NOTE
• Of the digital piano's 18 built-in tones, the first five are grand piano tone. Each tone has its own distinctive merits, so you should select the tone that suits the song you are playing along with or your own personal preferences. The CONCERT and MODERN tones are assigned to buttons for quick and easy selection.
Tone Name | Characteristics |
CONCERT | This is a full concert grand piano tone that uses Linear Morphing* for dynamic and natural tone changes. This tone is designed to reproduce damper, resonance, and other piano nuances, which makes it ideal for virtually any type of piano performance. |
MODERN | This tone provides a bright grand piano sound. The volume and timbre of this tone is quick to respond to different keyboard pressures, and it has relatively strong reverb. This tone is a good choice for dynamic and lively performances. |
CLASSIC | This is a natural piano tone that closely resembles the sound of an acoustic piano. Though reverb and other flashy effects are subdued for this tone, resonance is more pronounced, which enables expression of delicate nuances. This tone is a good choice for lesson and practice sessions. |
MELLOW | Warm and mellow piano tone |
BRIGHT | Bright and clear piano tone |
* Feature that applies computer morphing technology to enable seamless changes between sounds sampled at various dynamics from a full concert grand piano.
Bass Tones (BASS 1, BASS 2)
Selecting either of the two BASS (LOWER) tones (1 or in step 1 of the above procedure will assign the selected bass tone to the low range (left side) of the keyboard. The high range (right side) will be assigned the tone that was selected when you pressed the BASS 1 or BASS 2 key.
• BASS 1 and BASS 2 let you effectively split the keyboard between two different tones.
NOTE
• To return the keyboard to a single tone, select any tone other than BASS 1 or BASS 2.
• You cannot select BASS 1 or BASS 2 when recording to Track 2.
Adjusting Acoustic Piano Sound Characteristics
The tones of your digital piano have built-in elements that give them the characteristic reverberation of an acoustic piano. Each of these elements can be individually adjusted to one of four levels.
- HAMMER RESPONSE
Controls the time deviation between when a key is pressed and when the note actually sounds.Settings
1: Fast 2: Grand piano feel 3: Slightly slower 4: Slow - STRING RESONANCE
Adjusts the characteristic reverberation (string resonance) of an acoustic piano.
You can select a reverberation setting that matches the song being played or your own personal preference.Settings
1: Suppressed 2: Slightly suppressed
3: Reverberation 4: Strong reverberation - LID SIMULATOR
Adjusts how sound resonates in accordance with the opening state of a grand piano lid.Settings
1: Lid closed 2: Lid opened slightly 3: Lid fully open 4: Lid removedNOTE
• Opening or closing the digital piano’s lid does not affect the LID SIMULATOR setting.- While holding down the FUNCTION button, press the button that corresponds to the element whose setting you want to change.
- Each press of the button cy cles to the next option for that setting. The digital piano emits a beep pattern that indicates the currently selected option:
One beep: Option 1 → Two beeps: Option 2 → Three beeps: Option 3 → Four beeps: Option 4 → One beep: Option 1, etc. - The lamp of each button lights whenever the standard setting of its element is selected.
NOTE
• In addition to the above, piano tones also have a KEY OFF SIMULATOR. - KEY OFF SIMULATOR
Causes notes to decay when keyboard keys are released.
Layering Two Tones
Use the following procedure to layer two tones, so they sound at the same time.
When specifying two tones for layering, first tone you select will be the main tone, while the second tone will be the layered tone.

Example: First press the HARPSICHORD key and then the STRINGS 1 key. - To unlayer the keyboard, select another tone by pressing the GRAND PIANO button or by using the procedure under “Selecting and Playing a Tone” (page E-5).
NOTE
• You cannot layer the BASS 1 or BASS 2 tone with another tone.
• You cannot perform the layer operation when recording to Track 2.
To adjust the volume balance between two layered tones
- While holding down the FUNCTION button, use the keyboard keys shown below to adjust the volume of the layered tones.
• To return the volume setting to its initial default, hold down the FUNCTION button and press both of the keys at the same time.

