Playing Various Musical Instrument Sounds (Voices) 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, with each influencing the rest, 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 Aliquot? Aliquot 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. 26 YDP-184 Owner's Manual

Playing Various Musical Instrument Sounds (Voices)
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, with each influencing the rest, 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 Aliquot?
Aliquot 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.
