Quick Operations

Hold down the [] (settings) button and press the keys to switch between the various functions.

Select a tone		Press one key to select a single tone that plays with each key press. Press two keys at the same time to select two different tones that play together with each key press. This function is called "Dual Play".
Select a song		Select the built-in song category.
		Select either a song on the USB flash drive, or a song recorded in internal memory.
		Select the song to play back. "Internal Song List"
Play back or stop a song		Play back all of the songs within the category, or just one. Press the same key again to stop playback.
Specifying the keyboard tone for song playback (SMF play mode)		Normally you will use the "Auto-Select" setting.
		Setting	Explanation
		Auto-Select (default)	Either "Internal" or "External" is selected automatically depending on the song that you play back.
		Internal	The tone for the song that plays back and the tone you use when playing the keyboard are the same. The tone for the song changes when you change the tone on the GP-3. We recommend this setting when playing the built-in songs. The damper resonance (*1) effect is applied to the piano tone for the song.
		External	A different tone can be used for the song that plays back and for the tone you use when playing the keyboard. The tone for the song doesn't change when you change the tone on the GP-3. We recommend this setting when playing back song files from your computer connected via USB. The damper resonance (*1) effect is not applied to the piano tone for the song.
		(*1) This refers to the overall resonance of the acoustic piano when its damper pedal is pressed (the sound of other strings vibrating in sympathy when you press the damper pedal, and the resonance of the entire instrument).
Bluetooth settings		Turn Bluetooth on to connect to the "Roland Piano App" app. (Default value: On) "Connecting the Piano and a Mobile Device via Bluetooth"
Start and stop the metronome		The metronome switches on/off with each key press.
Change the metronome's volume		1–10 (default value: 5)
Change the time signature		0/4 (*2), 2/4, 3/4, 4/4, 5/4, 6/4, 7/4 (default value: 4/4) (*2) Each beat plays with the same sound when the metronome plays.
Change the tempo		10–500 (default: 108)
Add ambience to the sound (Ambience)		The reverberation that is characteristic of a performance in a concert hall can be added to the sound. Higher values produce deeper ambience; lower values produce shallower ambience. 0–10 (default value: 1)
Make the ambience sound natural when using headphones ( Piano Reality Headphones Ambience )		You can apply a Piano Reality Headphones Ambience effect that creates the impression that the sound is being heard from the piano itself even when you're using headphones. (Default value: On) * The Piano Reality Headphones Ambience effect applies only to piano sounds; it does not apply to other sounds.
Adjust the brightness of the sound (Brilliance)		You can adjust the brightness of the sound when you play the keyboard or when you play back a song. Higher values produce brighter sounds. -10–+10 (default value: 0)

