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 HP-2, 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 
added. Since this reverberation becomes 
particularly audible when supplemented 
by heavy reverb, you may be able to dimin-
ish 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 HP-2) 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 instru-
ments near the HP-2 to resonate.
Resonation 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 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 HP-2) would be suspect. 
Consult your Roland dealer or nearest 
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.
