n experienced piano technician is essential to fully realise the potential of a ê ne acoustic piano. In addition to
meticulously tuning each note, the technician also performs numerous regulation and voicing adjustments that
allow the instrument to truly sing.
The VPA (Virtual Piano Artisan) settings of the digital piano simulate these re
ê nements digitally, allowing
performers to shape various aspects of the instrument’s character to suit their personal preferences.
VPA Detailed Settings
When a non-piano sound is selected, the “VPA” AA area will be replaced by an “Other sound settings” area,
which contains similar adjustable settings.

Item Description Operation
To TT uch Curve
As with an acoustic piano, the digital piano produces a louder sound
when the keys are struck with force, and a soft ff er sound when the keys
are played gently. The volume and tonal character change in relation to
the strength and velocity of playing on the keyboard is referred to as a
“touch curve”.
Voicing
The To T uch Curve setting allows the touch sensitivity of the keyboard to
be conveniently adjusted. There are ten di é erent preset touch curve
settings available. On an acoustic piano, the shape, density, and texture
of the hammers all in ë uence the tonal character of the instrument’s
sound. Te TT chnicians utilise a variety of tools such as needles, ê les, and
brushes to manipulate these hammer felts, with the ultimate goal of
achieving a balanced tonal character across the keyboard. The Voicing
setting recreates various hammer properties, allowing the overall tonal
character of the digital piano to be adjusted.
Resonance Rendering
On an acoustic piano, the strings vibrate when the keyboard is played or
the pedals are depressed, creating a rich resonance. In addition, the
resonance sound changes in a complicated manner according to the
keyboard touch and the state of the pedals. The Resonance Rendering
setting allows the overall resonance e é ect of the SK-EX Rendering sound
engine to be adjusted.
Damper Noise
When the damper pedal of an acoustic piano is pressed and released, it
is oft ff en possible to hear the sound of the damper head touching and
releasing the strings. The digital piano reproduces this sound, with the
Damper Noise setting allowing the volume of this sound to be adjusted.
The speed at which the damper pedal is pressed and released will also
in ë uence the prominence of the damper noise, with fast pedalling
creating a more pronounced sound.
Undamped String Resonance
The dampers of an acoustic piano span almost the full width of the
keyboard. However,rr the topmost 18 keys (approximately 1.5 octaves) do
not incorporate dampers, as the shorter strings for these treble notes
decay quickly and therefore do not need to be dampened. As a result,
the strings of these “undamped” treble notes are free to vibrate in
sympathetic resonance with those of lower keys independently of the
damper pedal position – helping to enrich the sound with additional
harmonics and tonal colour.rr The digital piano recreates this
phenomenon, with the Undamped String Resonance setting allowing
the volume of this resonance sound to be adjusted.
