IMPORTANT NOTES

291b

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:

Power Supply

301

• 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).

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.

Placement

351

• 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.

352

• This device may interfere with radio and television

reception. Do not use this device in the vicinity of such

receivers.

354b

• Do not expose the unit to direct sunlight, place it near

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.

355

• To avoid possible breakdown, do not use the unit in a wet

area, such as an area exposed to rain or other moisture.

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.

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.

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.

Maintenance

401b

• 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.

402

• Never use benzine, thinners, alcohol or solvents of any

kind, to avoid the possibility of discoloration and/or

deformation.

Additional Precautions

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.

556

• 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.

557

• 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).

559b

• 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.

562

• Use a cable from Roland to make the connection. If using

some other make of connection cable, please note the

following precautions.

• 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.

Main Features of the HP 237R

Authentic piano performances

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.

Nine Tones for use in a wide variety of musical genres

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]).

Three Metronome sounds

The HP 237R provides a metronome that lets you use three different sounds. You can

easily adjust the tempo and time.

Record your own performances

The HP 237R makes it easy to record your own performances.

Button Descriptions

Button, switch and knob names are enclosed in square brackets ( [ ] ).

Opening and Closing the Lid

fig.3-03

When opening the HP 237R’s lid, grasp the

lid with both hands and gently lift it

upwards, then slide it towards the back of

the piano.

2. When closing the lid, slowly pull the lid

forward, then gently lower it into place.

Do not insert your hands into the inside of the

piano through the space between the lid and

the keyboard.

NOTE

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.

NOTE

For safety, transport the keyboard only with the lid in the closed

position.

About the Pedals

fig.3-04.e

Soft Pedal

This pedal softens the sound.

Playing with the soft pedal depressed produces a sound that

is not as strong as when otherwise played with the

equivalent strength.

Sostenuto Pedal

With the sostenuto pedal, only the sound played at the

moment the pedal is pressed is sustained.

Damper Pedal

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.”

You can change the amount of resonance applied with the

damper pedal. For more information and instructions, please

refer to “Changing the Damper Pedal’s Resonance” (p. 28).

About the Adjuster

After you have moved this piano, or when you feel it is

unstabled, lower the adjuster at the bottom of the pedal

board as follows:

❍ 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.

Using Two Different Sounds for Right And Left

Hands–Split Function

The piano allows you to divide the keyboard into two sections, upper and lower, and to

play two different Tones. Dividing the keyboard is called “Split” and the key where the

keyboard is split is called the “Split Point”.

The Split Point is at “F3” when the power is turned on.

fig.5-20-1

1. Hold down the Tone button for the sound that you want to include

in the split, and press the Metronome [Sound] button.

The indicator on the Tone button you have pressed will flash.

Play the keyboard and hear that two different sounds are played in the upper and lower

sections.

The sounds will be assigned to the keyboard as follows:

* Chorus (p. 19) cannot be applied to the tones with Acoustic Bass.

* The pedal will have no effect on what is played in the lower section of the keyboard.

2. To cancel Split, press a Tone button with an indicator that is

extinguished.

The selected tone is effective for the entire keyboard.

Changing the Split Point

When you are using the Split function, you can change the location at which the

keyboard is split (the Split Point).

Hold down the Tone button whose indicator is blinking, and press

the note that you wish to use as the new Split Point.

The Split Point can be set from B1–B6.

The key that serves as the split point is included in the lower section.

The Split Point you set will be retained until the piano is switched off.

Adding Breadth to the Sound–Chorus Effect

The HP 237R allows you to add chorus to what you play on the keyboard.

By adding the Chorus Effect, you can give the sound greater dimension, with more

fatness and breadth.

The settings of the Chorus Effect are memorized independently for each sound.

When the power is turned on, the Chorus Effect will be applied to the “Electric Piano 1”,

“Electric Piano 2” and “Vibraphone” sounds. The Chorus Effect will be turned off for the

other sounds.

fig.5-06

1. Press the [Chorus] button to turn on the indicator.

The Chorus Effect will be applied to the currently selected sound.

fig.5-07.e

When you select a sound for which the Chorus Effect has not been turned on, the

[Chorus] button indicator will go dark.

2. To cancel the Chorus Effect, press the [Chorus] button once again

to make the indicator go dark.

fig.5-08.e

While using the Dual (p. 16) or Split (p. 17) functions, lighting/extinguishing the

[Chorus] button’s indicator will switch the Chorus Effect on/off for both sounds.

(However, when Split is being used, the Chorus Effect will not be applied to the

Acoustic Bass.)

After Dual or Split is cancelled, the piano reverts to the Chorus Effect setting that

a particular sound normally carries.

The on/off status of the [Chorus] button is not remembered when Dual or Split are

used.

The amount of Chorus can be changed. Please refer to “Changing the Depth of the

Chorus” (p. 27).
