❍Is the Master Tuning setting correct? (p. 26)

❍Is the Key Transpose setting correct? (p. 25)

❍Is the temperament or the Tuning Curve setting correct? (p. 28, p. 29)

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.

The pedals are not functioning, or function intermittently

❍Are the pedals connected properly?

Make sure the pedal cord is securely connected to the pedal jack on the back of the unit.

Can’t Record

❍Is Panel Lock on? (p. 30)

❍Is the [Demo Song/Key Touch] button’s indicator lit? Press the [Demo Song/Key Touch] button; the button’s indicator goes out (p. 13).

❍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)

<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.
