Problems with the piano’s sound

No sound

Is the volume turned down? Raise the volume. p. 6

Could headphones or an adaptor

plug be inserted in the Phones jack?

If headphones or an adaptor plug are inserted in the headphones

jack, sound is not output from the speakers. –

If you want sound to be produced from headphones or external speakers, is the device connected correctly? p. 4

Could the “Local Control” setting be

turned “O”? In function mode, turn the “Local Control” setting “On.” p. 26

Pitch of the keyboard or

song is incorrect

Could you have made Transpose

settings? Press the [Transpose] button to cancel transposition. p. 11

Is the Master Tune setting

appropriate?

When shipped from the factory, the reference pitch is set to “442.0

Hz.” Check the “Master Tuning” setting of the Piano Designer function. p. 16

Is the setting for the Temperament

correct?

When shipped from the factory, the tuning is set to “Equal

temperament.” Check the “Temperament” setting of the Piano

Designer function.

p. 17

Is the Single Note Tuning setting

appropriate? Check the Piano Designer function’s “Single Note settings.” p. 18

Sounds are heard twice

(doubled) when the

keyboard is played

Could “Dual Play” be specied, so

that two tones are layered?

Press the [Split/Dual] button several times to make it go dark, exiting

Dual Play. p. 10

Could the piano be connected to an

external sequencer?

If you don’t want the piano to be played from another sound module,

set your music production software’s “soft thru” setting to “O.” –

If the function mode “Local Control” setting is “On,” turn the “Local

Control” setting “O.” p. 26

Reverberation remains

even if you defeat the

Ambience eect

Even if the Ambience eect is o,

the acoustic piano’s own resonance

remains.

You can also reduce the resonance by lowering the “Cabinet

Resonance” value of the Piano Designer function. p. 18

The sound of the higher

notes suddenly changes

from a certain key

This simulates the characteristics of an acoustic piano, and is not a malfunction.

The sound will change where there is a change in the number of strings per key or a transition from wound

strings to unwound strings.

–

When you press a key,

the sound of a note you

didn’t press is also faintly

heard

In some cases, a note you play

might cause a dierent note (whose

frequency is an integer multiple of

the rst note) to resonate, producing

the sensation that the sound has

changed; this is not a malfunction.

Lower the Piano Designer’s “Full Scale String Res.” value, or turn it o. p. 18

A buzz or vibration

occurs when you play the

keyboard

This feature simulates the vibration

that occurs when you play the

keyboard of an acoustic piano; it is

not a malfunction.

You can eliminate the keyboard vibration by turning the “Haptic Key

Vibration” setting o in function mode. p. 27

High-pitched ringing is

heard

If you don’t hear it through headphones:

It may be that the piano has malfunctioned. Please contact your dealer or a Roland customer service center.

If you also hear it through headphones:

To decrease the metallic ringing, adjust the following settings.

5Ambience (p. 16)

5Full Scale String Res. (p. 18)

–

Low notes sound wrong,

or are buzzy

Could the volume be set to

maximum?

If the volume is at the maximum, the sound might be distorted

depending on how you play the piano. If this occurs, lower the

volume.

p. 6

If you also hear it through headphones:

It may be that the piano has malfunctioned. Please contact your dealer or a Roland customer service center.

If you don’t hear it through headphones:

Objects near the piano are resonating because of the high volume of sound coming from the speakers. You

can take the following measures to minimize resonances.

5Keep the volume down.

5Locate the speakers 10–15 cm (4–6 inch) away from walls or other surfaces.

5Move away from the objects that are resonating.

–

Noise is sometimes heard when

you change the master tuning

or temperament while piano

sound is being produced

Due to the structure of the sound engine, noise might be heard for concert grand sounds if you change the

master tuning or temperament while sound is being produced, but this is not a malfunction. –

The sound is heard

dierently depending on

the tone settings

When using “Dual play” which layers two tones, or “Split play” which produces dierent tones in the left-

hand and right-hand, the sound might be heard dierently depending on the specic combination. For

some combinations, the eect is not applied to the left-hand tone or to tone 2, but this is not a malfunction.
