Description
Determines whether the Quiet mode (Qt) is enabled or
the Acoustic mode (Aco) is enabled when the power is
turned on.
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.
