7.1 Troubleshooting
If you are encountering problems with the HP-1, please read the section below before assuming that there is a malfunc-
tion.
The piano cannot be switched on
Is the power cord properly connected? (p. 7)
No sound is produced
Is the volume knob set to the minimum position?
(p. 8)
Are headphones connected? (p. 8)
Did you switch off the Local function? (p. 18)
The pitch of the keyboard sounds incorrect
Is the Master Tuning setting correct? (p. 13)
Is the Transpose setting correct? (p. 12)
Did you select another temperament? (p. 14)
Bass notes sound wrong/buzzing or vibration occurs
If you can’t hear the problem in the headphones: When
playing at high volumes, resonance may occur in the
piano itself or in objects near the piano. At times,
other objects in the room, such as fluorescent lights or
glass doors, could start vibrating. This becomes more
noticeable when sounding the lower frequencies at
high volume. To minimize such unwanted resonance,
please observe the following:
• Locate the instrument at least 10~15 cm away from
the walls.
• Reduce the volume.
• Increase the distance from the object that is resonat-
ing.
If you can hear the problem in the headphones, there
may be another reason. Please contact your dealer.
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-1, the range that is unaf-
fected by the damper pedal depends on the Key Trans-
pose setting.
When the HP-1 is connected to an external device
No sound is produced
Is the power to all equipment turned on?
Are the connections between the HP-1 and the MIDI
sequencer or the other external devices correct?
(p. 17)
Is the MIDI channel setting correct? (p. 17)
