Customizing the V-Piano’s sounds
Unison Tune
Range: -100–+100
Normally, there are three strings for each key of a piano (lower
notes have one or two strings). A beautiful resonance can be
created by slightly detuning the pitch of these strings.
Adjusting this parameter to a higher positive (+) value will
increase the pitch differences between the 2nd string and the 1st
and 3rd strings.
When this value is 0, the three strings will be detuned as they are
on a typically tuned piano.
Adjusting this parameter to a lower negative (-) value will decrease
the pitch differences between the 2nd string and the 1st and 3rd
strings. With the setting of -100, the pitch differences between the
three strings will be minimum.
For keys that have only one string, adjusting this
parameter will have no effect.
Stretch Tune
Most pianos are tuned so that the lower range is flatter and the upper range is sharper than the theoretically calculated pitches of
equal temperament. This makes chords sound more beautiful. This method of tuning is distinctive to pianos, and is called “Stretch
Tuning.”
For details, refer to “Editing the stretch tune” (p. 54).

Hammer Hardness
Range: -100–+100
This adjusts the hardness of the hammer felt.
Increasing this value will make the felt harder, producing a bolder
sound.
Decreasing this value will make the felt softer, producing a softer
tone.
Cross Resonance
Range: -100–+100
This adjusts the proportion of the various parasitic vibrations that
occour along with the basic vibration of the strings, which
produces the basic sound of the piano.
Increasing this value will increase the proportion of the parasitic vibration.
For the strings of the low notes in particular, this will increase the metallic resonance of the high-frequency range.
Lowering this value will decrease the proportion of the parasitic vibration.
Decay Time
Range: -100–+100
This adjusts the time over which the volume decays after reaching its peak.
Increasing this value will lengthen the time over which the volume decays; reducing this value will shorten the time.
