HP-1
Owner’s Manual
Thank you for purchasing a Roland HP-1 Digital Piano. The HP-1 is the new entry-level model of Roland’s HP series
Digital Pianos. As such, it comes with all the benefits: a weighted Hammer-Action keyboard, vibrant sounds and a num-
ber of useful functions.
Authentic piano performances
Eight Tones for a wide variety of musical genres
The HP-1 comes with eight sounds (called “Tones”).
That way, you can also use your instrument for play-
ing harpsichord, organ, and pop/jazz music.
A high-quality concert grand piano sound, and a key-
board that’s a true pleasure to play ensure an even
more realistic piano-playing experience. Thanks to its
Hammer-Action keyboard, the HP-1 faithfully repro-
duces the feel of an acoustic piano with minute con-
trol over the sound.
Before using this instrument, carefully read the sec-
tions on pages 2 and 4. They provide important infor-
mation concerning the proper operation of the HP-1.
Captures the brilliant resonance
The sound of a grand piano has a brilliant timbre
because it contains a greater amount of high-fre-
quency components. The HP-1 reproduces this char-
acteristic of the grand piano.
To get the most out of the HP-1 and to ensure many
years of trouble-free service, we urge you to read
through this Owner’s Manual thoroughly.
To avoid confusion, let’s agree to use the word “but-
ton” for all keys on the front panel, and only use “key”
when referring to the HP-1’s keyboard.
Extended high-frequency response
One of the features of an acoustic piano is that for the
strings of the highest 1 1/2 octaves, there is no damper
to restrict the vibration of the strings, irrespective of
whether or not the damper pedal is used. 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-1 faithfully simulates these characteristics of
the acoustic piano (being a digital instrument, the
HP-1 contains no strings, however).

1. Important notes
Power Supply
Maintenance
• 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.
• Before connecting the HP-1 to other devices, turn off
the power to all units. This will help prevent malfunc-
tions and/or damage to speakers or other devices.
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Placement
• Using the unit near power amplifiers (or other equip-
ment containing large power transformers) may
induce hum. To alleviate the problem, change the ori-
entation of this unit; or move it farther away from the
source of interference.
Additional Precautions
• Use a reasonable amount of care when using the
HP-1’s buttons, sliders, or other controls; and when
using its jacks and connectors. Rough handling can
lead to malfunctions.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• When connecting/disconnecting 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.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicin-
ity of this unit. Such noise could occur when receiving
or initiating a call, or while conversing. Should you
experience such problems, you should relocate such
wireless devices so they are at a greater distance from
this unit, or switch them off.
• A small amount of heat will radiate from the unit dur-
ing normal operation.
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels. You may prefer to
use headphones.
• Do not expose the instrument to direct sunlight, place
it near devices that radiate heat, leave it inside an
enclosed vehicle, or otherwise subject it to tempera-
ture 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 spot-
lights to shine upon the same area of the unit for
extended periods of time. Excessive heat can deform
or discolor the unit.
• 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.
• 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 information on cable specifications, con-
tact the manufacturer of the cable.
• To avoid possible breakdown, do not use the HP-1 in a
wet area, such as an area exposed to rain or other
moisture.
• Do not allow rubber, vinyl, or similar materials to
remain on the HP-1 for long periods of time. Such
objects can discolor or otherwise harmfully affect the
finish.
• 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.
• Do not allow objects to remain on the keyboard. This
can be the cause of malfunction, such as keys ceasing
to produce sound.
• Do not paste stickers, decals, or the like to this instru-
ment. Peeling such matter off the instrument may
damage the exterior finish.

