Playing Various Musical Instrument Sounds (Voices) Item Grand Expression Icon Descriptions 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." Default settings Dynamic Setting range Dynamic, Static Half Pedal Point Listening to the Demo 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." Specify the point to which you must depress the pedal before 0 the effect of "Sustain (Continuous)" begins to be applied. This setting applies only to the "Sustain (Continuous)" effect (page 17) that is assigned to the right pedal connected to the [PEDAL UNIT] jack or the foot pedal/footswitch connected to the [AUX PEDAL] jack. -2 (effective with the shallowest press) - 0 - +4 (effective with the deepest press) 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 90. • The items listed above can also be set in the "Voice" menu (page 95) or the "System" menu (page 103). 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 the [-] and [3] buttons simultaneously while the setting value is shown. Glossary of terms Term Damper Noise Duplex Scale Grand Expression Modeling VRM (Virtual Resonance Modeling) Description 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. 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 the dampers do not touch them, they will continue sounding even after you release your hands from the keyboard. 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. 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. 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. 25 P-525 Owner's Manual
