rect? (p. 17, p. 18)
The pedals are not functioning, or function inter-
mittently
Are the pedals connected properly? (p. 6)

Did you lock the panel? (p. 19)
Is the [Demo] button's indicator lit? Press the [Demo]

The metronome sound or count-in is never recorded.
The recorded performance has been deleted
The song data that you recorded will disappear when
the power of the HP-237e is turned off (p. 13).
If you record again after recording, the first-recorded
performance will be erased (p. 13).
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
a)
l l 25
HP-237e
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.
* [ncrease 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-237e, the range that is
unaffected by the damper pedal will change depend-
ing on the Key Transpose setting.
When the HP-237e is connected to an
external device
No sound is produced
ls the power to all equipment turned on?
Are the connections between HP-237e and the MIDI
sequencer or the other external devices correct?
(p. 20, p. 21)
Is the MIDI channel setting correct? (p. 23)
Is the Omni On/Off setting correct? (p. 22)
Strange sounds (or two sounds) are produced
when the HP-237e is played
With the sequencer's "Thru" function on, the same
notes may be sounded twice. Switch off the Local
function (p. 22).
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 con-
tain a resistor.