■ About DSP
DSP makes it possible to digitally produce complex acoustic effects. The DSP is assigned to each tone whenever you turn on digital piano power.
Using the Digital Piano’s Pedals
Your digital piano comes equipped with three pedals: damper, soft, and sostenuto
Pedal Functions
-
Damper Pedal
Pressing the damper pedal while playing will cause the notes you play to reverberate for a long time.
• When a GRAND PIANO tone (CONCERT, MODERN, CLASSIC, MELLOW, BRIGHT) is selected as the tone, pressing this pedal will cause notes to reverberate (with damper resonance) just like the damper pedal on an acoustic grand piano. Half-pedal operation (pressing the pedal part way) is also supported. -
Soft Pedal
Pressing this pedal while playing suppresses notes played on the keyboard after the pedal was pressed, and makes them sound softer. -
Sostenuto Pedal
Only the notes of the keys that are depressed when this pedal is pressed are sustained until the pedal is released.
Using the Metronome
-
Press the METRONOME button.
• This starts the metronome.
• The lamp above the SONG button flash in time with the metronome beat. -
To change the beat, hold down the FUNCTION button as you press one of the METRONOME BEAT keys to select a beat setting.
• You can specify beats per measure value of 0, 2, 3, 4, 5, or 6. Specifying 0 as the setting plays a straight click, without any chime. This setting lets you practice with a steady beat. -
While holding down the FUNCTION button, use the TEMPO keys to specify a tempo value in the range of 20 to 255 beats per minute.
• Each press of the + or – key raises or lowers the tempo value by 1.
• You can use the value input keys (0 to 9) to enter a specific three-digit. Be sure to input all three digits.
Example: To enter “96”, press keys 0, 9, 6. -
Press the METRONOME button or SONG button to turn off the metronome.
NOTE
To return the tempo setting to the default tempo of the currently selected Music Library tune, press the + and – keys at the same ti me in step 3. Pressing + and – while recording will return the tempo value to 120.
To adjust the metronome volume
You can perform the following procedure at any time, regardless of whether or not the metronome is sounding.
- While holding down the FUNCTION button, use the METRONOME VOLUME keys to specify a volume value in the range of 0 to 42.
• For details about using the keyboard keys for settings, see “Keyboard Keys Used for Configuring Settings” on page E-22.
• Each press of the or key raises or lowers the metronome volume value by 1.
NOTE
• To return to the initial default setting, press and at the same time.
Playing a Piano Duet
You can use the Duet Mode to split the piano’s keyboard in the center so two people can play a duet.
Keyboard
The left and right side keyboards have virtually the same range. The left pedal operates as the left side damper pedal, while the right pedal is the right side damper pedal.
Pedals
The Duet Mode is the perfect way to conduct lessons, with the teacher playing on the left side as the student playing the same song on the right side.
NOTE
• Only the damper pedal for the right side keyboard supports half-pedal operations.
-
Select the piano tone you want to use for the duet.
Example: GRAND PIANO (MODERN) -
While holding down the FUNCTION button, press the METRONOME button to toggle duet on (lamp lit) and off (lamp unlit).
IMPORTANT!
• You cannot use the Duet Mode while recording (page E-15).
Changing the Oc taves of the duet keyboards
You can change the ranges of the left and right keyboards in octave units from their initial default settings. This comes in handy, for example, if the initial default range is not enough when one person is playing the left hand part and another person is playing the right hand part.
-
While holding down the FUNCTION and METRONOME buttons, press the keyboard C key that you want located at C4 (middle C) of the left keyboard.
• This will sound the note as signed to C4 and change the octave of the left keyboard.
Example: Press the keyboard key of the leftmost C (C4) will assign the range shown below. -
While holding down the FUNCTION and METRONOME buttons, press the keyboard C key that you want located at C4 (middle C) of the right keyboard.
• This will sound the note as signed to C4 and change the octave of the right keyboard.
NOTE
• You can return the keyboards to their initial default ranges by exiting and then re-entering the Duet Mode.
