Press the [Demo Song/Key Touch] button; the button's

The metronome sound or count sound is not recorded.
The recorded performance has been deleted
The performance data that you recorded will disappear
when the power of the HP 237R is turned off (p. 22).
If you record again after recording, the first-recorded
performance will be erased (p. 22).
Sound is distorted
Is the [Volume] knob set to the maximum position? (p. 11)
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. Such phenomenon
becomes more prevalent when sounding the lower
frequencies at high volume. To minimize such unwanted
resonance, please observe the following:
- Locate the instrument so it is 10–15 cm away from
walls.
- Reduce the volume.
- Increase the distance from the object that is
resonating.
If you can hear the problem in the headphones:
The problem may be for a different 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 237R, the range that is unaffected by
the damper pedal will change depending on the Key
Transpose setting.
<When the HP 237R is connected to an
external device>
No sound is produced
Is the power to all equipment turned on?
Are the connections between HP 237R and the MIDI
sequencer or the other external devices correct? (p. 31)
Is the MIDI channel setting correct? (p. 33)
Is the Omni On/Off setting correct? (p. 33)
Strange sounds (or two sounds) are produced
when the HP 237R is played
With the sequencer's "Thru" function on, the same notes
may be sounded twice. Set the HP 237R to Local off
(p. 32).
The volume level of the instrument connected
to the Input jack is too low.
Could you be using a connection cable that contains a
resistor?
Use a connection cable that does not contain a resistor.
