Symptom
Cause/Action

Even though you’re using
headphones and the sound
is muted, a thumping sound
is heard when you play the
keyboard
The 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 floor 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 off on its own
When 30 minutes have elapsed since you last played or operated this unit, the power will turn off automatically. (This is the
factory setting).
If you don’t need the power to turn off automatically, turn the “Auto Off” setting “OFF.”
Power does not turn on
Is the AC adaptor connected correctly?
p. 62
Could you have turned the power on again immediately after turning the power off?
Allow an interval of at least five seconds before turning the power on again.
–
Screen display is irregular when
power is turned on/off
Since the unit uses a liquid-crystal display, you may find that it is unable to display letters or other things in environments where
temperatures go below 0 degrees Celsius (32 degrees Fahrenheit).
–
Pedal does not work, or is “stuck”
Is the pedal connected correctly?
Plug the cable firmly into the pedal connector.
p. 62
If you disconnect the pedal cord from the unit while the power is on, the pedal effect may remain “stuck” in the On condition.
You must power-off the unit before connecting or disconnecting the pedal cord.
p. 62
Could you have changed how the pedal effect is applied?
If the damper pedal part is set to “R,” the pedal will apply only to the right tone; if it is set to “L,” the pedal will apply only to the left
tone.
Could Twin Piano be turned on?
If Twin Piano is on, the right pedal will affect only the right-hand keyboard zone and the left pedal will affect only the left-hand
keyboard zone.
Could you have changed the function of the pedal?
If you’ve reassigned the function of the center pedal, this pedal will not operate as the sostenuto pedal.
Unable to read from/write to USB
flash drive
Are you using (optional) Roland USB flash drive?
Reliable performance cannot be guaranteed if you use non-Roland USB flash drive products.
–
If you are unable to read or write USB flash drive successfully, change the USB memory mode.
“Buzz” is heard from external
devices
Are the external devices connected to more than one AC power outlet?
If you connect external devices, be sure to connect them to the same AC outlet.
–
The volume level of the
instrument connected to Input
jacks is too low .
HP505 only
Could the Input volume be set to “0”?
Raise the volume of the connected device.
–
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
–
Connected MIDI device does not
operate correctly
If turn off the unit, or the power is disrupted due to a power failure while you’re connected to a MIDI device, the settings of
that MIDI device may be altered. If this occurs, power-off the unit and your MIDI device. Then power-on the unit first, and next
power-on your MIDI device.

Has Local Control been set to “OFF”?
When Local Control is set to “OFF,” no sound is produced by playing the keyboard. Set Local Control to “ON.”
HP505 only
Could Twin Piano mode be set to “2”?
If headphones are connected when Twin Piano is ON and the mode is set to “2,” notes played in the left-hand keyboard zone will
not be heard from the headphones connected to the right Phones jack. Similarly, notes played in the right-hand keyboard zone
will not be heard from the headphones connected to the left Phones jack.
No sound when you play back
a song
Has Local Control been set to “OFF”?
When Local Control is set to “OFF,” no sound is produced by playing the song. Set Local Control to “ON.”
Could the song volume be set to “0”?
No sound from the left most
notes of the keyboard
Could the Visual Control mode be set to “MVC” or” VLNK”?
If the Visual Control mode is set to “MVC” or “VLNK,” the lowest 12 keys of the keyboard (A0–G#1) are used to control images; they
will not produce sound.
No sound (when a MIDI device is
connected)
Are all devices powered on?
–
Are the MIDI cables connected correctly?
p. 11
p. 12
Do the MIDI channels of the unit and the connected device match?
Notes don’t sound right
Pitch of the keyboard or song is
incorrect
Could you have made Transpose settings?
Is the Master Tune setting appropriate?
Is the setting for the Temperament correct?
If stretch tuning is "ON," the piano will be tuned in a unique way; notes in the piano's upper range will be tuned slightly sharper,
while notes in the lower range will be tuned slightly lower. For this reason, certain pitches may seem to be off, but this is actually
the way that an acoustic piano should sound.
Not all the notes you play are
sounded
The maximum simultaneous polyphony is 128 voices. If you are playing along with a song and making heavy use of the damper
pedal, the number of notes the unit is attempting to produce may exceed the maximum polyphony, meaning that some of the
notes will drop out.