Split the keyboard into two zones (Twin Piano)		You can divide the keyboard into left and right zones so that two people can play within the same pitch range. Use this when you want it to sound like two pianos are being played. This splits the keyboard into two zones (left and right), centered around middle C (C4). Select between three ways of playing the sounds.
		Setting	Explanation
		Off (default value)	Cancels the setting for splitting the keyboard.
		Pair	Notes played in the right zone are louder in the right speaker; notes played in the left zone are louder in the left speaker.
		Individual	Notes played in the right zone are heard only from the right speaker; notes played in the left zone are heard only from the left speaker.
		* The left and right tones are the same (concert piano). * The damper pedal works only for the right-side keyboard zone. The soft pedal operates as a damper pedal for the left side.
Change the key touch (Key Touch)		Sets the key touch when you are playing the keyboard.
		Setting	Explanation
		Very heavy	A heavier setting than "heavy".
		Heavy	With this setting, the keys must be played with more force than the "Standard" setting to achieve fortissimo (ff ) levels, so the keyboard action feels heavier.
		Standard (default)	A "standard" key touch that is closest to that of an acoustic piano.
		Light	With this setting, you can achieve fortissimo (ff ) levels by playing with less force than the "Standard" setting, so the keyboard action feels lighter.
		Very light	A lighter setting than "Light".
		Fixed	The keyboard always plays notes at the same strength, regardless of how hard or soft you play.
Match the tuning to another instrument (Master Tuning)		When playing in an ensemble or other situations with other instruments, you can adjust the reference pitch of this piano to match its tuning with other instruments. The reference pitch is usually expressed as the frequency that is heard when you play the "middle A (A4)" note. When performing in an ensemble with other instruments, the instruments should all be tuned to the same reference pitch for a satisfying sound. The action of matching the reference pitch to other instruments is called "tuning". 415.3 Hz–466.2 Hz (default: 442.0 Hz)
Transpose (Transpose)		The keyboard can be transposed in semitone steps. When accompanying a vocal, or when performing as a singer-instrumentalist, you can transpose the pitch to match the singer's pitch range without changing the fingering of your keyboard playing. -6–5 (default value: 0)
Export recorded songs		You can export the songs that are recorded in the piano's internal memory to a USB flash drive. "Recording Your Performance"
Change the volume (Song Volume)		Adjusts the volume of the song that's playing. 1–10
(USB Audio/Bluetooth Volume)		Adjusts the volume of the audio signal received via Bluetooth or the USB Computer port. 1–10 (default value: 7)
Making the power automatically turn off after a time (Auto Off)		The power automatically switches off 30 minutes after you stop playing or operating this instrument (at factory settings). If you don't want the power to turn off automatically, change the "Auto Off" setting to "Off" as follows. Off, 10, 30, 240 (min.); default: 30 min.

Before You Play

Opening/Closing the Keyboard Cover

Make sure to use both hands when closing or opening the keyboard cover.
* When opening or closing the keyboard cover, take care not to pinch your fingers between the moving part and the piano unit. In places where small children are present, make sure that an adult provides supervision and guidance.

Opening the Keyboard Cover

Use both hands to lift up the edge of the cover, and push it away from you.

* Do not open the cover with objects (such as paper or metal items) lying on top. This might cause the objects to be pushed inside the piano unit, and you may not be able to retrieve them.

Closing the Keyboard Cover

Hold the cover with both hands and gently pull it towards you.

Using the Music Rest

Stabilizing the Music Rest

Considerably loosen the screws that fasten the music rest (so that they almost come out), and hook the bottom part of the music rest into the gap between the screws and the piano. While holding the music rest with one hand, use your other hand to turn the screws and stabilize the music rest.

* When attaching, firmly insert the music rest as far as it can go, and grip it with your hand so that it doesn't fall over. Take care not to get your hand pinched. Be careful not to scratch the body of the piano with the metal parts.
* Do not apply excessive force to the music rest.
* When removing the music rest, loosen the screws while holding it with one hand. After you remove the music rest, firmly retighten the screws.

