NU1X Owner’s Manual •21
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 Mod-
eling) technology featured in the NU1X reproduces the complicated interaction of both string and sound-
board 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 press-
ing the keys, and the timing and depth of your pressing the pedal.
The default setting of this function is on. Simply by selecting a VRM Voice (page 17), you can enjoy the
VRM effect. You can turn the VRM function on or off, and adjust the depth.
Turning the VRM function on or off
While holding down [PIANO/VOICE], press the C0 key repeatedly (if necessary).
Adjusting the depth of the VRM effect
While holding down [PIANO/VOICE], press one of the keys in the ranges of D0–D1.
During the operation, the specified value is shown on the display.

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 com-
plex color to the sound. Since they do not have damper, they will continue sounding
even after you release your hands from the keyboard.