3. Main operations
Note: 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.
About the adjuster
When you move the HP-1 or if you feel that the pedals
are unstable, adjust the adjuster located below the
pedals as follows.
Rotate the adjuster to lower it so that it is in firm con-
tact with the floor. If there is a gap between the pedals
and the floor, the pedals may be damaged. In particu-
lar when placing the instrument on carpet, adjust this
so that the pedals firmly contact the floor.
3.1 Connecting the power cord
Connect the supplied power cord to a wall outlet.
Adjuster
Note: Strong tension applied to the cord may damage or
break it. Be careful not to pull the cord accidentally, or to
apply strong pressure to it.
3.3 Setting up the music stand
Set up the music stand as shown in the figure below.
3.2 About the pedals
The HP-1 comes with two pedals that are built into
the supplied stand:
Soft pedal
Damper pedal
Fold out the three supporting feet at the back of the
stand and check whether the stand is held in place.
Soft pedal– This pedal softens the sound. Playing with
the soft pedal depressed produces a sound that is not
as strong as when played with the equivalent strength.
This is the same function as the left-most pedal on an
acoustic piano.
Note: You can change the left pedal’s function. See (p. 16).
Damper pedal– Use this pedal when you want the
sound to linger on. While the damper pedal is
depressed, the sound from the keyboard continues to
linger for an extended period, even when you remove
your fingers from the keys.
This is the same function as the right-most pedal on
an acoustic piano.
Note: Before moving the HP-1, be sure to lower the music
stand as a safety precaution.

4.2 Transposing (same fingering, different notes)
You can play in a different key while still using exactly the same fingering. That way, even songs originally written in a
difficult key with many ꢀ (sharps) or ꢁ (flats) (i.e. with many black keys), can be played in a more convenient way. This is
especially useful when you are used to playing a given song in one key, while someone else wants you to play it in
another key: just change the Transpose setting and you’re there.
The transposition remains in effect until you change it or until you switch off the HP-1.

HP-1 – Owner’s Manual
4.3 Master Tuning
When playing in ensemble with other instruments, you can adjust the HP-1’s reference pitch to that of another instru-
ment.
Middle A (“A4”) is generally used for adjusting the tuning of the instruments. When playing in ensemble with other
instruments, tune each instrument to the same reference pitch. “440Hz” is the power-on default for the reference pitch.
The following operations only work after selecting the HP-1’s Function mode (see p. 12 for how to select it).
Sounding the A4 note
Returning to 440Hz
While tuning, it is of utmost importance to compare
the HP-1’s tuning with that of the external instrument
or device. Since the keyboard is used for setting the
Function parameters, it is no longer available for play-
ing that note the normal way.
Press the “A1” key on the keyboard.
That is why there are six keys that allows you to sound
the A4 note. These are the first six keys in the tuning
range indicated on p. 12:
Return to 440Hz
The reference pitch will be set to 440.0 Hz. This is the
most commonly used setting.
Setting the reference pitch to 442Hz straight
away
“442Hz” is a popular tuning pitch for concert grands.
Rather than trying to set it using the “G1” and “G#1”
keys, you can press the “A#1” key to select that tuning
right away:
Press these keys to sound the
A4 note.
Lowering/ raising the reference pitch
The following keys (“G1” and “G#1”) can be used for
lowering or raising the HP-1’s pitch in very small
steps:
Higher
Select 442Hz
The standard pitch will be set to 442Hz, and all other
notes will change accordingly.
Lower
Press the “G1” note to lower the reference pitch, or
the “G#1” note to raise it.
Each time you press the “G1” key, the pitch will fall by
0.1 Hz. If you continue holding the key, the pitch will
continue falling.
Each time you press the “G#1” key, the pitch will rise
by 0.1 Hz. If you continue holding the key, the pitch
will continue rising.

