Open strings

When keys are struck with the damper pedal pressed, their strings resonate along with other strings with vibration

frequencies close to their harmonic overtone components, and the open treble strings resonate with them as well.

Damper Resonance

String Resonance

When the G, C and E keys are struck (chord), the strings associated with these keys resonate with each other, and the open treble

strings resonate along with them

When the C key is struck (single tone), the C string and the open treble strings resonate with each other

88-Key Stereo Resonance Simulator

Reproduces Deep Acoustics

String and Damper Resonance

for Authentic Acoustics

When the C key is struck (single tone), the C string and the open treble strings resonate with each other.

When the G, C and E keys are struck (as a chord), the strings associated with these keys resonate with each

other, and the open treble strings resonate along with them.

When keys are struck with the damper pedal pressed, their strings resonate along with other strings with

vibration frequencies close to their harmonic overtone components, and the open treble strings resonate with

them as well.

system

achieving deep, rich resonance

with 88 keys

The uniquely rich sound produced

by an acoustic piano is a combination

of the sound generated by the striking

of keys and the associated string

resonance created by that original

key strike.

The Multi-Dimensional Morphing AiR

Sound Source, unlike ordinary digital

pianos, adopts a string resonance

system incorporating a stereo

resonance simulator for all 88 keys –

meaning that the resonance of all 88

keys is reproduced completely and

naturally. Furthermore, the resonance

created by playing a single tone,

according to the strength of touch,

is differentiated from that of playing a

chord. The result is authentic, natural,

acoustic-piano resonance.

Damper Resonance

achieving

a more naturally beautiful

resonance than a pedal

The deep, beautiful resonance resulting

from the use of a damper pedal is

also reproduced naturally by a stereo

resonance simulator installed on all

88 keys, an approach that differs from

conventional simulated reproduction-

effect processing. The attention to

detail goes so far as to simulate the

resonance created by the lifting of the

dampers themselves when the pedal

is pressed.

A continuously variable system

has

been adopted for the damper pedal,

meaning accurate reproduction of even

subtle changes in reverberation caused

by the delicate pressure exerted by

partial pedal operation. This enables

players to authentically employ pedal

operation to achieve graceful and

expressive performances.
