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 MP-70, 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 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 sup-
plemented by heavy reverb, you may be
able to diminish 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-70) would be
suspect. Consult your Roland dealer or
nearest 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
instruments near the MP-70 to resonate.
Resonation can also occur with fluores-
cent 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 volumes. Use the following
measures 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-70) would be
suspect. Consult your Roland dealer or
nearest Roland Service Center.
The volume level
of the instrument
connected 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.
