Roland HP103 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 
simulate such characteristics of the acoustic 
piano. On the HP103, 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 
effervescent 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 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 HP103) would be suspect. 
Consult your Roland dealer or nearest 
Roland Service Center.

 

The bass range 

sounds odd, or 

there is a vibrating 

resonance

 

When listening through speakers: 

Playing at loud volumes may cause 
instruments near the HP103 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 
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 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.

Error messages are indicated by an “E.” before the number. Press any button, and you can cancel the error message.

 

 

The “.” in the display indicates that there is performance material already 
recorded (p. 31).

 

 

This appears when a song with a pickup (a song that does not start on the first 
beat) is played back.

 

 

The amount of performance information is too large, and further recording is 
not possible.

 

A problem such as a loose MIDI cable occurred. Make sure the MIDI cables 
are correctly hooked up.