Convenient functions
4.4 Changing the temperament
You can play classical styles such as Baroque using historic temperaments (tuning methods).
Today, compositions are generally created with equal temperament in mind and are played using equal temperament.
However in past ages of classical music, a variety of temperaments were used. Playing a composition with its original
tuning lets you enjoy the sonorities of the chords that the composer originally intended.
1. Simultaneously press [Demo] and [Reverb] to
enter Function mode (both indicators flash).
Tonic
When playing with tuning other than equal tempera-
ment, you need to specify the keynote for tuning the
song to be performed (that is, the note that corre-
sponds to C for a major key or to A for a minor key).
2. Use the “F3”~”B3” keys to select the temperament:
While still in Function mode, press the key that corre-
sponds to the desired tonic:
F3
(See p. 12 for the exact location of these keys.)
You can choose from among the seven temperaments
described below.
Press to select C as tonic
[F3] Equal temperament– In this tuning, each octave is
divided into twelve equal steps. Every interval pro-
duces about the same amount of slight dissonance.
This setting is in effect when you turn on the power.
If you choose an equal temperament, there’s no need
to select a keynote.
Note: When performing with other instruments, be aware
that depending on the key, there may be some shifting of the
pitch. Tune the HP-1 to the fundamental pitch of the other
instruments.
[F#3] Pythagorean– This tuning, devised by the philos-
opher Pythagoras, eliminates dissonance in fourths
and fifths. Dissonance is produced by third-interval
chords, but melodies are euphonious.
3. Press [Demo] and [Reverb] again to leave the
HP-1’s Function mode.
[G3] Just (major)– This tuning eliminates ambiguities in
the fifths and thirds. It is unsuited to playing melodies
and cannot be transposed, but is capable of beautiful
sonorities.
[G#3] Just (minor)– The Just tunings differ from major
and minor keys. You can get the same effect with the
minor scale as with the major scale.
[A3] Mean Tone– This scale makes some compromises
in just intonation, enabling transposition to other
keys.
[A#3] Werckmeister– This temperament combines the
Mean Tone and Pythagorean tunings. Performances
are possible in all keys (first technique, III).
[B3] Kirnberger– This is an improvement of the Mean
Tone and Just tunings that provides a high degree of
freedom of modulation. Performances are possible in
all keys (III).
Initial setting: Equal temperament

4.5 Selecting the tuning curve (Stretch Tuning)
A piano is generally tuned to a pitch with a lower bass range and a higher treble range than equal temperament. This
special tuning method for pianos is called “Stretch Tuning.”
1. Simultaneously press [Demo] and [Reverb] to
(See p. 12 for the exact location of these keys.)
enter Function mode (both indicators flash).
[A7] Off– This is the standard tuning curve. This is the
right choice when using Dual performance (p. 10), or
when playing in ensemble with other instruments.
2. Use the “A7” or “A#7” key to switch the Stretch
Tuning function on or off.
[A#7] On– This tuning curve expands the bass and tre-
ble ends somewhat. It is suitable for performances
such as piano solos. This setting is in effect when you
turn on the power.
Stretch Tuning on
This effect works only with the piano tones.
3. Press [Demo] and [Reverb] again to leave the
HP-1’s Function mode.
Stretch Tuning off
4.6 Setting the key touch
Your HP-1 also provides a function that allows you to adapt it to your playing style, or to ensure that even your children
can play loud notes. The are four “Key Touch” levels that can be selected once you have called up the Function mode
(p. 12):
Press one of the keys labeled“Key Touch” to select the
desired level.
Light: Little strength is required to play at high vol-
umes.
Medium: The keyboard reacts normally (similar to an
acoustic piano).
Heavy: Choose this only if you usually strike with too
much force and therefore play very bright/loud notes.
This is also a good setting for practising purposes.
Fixed: The timbre (tone color) and volume are the
same for all notes. The HP-1 is therefore no longer
touch sensitive. This setting is probably only useful for
the “Organ 1” and “Organ 2” sounds.
Note: Though “Light” may be a good settings for beginners,
they should also try to get used to playing with the
“Medium” setting.
Note: At power-on, the HP-1 selects the “Medium” setting.

