Cabinet Resonance
While the fundamental sound of an acoustic piano is produced by vibrating
strings, transmitting energy through a spruce soundboard, the cabinet of the
instrument itself also contributes a variety of subtle tonal characteristics that
enrich the playing and listening experience. The digital piano recreates these
natural acoustic characteristics, with the Cabinet Resonance setting allowing the
volume of this resonance sound to be adjusted.
Key-o é E é ect
When playing an acoustic piano – particularly in the bass region of the keyboard –
if a key is played with force and released quickly, it is oft ff en possible to hear the
faint sound of the damper touching the strings immediately before the vibrations
are stopped. The digital piano recreates this phenomenon, with the Key-o é E é ect
setting allowing the volume of this sound to be adjusted.
Fall-Back Noise
When playing an acoustic piano, it is oft ff en possible to hear the faint sound of the
keyboard action returning (i.e., “falling back”) to the neutral position aft ff er a key is
released. The digital piano reproduces this sound, with the Fall-back Noise setting
allowing the volume of this sound to be adjusted.
Hammer Noise
When playing an acoustic piano, it is also possible to hear the physical sound of
the hammers striking the strings, along with the sound of the keys making
contacting with the piano keybed. The digital piano reproduces this sound, with
the Hammer Noise setting allowing the volume of this sound to be adjusted.
Hammer Delay
When playing pianissimo passages using an acoustic piano, there may be a
perceived delay between a key being pressed and the hammer striking the strings.
The digital piano recreates this delay, with the Hammer Delay setting allowing the
delay length to be adjusted.
To TT pboard
When playing an acoustic grand piano, the position of the instrument’s topboard
(lid) a é ects both the volume and “openness” of the tone produced. The digital
piano simulates these characteristics, with ê ve di é erent topboard positions.
Decay Time
In a grand piano, the length of the decay time of the sound aft ff er playing the
keyboard di é ers depending on the length of the strings. The digital piano
reproduces this characteristic, with the Decay Time setting allowing the length of
decay while keys are pressed to be adjusted.
Release Time
With a grand piano, the length of time at which the sound decays aft ff er the
keyboard is released di é ers depending on the size of the instrument. The digital
piano reproduces this characteristic, with the Release Time setting allowing the
length decay aft ff er keys are released to be adjusted.
Minimum To TT uch
With an accoustic piano, there is a range in which an extremely ê ne touch on the
keyboard does not produce sound. The digital piano reproduces this characteristic,
with the Minimum To TT uch setting allowing the minimum key velocity required to
produce a sound to be adjusted.
Stretch Tuning
Stretch tuning is a piano-speci ê c tuning method used by acoustic piano
technicians in which the lower octaves are tuned slightly ë atter and the upper
octaves are tuned slightly sharper to match the natural harmonics of an acoustic
piano. The Stretch Tuning setting allows the degree of stretch tuning to be
adjusted with three types of stretch tuning, or for stretch tuning to be completely
disabled. It is also possible to create custom tuning methods by adjusting the pitch
of each individual key.
