Customizing the V-Piano’s sounds

 

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.

 

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.”

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.

 

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.

 

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.