Troubleshooting

Problem	Items to check	Cause/Action
Problems with the piano's sound
No sound	Is the volume turned down?	Raise the volume.
	Could headphones or an adaptor plug be inserted in the Phones jack?	If headphones or an adaptor plug are inserted in the headphones jack, sound is not output from the speakers.
	If you want sound to be produced from headphones, is the device connected correctly?
	Could you have made Transpose settings?	Disable transpose in the Transpose settings.
Pitch of the keyboard or song is incorrect	Is the Master Tune setting appropriate?	When shipped from the factory, the reference pitch is set to "442.0 Hz". Check the Master Tuning settings.
Sounds are heard twice	Could "Dual Play" be specified, so that two tones are layered?	Hold down the [] (settings) button and press the A0 key to exit Dual Play mode.
(doubled) when the keyboard is played	Could the piano be connected to an external sequencer?	If you don't want the piano to be played from another sound module, set your music production software's "soft thru" setting to "Off".
Reverberation remains even if you defeat the Ambience effect	This simulates the depth and ambience of the acoustic piano's sound, and is not a malfunction. Even if the Ambience effect is off, the acoustic piano's own resonance remains.
The sound of the higher notes suddenly changes from a certain key	On an acoustic piano, the higher notes of the piano (from the highest key down around 1½ octaves) fully sustain after you play them even if the damper pedal is not pressed. The sound is also different. In this way, this piano faithfully recreates the sound of an acoustic piano. Also, the key range that is unaffected by the damper pedal changes depending on the transpose settings.
When you press a key, the sound of a note you didn't press is also faintly heard	In some cases, a note you play might cause a different note (whose frequency is an integer multiple of the first note) to resonate, producing the sensation that the sound has changed; this is not a malfunction.
High-pitched ringing is heard	If you can hear this in headphones: Some piano tones that feature a brilliant and consistent sound include many high-frequency components, which may include some reverberations that could sound metallic. This is a faithful recreation of the original characteristics of a piano, and is not a malfunction. This kind of reverberation tends to be more audible when the more ambience effect is applied, so you might try reducing the ambience effect to help mitigate this issue.
	If you can't hear this through headphones: There may be another issue causing this, such as the sound resonating with the piano unit. Please contact your dealer or a Roland customer service center.
Low notes sound wrong, or are buzzy	Could the volume be set to maximum?	If the volume is at the maximum, the sound might be distorted depending on how you play the piano. If this occurs, lower the volume.
	If you can hear this in headphones: It may be that the piano has malfunctioned. Please contact your dealer or a Roland customer service center.
	If you can't hear this through headphones: It may be that the objects near the piano are resonating because of the high volume of sound coming from the speakers. You can take the following measures to minimize resonances. Keep the volume down. Locate the speakers 10–15 cm (4–6 inch) away from walls or other surfaces. Move away from the objects that are resonating.
The sound is heard differently depending on the tone settings	When using "Dual Play" which layers two tones, the sound you hear may differ depending on the specific combination. For some combinations, the effect is not applied to the left-hand tone. This is not a malfunction.
Problems with the pedals
Unusual sound is heard when you press the pedal	Could the adjuster located under the pedal not be in contact with the floor?	The adjuster may have loosened as you used the pedal. Lower the adjuster so that it contacts the floor. If you are using the piano on carpet, lower the adjuster so that it presses strongly against the floor.
Pedal does not work, or is "stuck"	Is the pedal connected correctly?	Check the pedal jack located on the bottom of the piano.
	Could you have disconnected or connected the pedal cord while the power was on?	If you disconnect the pedal cord while the piano is powered-on, the pedal effect might remain applied. Connect or disconnect the pedal cord while the piano is powered off.
	Could Twin Piano be turned on?	If Twin Piano is on, the right pedal will affect only the right-hand keyboard zone and the left pedal will affect only the left-hand keyboard zone.
Problems with song playback
Song volume is inaudible or too low	Is the song playback volume set to "1"?	Raise the song playback volume.
Changing the "Song Volume" does not change the volume.	Could the SMF Play Mode be set to "Internal"?	Set the SMF Play Mode to "External".
The selected sound changes when you play back a song	Could the SMF Play Mode be set to "Internal"?	Set the SMF Play Mode to "External".
Can't play back a song saved in USB flash drive	Is the file extension ".WAV" or ".MP3" or ".MID"?	This piano can play back three types of file: WAVE format or MP3 format audio files, and MIDI files.
Problems with recording
Volume differs between recording and playback	Is the song playback volume set too low?	Raise the song playback volume.
Other problems
Can't change the settings	Is the topmost volume indicator blinking rapidly?	If the topmost volume indicator is blinking rapidly, the piano is in record standby mode, or is currently recording. In this state, only these functions are available: adjusting the volume, starting and stopping the metronome, changing the metronome's volume and changing the tempo.
Even though you're using headphones to mute the sound, a thumping sound is heard when you play the keyboard	The keyboard of this piano is designed to simulate the mechanism of an acoustic piano. Even on an acoustic piano, a thumping sound is actually being produced when you press a key. Such sounds do not indicate a malfunction.
Power turns off on its own	Could you have made settings so that the power automatically turns off when the piano has not been used for a time?	If you don't need the power to turn off automatically, turn the Auto Off setting "Off".
	When trying to play an SMF or audio file recorded at an extremely loud volume from a USB flash drive, the protective circuit of this unit may activate and shut off the power.	Lower the song playback volume.
Power does not turn on	Is the AC adaptor connected correctly?
Even-numbered or oddnumbered volume indicators are alternately blinking	A system error has occurred. Turn the piano off and on again. If this doesn't solve the problem, perform a factory reset.
Can't use Roland Cloud	Please be aware that in some countries or regions, it might not be possible to use Roland Cloud at this time.

