Symptom Cause/Action See Page
The wrong instrument is selected when you
press the [E. Piano], [Strings], or [Others]
button
Tone buttons [E. Piano] [Strings] [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 [E. Piano], [Strings],
and [Others] Tone buttons, so that you can select “recommended” sounds by pressing one of these
buttons.
Eect does not apply
When you are using Dual play or Split play, and dierent eects are specied for the two selected
tones, the eect will not be applied to Tone 2 (when using Dual play) or the left-hand tone (when
using Split play).
P. 32, P. 34
The depth of the reverb eect for the song that’s playing will not change. P. 31
Reverberation remains even if You defeat
the Reverb eect
The HPi-7F’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 eect.
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 dierent
tonal character. HPi-7F faithfully simulate this characteristic of acoustic pianos. On the HPi-7F, the
range that is unaected by the damper pedal will change according to the key transpose setting.
High-pitched ringing is heard
Is the speaker cable connected correctly? P. 14
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 eect 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.
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. Alternatively, lower the master gain.
P. 16, P. 73
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the HPi-7F 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 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.
Pedal does not work, or is “stuck”
Is the pedal connected correctly?
Plug the cable rmly into the pedal connector.
P. 14
If you disconnect the pedal cord from the HPi-7F while the power is on, the pedal eect may remain
“stuck” in the On condition.
You must power-o the HPi-7F before connecting or disconnecting the pedal cord.
Could you have changed how the pedal eect is applied?
If the right pedal part is set to Right, the pedal will apply only to the right tone; if it is set to Left, the
pedal will apply only to the left tone.
P. 73
Could Twin Piano be turned on?
If Twin Piano is on, the right pedal will aect only the right-hand keyboard zone and the left pedal
will aect only the left-hand keyboard zone.
P. 36
Could you have changed the function of the pedal?
If you’ve switched the function of the soft pedal or sostenuto pedal, these pedals will not operate as
the soft pedal or sostenuto pedal.
