In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 3,
4 and 5, please read and observe the following:
Po w e r Su p p ly
301
Ma in te n a n ce
401b
•
Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
•
To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
307
•
Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/ or damage to speakers or other devices.
402
•
Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/ or
deformation.
Pla ce m e n t
351
Ad d itio n a l Pre ca u tio n s
•
Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-
ference.
553
•
Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
352
556
•
This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
•
When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
354b
•
Do not expose the unit to direct sunlight, place it near
557
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
•
A small amount of heat will radiate from the unit during
normal operation.
558a
•
To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
355
559b
•
•
To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
When you need to transport the unit, pack it in shock-
absorbent material. Transporting the unit without doing
so can cause it to become scratched or damaged, and
could lead to malfunction.
356
•
Do not allow rubber, vinyl, or similar materials to remain
on the piano for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
562
•
Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
357
•
Do not put anything that contains water (e.g., flower
vases) on the piano. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near the
unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
•
Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
358
•
Do not allow objects to remain on top of the keyboard.
This can be the cause of malfunction, such as keys ceasing
to produce sound.
359
•
Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.

Ma in Fe a tu re s o f th e HP 2 3 7 R
Au th e n tic p ia n o p e rfo rm a n ce s
High-quality concert grand piano tones, combined with the Progressive Hammer Action
keyboard, which provides more realistic piano touch, with a heavier feel in the low end
and a lighter feel in the upper notes, let you enjoy truly authentic piano performances.
• Captures the brilliant resonance
The sound of a grand piano has a more brilliant timbre than that of an upright piano.
This is because the sound of a grand piano contains a greater amount of high-frequency
components. The piano sounds of the HP 237R reproduce this characteristic of the grand
piano.
• Reproduces the extended high-frequency response
One of the features of the acoustic piano is that for the approximately one and a half
octaves at the top of the range, there is no damper to restrict the vibration of the strings.
This allows the vibration of the string to continue whether or not the damper pedal is
pressed. Since this also allows these strings to vibrate sympathetically with other strings,
they can sometimes be heard sounding independently from the low and middle-register
strings.
The HP 237R faithfully simulates these characteristics of the acoustic piano.
N in e To n e s fo r u se in a w id e va rie ty o f m u sica l g e n re s
The HP 237R features not only piano tones, but nine different internal tones that you can
use in a variety of musical genres (8 tones + 1 tone [in Split mode]).
Th re e Me tro n o m e so u n d s
The HP 237R provides a metronome that lets you use three different sounds. You can
easily adjust the tempo and time.
Re co rd y o u r o w n p e rfo rm a n ce s
The HP 237R makes it easy to record your own performances.

This pedal softens the sound.
fig.3-01
AC In
Playing with the soft pedal depressed produces a sound that
is not as strong as when otherwise played with the
equivalent strength.
So ste n u to Pe d a l
With the sostenuto pedal, only the sound played at the
moment the pedal is pressed is sustained.
Da m p e r Pe d a l
Use this pedal when you want the sound to linger.
While the damper pedal is depressed, the sound from the
keyboard continues to linger/ remain for an extended period,
even when you remove your fingers from the keys.
On acoustic pianos, when the damper pedal is depressed,
additional strings are released to resonate with the sound of
the keys that have been played, adding richness and breadth
to the sound. The damper pedal on the HP 237R recreates
this resonance when depressed. This resonance is called
“Sympathetic Resonance.”

Do not insert your hands into the inside of the
piano through the space between the lid and
the keyboard.
●●Lower the adjuster so that it is firmly in contact with
the floor. If there is a gap between the adjuster and the
floor, the unit may malfunction when the pedal is
pressed. In particular when the instrument is placed
on a carpeted floor, you must lower the adjuster so
that it presses strongly against the floor.

Take care not to allow fingers to be caught or pinched when
opening and closing the lid. Make sure an adult is on hand to
provide assistance when young children are playing the HP 237R.

Your instrument also allows you to perform using the
tunings that were in use at the time that classical music (such
as Baroque) was composed. Most modern songs are
composed based on assumption that equal-tempered tuning,
the tuning in use almost universally today, will be used
when performing. However, in the age of classical music
there were a variety of different tunings in existence. Try
performing using tunings from those olden times so you can
hear what the chords in certain pieces sounded like
originally.
On acoustic pianos, when the damper pedal is depressed,
additional strings are released to resonate with the sound of
the keys that have been played, adding richness and breadth
to the sound. The damper pedal on the HP 237R recreates
this resonance when depressed. This resonance is called
“Sympathetic Resonance.”
Eight levels of resonance are available.
This is set to “4” when the power is turned on.

Ch a n g in g Tu n in g Cu rve s
When you want to perform using a tuning other than equal
temperament, you’ll need to specify the keynote (tonic for
major, sixth for minor) appropriate for the key of the song
you want to play.
Pianos are commonly tuned so pitches in the lower registers
are adjusted relatively flat, and pitches in the higher registers
are tuned sharper compared to equal temperament. This
kind of tuning method for the piano is called “Stretch
Tuning.”
Key Temperament Description
The graphic representation of the differences in pitch when
comparing equal-tempered tuning with the actual tuning
used is called the “Tuning Curve.” Changing the tuning
curve results in a subtle change in the sound of the chords.
HP 237R can switch the tuning curve.
C4 Equal
With this tuning, the octave is divided
into twelve equal intervals. Regardless
of the interval, very little ambiguity is
produced.
D4 Pythagorean Developed by the philosopher
Pythagoras as a method of tuning that
resolved the ambiguousness of fourths
and fifths. As a result, melodies sound
cleaner, but a certain amount of
ambiguousness is produced with
triads.
“Type 2” (Stretch Tuning) is the power-on default for the
tuning curve.

To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power
on all devices before making any connections.
1 . Turn the volume all the way down on the
HP 237R and on the device you’re about to
connect.

Always make sure to have the volume level turned down before
switching on power. Even with the volume all the way down,
you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.

If you are encountering problems with the unit, please read the section below before assuming that there is a
malfunction.

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:

Is the [Volume] knob set to the minimum position?

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