ALWAYS OBSERVE THE FOLLOWING

Concerning the Auto Off function

The power to this unit will be turned off automatically after a predetermined amount of time has passed since it was last used for playing music, or its buttons or controls were operated (Auto Off function). If you do not want the power to be turned off automatically, disengage the Auto Off function.

Use only the supplied AC adaptor and the correct voltage

Be sure to use only the AC adaptor supplied with the unit. Also, make sure the line voltage at the installation matches the input voltage specified on the AC adaptor's body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.

Use only the supplied power cord

Use only the attached power cord. Also, the supplied power cord must not be used with any other device.

Use due care when handling the lid

• The lid should be opened and closed only by an adult.
• The lid must not be opened too far (we recommend that you do not open it by more than about 30 degrees). If opened to an extreme degree, you risk damaging the piano or having the lid fall unexpectedly. Also, when opening the lid, make sure that no one is in the way.

IMPORTANT NOTES

Power Supply

• Place the AC adaptor so the side with the indicator faces upwards. The indicator will light when you plug the AC adaptor into an AC outlet.

Placement

• 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.
• 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.

Care of the Keyboard

• Do not write on the keyboard with any pen or other implement, and do not stamp or place any marking on the instrument. Ink will seep into the surface lines and become unremovable.
• Do not affix stickers on the keyboard. You may be unable to remove stickers that use strong adhesives, and the adhesive may cause discoloration.
• To remove stubborn dirt, use a commercially available keyboard cleaner that does not contain abrasives. Start by wiping lightly. If the dirt does not come off, wipe using gradually increasing amounts of pressure while taking care not to scratch the keys.

Concerning the Care of the Unit (Mirror Finish)

• The surface of this unit has been polished so as to create a high-gloss, mirror-like finish. Since this beautiful finish is as delicate as that of the highest quality, wood-crafted furniture, it needs to be cared for at regular intervals. Please make sure to observe the following when caring for the unit.
• For routine care, gently clean the surface using a soft cloth or a piano-use feather duster. You must avoid applying any force, since even the tiniest particles of sand or grit can produce scratches if you wipe too hard.
• If the finish loses its luster, use a soft cloth dampened with some polishing liquid to evenly wipe the surface of the unit.
• Avoid using detergents or other cleaners, as they can cause the surface finish to deteriorate. This may lead to the formation of cracks or other imperfections. Also, do not use chemically-enhanced cleaning cloths.
• Precautions concerning the use of polishing agents
• Refer to the instructions that came with the polishing agent for instructions on its proper use.
• Use only polishing agents that are designed specifically for use on the mirror finishes of pianos. By using any other product, you risk causing scratches, deformation, discoloration, etc. To purchase an appropriate product, please consult the nearest musical instrument store.
• Use the product only on the portions of this unit that have a mirror-like finish, and using an even touch, apply it equally over the entire surface. If you apply more force in one place over another, you risk losing some of the luster of the finish.
• Store in a location that is out of the reach of small children. If accidentally ingested, induce vomiting immediately. Then, see a doctor to obtain a diagnosis.