Convenient functions
4.7 Changing the damper pedal’s resonance
On an acoustic piano, depressing the damper pedal makes the notes you play resonate with other strings, adding rich
reverberations and fatness to the sound. The damper pedal on the HP-1 recreates this resonance (Sympathetic Reso-
nance) when depressed.
You can select from eight levels of depth for the reso-
nant sound (resonance level) and even switch it off.
(See p. 12 for the exact location of these keys.)
Use the “C2”~”G2” keys to set the desired Sympa-
thetic Resonance level.
This setting is valid only for some piano tones. It can-
not be made for other Tones.
Press the“B1” key (leftmost key of the range) if you do
not need this effect.
1. Simultaneously press [Demo] and [Reverb] to
enter Function mode (both indicators flash).
3. Press [Demo] and [Reverb] again to leave the
HP-1’s Function mode.
2. Use the following keys to select the desired Sympa-
thetic Resonance setting:

4.8 Selecting the function of the left pedal
Grand pianos (and upmarket-models of the Roland HP series) have three pedals instead of two. This means that, in
addition to the Damper and Soft pedals mentioned on p. 7, there is also a Sostenuto pedal.
On the HP-1, you can assign this function to the left pedal, in which case the Soft function is no longer available.
Sostenuto pedal– If you select this function, the left
pedal allows you to sustain the notes you played at the
time when you pressed the pedal. Subsequently played
notes, however, will not be held.
(See p. 12 for the exact location of these keys.)
3. To once again select the Soft function:
• Either press the “F#7” key;
1. Simultaneously press [Demo] and [Reverb] to
enter Function mode (both indicators flash).
2. Press the “F7” key to select the Sostenuto function.
• Or switch the HP-1 off and back on again.

5. Connecting to MIDI devices
By connecting an external MIDI device and exchanging performance data, you can control the performances on one
device from the other. For instance, you can output sound from the other instrument or switch Tones on the other
instrument.
MIDI stands for Musical Instrument Digital Interface, an international standard which allows performance information
to be communicated among electronic musical instruments and computers.
The HP-1 provides MIDI connectors, which allow performance data to be exchanged with external devices. When these
connectors are used to connect the HP-1 to external devices, an even wider range of possibilities becomes available.
Switch off the Local Control function if you have con-

your MIDI sequencer to MIDI Thru mode (so that
messages received at MIDI IN will be re-transmitted
without change from MIDI OUT). For details, refer to
the owner’s manual of your MIDI sequencer.

MIDI features sixteen MIDI channels, numbered
1~16. Simply connecting a cable is not enough for
communication to take place. The connected devices
must be set to use the same MIDI channels. Other-
wise, no sound will be produced, and no sounds can
be selected.
Note: The HP-1 receives on all channels 1~16.

Connecting to MIDI devices
5.2 Switching Local Control on and off
When connecting a MIDI sequencer, switch off the Local Control function.
As illustrated, information describing what has been
played on the keyboard is passed to the internal sound
generator over two different routes, (1) and (2). As a
result, you hear overlapping or intermittent sounds.
To prevent this from happening, route (1) must be
severed, by setting the unit to what is known as “Local
Off.”
Local Control off: The keyboard and the internal
sound generator are in an unlinked state. No sound
will be produced by the keyboard when it is played.

7. Appendix
7.1 Troubleshooting
If you are encountering problems with the HP-1, please read the section below before assuming that there is a malfunc-
tion.
The piano cannot be switched on
Is the power cord properly connected? (p. 7)
• Increase the distance from the object that is resonat-
ing.
If you can hear the problem in the headphones, there
No sound is produced
may be another reason. Please contact your dealer.
Is the volume knob set to the minimum position?
(p. 8)
In the upper range, the sound changes abruptly
beyond a certain key
Are headphones connected? (p. 8)
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-1, the range that is unaf-
fected by the damper pedal depends on the Key Trans-
pose setting.
Did you switch off the Local function? (p. 18)
The pitch of the keyboard sounds incorrect
Is the Master Tuning setting correct? (p. 13)
Is the Transpose setting correct? (p. 12)
Did you select another temperament? (p. 14)
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. This becomes more
noticeable when sounding the lower frequencies at
high volume. To minimize such unwanted resonance,
please observe the following:
When the HP-1 is connected to an external device
No sound is produced
Is the power to all equipment turned on?
Are the connections between the HP-1 and the MIDI
sequencer or the other external devices correct?
(p. 17)
• Locate the instrument at least 10~15 cm away from
the walls.
Is the MIDI channel setting correct? (p. 17)
• Reduce the volume.
