this unit is connected to an external sequencer, set the Local Control to o. Alternatively, the sequencer could be set so its
Soft Thru feature is O.
p. 14
Reverberation remains even if you
defeat the Reverb eect
The unit’s piano sound faithfully simulates the depth and resonance of an acoustic piano, and this may give the impression of
reverberation even if you’ve defeated the Reverb eect.
—
The sound of the higher notes
suddenly changes from a certain
key
On an acoustic piano, the approximately one and a half octaves of notes at the upper end of the keyboard will continue sounding
regardless of the damper pedal. These notes also have a somewhat dierent tonal character. This unit faithfully simulate this
characteristic of acoustic pianos. On this unit, the range that is unaected by the damper pedal will change according to the
transpose setting.
—
High-pitched ringing is heard
If you hear this in headphones:
Piano sounds that have a brilliant and crisp character contain substantial high-frequency components that may sound as though
a metallic ringing has been added. This is because the characteristics of an actual piano are being faithfully reproduced, and
is not a malfunction. This ringing is more obtrusive if the reverb eect is applied heavily, so you may be able to minimize it by
decreasing the reverb.
—
If you don’t hear this in headphones:
It is likely that there is some other reason (such as resonances within the unit). Please contact your dealer or the nearest Roland
service center.
—
Sound wrong, or are buzzy
If you set the volume to the maximum setting, the sound may be distorted depending on how you perform. If this occurs, turn
down the volume.
—
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the unit to resonate. Fluorescent lights or glass doors may
also resonate sympathetically. In particular, this is more likely to occur for lower notes and higher volumes. You can take the
following measures to minimize resonances.
• Locate this unit 10–15 cm (4–6 inch) away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
