Appendices
In the upper range,
the sound changes
abruptly beyond a
certain key
On an acoustic piano, notes in the upper one
and a half octaves of the keyboard continue to
sound until they decay naturally, regardless of
the damper pedal. There is a difference in the
timbre as well. Roland pianos faithfully simu-
late such characteristics of the acoustic piano.
On the HP-7/3, the range that is unaffected by
the damper pedal will change depending on
the Key Transpose setting.
A High-pitched
whine is produced
When listening through headphones:
Some of the more flamboyant and efferves-
cent piano tones feature an ample high-end
component, which may make the sound
appear to have metallic reverberation add-
ed. Since this reverberation becomes par-
ticularly audible when supplemented by
heavy reverb, you may be able to diminish
the problem by reducing the amount of re-
verb applied to the sound.
When listening through speakers:
Here, a different cause (such as resonance
produced by the HP-7/3) would be sus-
pect. Consult your Roland dealer or near-
est Roland Service Center.
Case
Cause/Remedy
The bass range
sounds odd, or
there is a vibrating
resonance
When listening through speakers:
Playing at loud volumes may cause instru-
ments near the HP-7/3 to resonate. Reso-
nation can also occur with fluorescent light
tubes, glass doors, and other objects. In
particular, this problem occurs more easily
when the bass component is increased, and
when the sound is played at higher vol-
umes. Use the following measures to sup-
press such resonance.
• Place speakers so they are 10–15 cm from
walls and other surfaces.
• Reduce the volume.
• Move the speakers away from any reso-
nating objects.

Here, a different cause (such as resonance
produced by the HP-7/3) would be sus-
pect. Consult your Roland dealer or near-
est Roland Service Center.
The volume level of
the instrument con-
nected to Input
jacks is too low
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not contain a
resistor.
