You can hear and experience the characteristics of the Voices by listening to the Demo Songs for each Voice (page 28).

Selecting Other Piano Voices
Press the [Cursor left]/[Cursor right] buttons to select other piano Voices than “CFX Grand” and “Bösendorfer.” You can also select the other Voices by pressing the [VOICE] button (page 26).


Customizing the Sound and the Touch Sensitivity of Piano Voices (Piano Room)
You can adjust the detailed settings of Voices in the Piano group in the Piano Room. Try creating a custom piano sound by adjusting the various parameters such as lid position, string resonance, damper resonance and so on.

Parameters you can set in the Piano Room
(Table)
Item		Icon	Description	Default setting	Setting Range
Lid Position	(Figure)		Recreates the differences in sound depending on how high the (virtual) grand piano lid is opened.	Full	Full, Half, Closed
Brightness	(Figure)		Adjusts the brilliance of sound.	Differs depending on the Voice.	0 – 10
Touch		(Figure)	Determines how the sound responds to your playing strength. You should adjust this setting according to the specific Voice you’re playing or the particular Song you’re performing, as desired.	Medium	Soft2, Soft1, Medium, Hard1, Hard2, Fixed
Reverb		(Figure)	Determines the Reverb type which is applied to all the entire sound including the keyboard performance, Song playback and MIDI data input from an external MIDI device.	Differs depending on the Voice.	Refer to the Reverb Type List (page 29)
	Reverb Depth	(Figure)	Adjusts the Reverb depth. When “Reverb” is set to “off” or a value of “0,” no effect is produced.	Differs depending on the Voice.	0 – 40
Master Tune	(Figure)		Fine tunes the pitch of the entire instrument. This function is useful when you play this instrument along with other instruments or CD music.	A3 = 440.0 Hz	A3 = 414.8 Hz – 466.8 Hz (approx. 0.2 Hz steps)
VRM		(Figure)	Turns the VRM effect on/off. For information about the VRM function, refer to page 25.
Listening to the VRM Demo 
(Figure)
Press the [PLAY/PAUSE] button while this display is open to play back the VRM Demo Song. You can hear the Demo Song with and without the effect (VRM on or off). 
The five parameters below can be set when “VRM” is On. 	On	On, Off
	Damper Resonance	(Figure)	Determines the depth of the string resonance effect which is applied when the damper pedal is pressed. 	5	0 – 10
	Damper Noise		Turns the Damper Noise produced by the VRM function On/Off. For details on damper noise, refer to page 25. This function will be disabled when “Damper Resonance” is set to “0.”	On	On, Off
	String Resonance	(Figure)	Determines the depth of the string resonance effect which is applied when a note on the keyboard is pressed. 	5	0 – 10
	Duplex Scale Resonance		Adjusts the sympathetic vibrations of the duplex scaling resonance effect in VRM. For details about duplex scaling, refer to “What is Duplex Scale?” (page 25).	5	0 – 10
	Body Resonance		Adjusts the resonance of the piano itself (the soundboard, the sides, the frame and so on) in VRM.	5	0 – 10
Grand Expression		(Figure)	Selects the type of the Grand Expression Modeling effects, which simulates the physical sound transitions of an actual piano. When this feature is set to “Dynamic,” you can control extremely subtle nuances in the performance and sound by changing your playing strength or touch. When set to “Static,” the nuances are generally fixed. For details about Grand Expression Modeling, refer to the below.
NOTE
Grand Expression Modeling is effective only for the Voices of “CFX Grand” and “Bösendorfer.”
Listening to the Demo 
(Figure)
Press the [PLAY/PAUSE] button while this display is open to play back the Demo Song of this function. You can listen to the Demo song with “Dynamic” or “Static.”	Dynamic	Dynamic, Static
Half Pedal Point		(Figure)	Specify the point to which you must depress the right pedal before the effect of “Sustain Continuously” begins to be applied. This setting applies only to the “Sustain Continuously” effect (page 80) that is assigned to the right pedal.	0	−2 (effective with the shallowest press) – 0 – +4 (effective with the deepest press)
(Table end)

NOTE
• If you wish to keep the Piano Room settings even after turning off the power, set “Voice” and “Other” in the “Backup” setting to “On.” For details, refer to page 92.
• The items listed above can also be set in the “Voice” menu (page 77) or the “System” menu (page 85). When you change these settings in the Piano Room display, the settings in the menu displays will also be changed. Conversely, changing the settings in the menu displays will also change the settings in the Piano Room display.
• To restore the default value, press and hold the Menu button while the setting value is shown.


What is VRM?
The VRM (Virtual Resonance Modeling) function uses sophisticated physical modeling to simulate the actual string resonance sound that occurs when the damper pedal on a real piano is pressed or keys are played and held.
On an actual acoustic piano, if you press the damper pedal and play a key, not only does the string of the pressed key vibrate, it also causes other strings and the soundboard to vibrate, each influencing the rest and creating a rich and brilliant resonance that sustains and spreads. The VRM (Virtual Resonance Modeling) technology featured in this instrument reproduces the complicated interaction of both string and soundboard resonance faithfully using a virtual musical instrument (physical modeling), and makes the sound more like a real acoustic piano. Since instantaneous resonance is made at the moment according to the state of the keyboard or pedal, you can vary the sound expressively by changing the timing of your pressing the keys, and the timing and depth of your pressing the pedal.

What is Duplex Scale?
Duplex scaling is a stringing method for pianos that uses extra, un-struck strings in the upper octaves to enhance the tone. These strings sympathetically vibrate with other strings in an acoustic piano, resonating with overtones, and adding richness, brilliance and complex color to the sound. Since they do not have a damper, they will continue sounding even after you release your hands from the keyboard.

What is Damper Noise?
Damper noise is the sound made on an acoustic piano when the damper pedal is pressed. The damper noise changes in tone and volume depending on how quickly the damper pedal is pressed down. Pressing the damper pedal slowly will make a quieter sound when the damper heads are released from the strings. Pressing the damper pedal with force will transmit the vibrations to the strings, which adds a lower and louder sound.


What is Grand Expression Modeling?
On an actual acoustic piano, subtle changes in the sound can be produced by changing your playing touch from when you press a key to when you release it. For example, when you press a key all the way to its bottom, the key hits the keybed underneath and the noise reaches the strings, changing the sound slightly. Furthermore, the tone when the damper is lowered onto strings to mute the sound is changed by how quickly you release the key. The Grand Expression Modeling technology recreates these subtle changes in the sound that respond to your touch. This allows you to add accents by playing strongly or add resonance by playing softly to produce superbly expressive sound. A crisp tone can be heard when playing staccato as well as a lingering sound produced when releasing the keys slowly.
