Roland HP-7/3 用户手册

 

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.

 

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.

produced by the HP-7/3) would be sus-

The volume level of 

the instrument con-
