The wrong instrument is selected
when you press the [E . Piano],
[Strings], or [Other] button
Tone buttons [E. Piano] [Strings] [Other] also operate as buttons that select “Recommended Tones.”
Connecting a commercially-available CD-ROM drive to the USB memory port and selecting a song from a CD-ROM produced for
the VIMA (VIMA TUNES) will automatically cause sounds appropriate for that song to be assigned to the [E. Piano], [Strings], and
[Other] Tone buttons, so that you can select “recommended” sounds by pressing one of these buttons.
Effect does not apply
When you are using Dual play or Split play, and different effects are specified for the two selected tones, the effect will not be
applied to Tone 2 (when using Dual play) or the left-hand tone (when using Split play).

Reverberation remains even if You
defeat the Ambience effect
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 Ambience effect.
Also, you may be able to eliminate some reverberation by reducing the value set for “Cabinet Resonance.”
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 top of the keyboard will continue sounding
regardless of the damper pedal. These notes also have a somewhat different tonal character. The unit faithfully simulate this
characteristic of acoustic pianos. On the unit, the range that is unaffected by the damper pedal will change according to the key
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 character of an actual piano is being faithfully reproduced, and is not a
malfunction.
This sound can be adjusted by modifying the following settings.
• String Resonance (p. 45)
• Ambience (p. 18)
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 a nearby Roland
service center.
–
Low notes 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 the speakers 10–15 cm (4–6 inch) away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
If you hear this in headphones:
It is likely that there is some other reason. Please contact your dealer or a nearby Roland service center.
