Troubleshooting
Notes don’t sound right
Pitch of the keyboard or song is
incorrect
Could you have made Key Transpose settings?
Is the Master Tune setting appropriate?
Is the setting for the Temperament correct?
Sounds are heard twice (doubled)
when the keyboard is played
Is the DP-990 in Dual performance?
When the DP-990 is connected to an external sequencer, set the Local Control
to off. Alternatively, the sequencer could be set so its Soft Thru feature is Off.
The wrong instrument is selected
when you press the [Strings],
[Voice], or [Others] button
INSTRUMENT buttons [Strings] [Voice] [Others] also operate as buttons that
select “Recommended Tones.”
With the factory settings, connecting a commercially-available CD-ROM drive
to the external memory connector 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 [Strings], [Voice], and [Others]
Tone buttons, so that you can select “recommended” sounds by pressing one
of these buttons.
You can also make settings so that “recommended” sounds are not
automatically assigned.
Effect does not apply
When you are using Dual performance or Split performance, and different
effects are specified for the two selected tones, the effect will not be applied
to Tone 2 (when using Dual performance) or the left-hand tone (when using
Split performance).

Reverberation remains even if
you defeat the Reverb effect
The DP-990’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 effect.
* Lowering the Key Off Resonance (p. 72) may improve matters.

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. DP-990
faithfully simulate this characteristic of acoustic pianos. On the DP-990, 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 ringing is more obtrusive if the
reverb effect 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 a nearby Roland service center.
