Reverberation remains
even if you defeat the
Ambience effect
Even if the Ambience effect is off,
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 different note (whose
frequency is an integer multiple of
the first 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 off.
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 off in function mode.
p. 27
High-pitched ringing is

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.
5
Keep the volume down.
5
Locate the speakers 10–15 cm (4–6 inch) away from walls or other surfaces.
5
Move away from the objects that are resonating.
–
The sound is heard
differently depending on
the tone settings
When using “Dual play” which layers two tones, or “Split play” which produces different tones in the left-
hand and right-hand, the sound might be heard differently depending on the specific combination. For
some combinations, the effect is not applied to the left-hand tone or to tone 2, but this is not a malfunction.
