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
simulate such characteristics of the acoustic
piano. On the MP-60, the range that is unaf-
fected by the damper pedal will change de-
pending on the Key Transpose setting.
A High-pitched
whine is produced
When listening through headphones:
Some of the more flamboyant and effer-
vescent piano tones feature an ample
high-end component, which may make
the sound appear to have metallic rever-
beration
added. Since this reverberation becomes
particularly audible when supplemented
by heavy reverb, you may be able to di-
minish the problem by reducing the
amount of reverb applied to the sound.
When listening through speakers:
Here, a different cause (such as resonance
produced by the MP-60) 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 in-
struments near the MP-60 to resonate.
Resonation can also occur with fluores-
cent light tubes, glass doors, and other ob-
jects. In particular, this problem occurs
more easily when the bass component is
increased, and when the sound is played
at higher volumes. Use the following mea-
sures to suppress such resonance.
• Place speakers so they are 10–15 cm
from walls and other surfaces.
• Reduce the volume.
• Move the speakers away from any
resonating objects.
When listening through headphones:
Here, a different cause (such as resonance
produced by the MP-60) 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.
