Virtual Technician

An experienced piano technician is essential to fully realise the potential of a fine 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 Virtual Technician settings of the digital piano simulate these refinements digitally, allowing performers to shape various aspects of the instrument’s character to suit their personal preferences.

CHECK

When a non-piano sound is selected, the “Virtual Technician” area will be replaced by an “Other sound settings” area, which contains similar adjustable settings.

Entering the Virtual Technician

From the Piano window, tap the Selection bar to open the Piano Editor window, then tap [EDIT] button in the Virtual Technician area.

CHECK

The number of adjustable Virtual Technician parameters will vary depending on the selected sound.

① Touch Curve

As with an acoustic piano, the digital piano produces a louder sound when the keys are struck with force, and a softer sound when the keys are played gently. The volume and tonal character change in relation to the strength and velocity of playing – on a digital piano this system is referred to as “touch sensitivity”.

The Touch Curve setting allows the touch sensitivity of the keyboard to be conveniently adjusted. There are ten different preset touch curve settings available, and an additional “User” settings that allows performers to create their own personalised touch curve.

The default “Normal” setting is designed to accurately recreate the touch of a Kawai concert grand piano. However, if the keyboard feels too light, or fortissimo playing is achieved too easily, it may be desirable to select a heavier touch curve. Alternatively, if the keyboard feels too heavy, or fortissimo playing is too difficult to achieve, it may be desirable to select a lighter touch curve.

Type	Description
Light (4/3/2/1)	Light touch curves require less striking force to achieve a forte note, and are therefore recommended for players with a delicate touch. The key touch will become progressively lighter as the number increases.
Normal	Reproduces the standard touch sensitivity of an acoustic piano.
Heavy (1/2/3/4)	Heavy touch curves require more striking force in order to achieve a forte, and are therefore recommended for players with stronger fingers. The key touch will become progressively heavier as the number increases.
Off (constant)	A constant volume is produced regardless of how hard the keys are struck.This touch curve intended for playing sounds of instruments that have a fixed dynamic range (e.g. organ and harpsichord).
User	A custom touch curve, created by moving individual points along the curve.

Touch Curve Editor

The Touch Curve Editor allows the User Touch Curve type to be edited.
Select the [User] Touch Curve type, then tap the [EDIT] button to display the Touch Curve Editor screen.

＋

To edit the User Touch Curve, swipe over that area of the screen to "draw" the curve.
For more precise editing, it is also possible to select one of the eight dynamics levels, then increase or decrease the velocity level.
To reset the User Touch Curve to the default (linear) values, tap the [RESET] button.

② Voicing

On an acoustic piano, the shape, density, and texture of the hammers all influence on the tonal character of the instrument’s sound. Technicians utilise a variety of tools such as needles, files, 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. There are six different preset voicing settings available (applied uniformly to all keys), with an additional “User” setting allowing players to perform custom adjustments on each individual key.

While the default “Normal” voicing setting should be appropriate for a broad range of musical genres, it may be desirable to select a softer, more mellow tonal character for romantic pieces, or a brighter, more aggressive tone for modern styles.

Type	Description
Normal	The normal tonal character of an acoustic piano throughout the entire dynamic range.
Mellow 1	A softer, more mellow tonal character throughout the entire dynamic range.
Mellow 2	An even softer tonal character than Mellow 1.
Dynamic	A tonal character that changes dramatically from mellow to bright, depending on the strength of key strike.
Bright 1	A bright tonal character throughout the entire dynamic range.
Bright 2	An even brighter tonal character than Bright 1.
User	A custom tonal character, allowing each key to be individually voiced.

User Voicing

The User Voicing function allows each of the 88 keys to be voiced individually.
Select the [User] Voicing type, then tap the [EDIT] button to display the Voicing Editor screen.

The Voicing value can be adjusted within the range of –5~+5, with negative values creating a mellower sound and positive values creating a brighter sound.
To reset the User Voicing setting to the default values, tap the [RESET] button.

③ Resonance Depth

The Resonance Depth setting allows the overall resonance depth of the SK-EX Rendering sound engine to be adjusted.

Value	Description
1	A small amount of Resonance will be applied to the selected SK-EX Rendering sound type.
～	～
10	A large amount of Resonance will be applied to the selected SK-EX Rendering sound type.

CHECK

This setting will only be displayed when the “SK-EX Rendering” piano sound variation is selected.

④ Damper Resonance

Pressing the damper pedal of an acoustic piano raises all dampers, allowing the strings to vibrate freely. When a note or chord is played on the piano with the sustain pedal pressed, not only will the strings of the notes played vibrate, but also the strings of other notes, vibrating in sympathetic resonance. The digital piano recreates this phenomenon, with the Damper Resonance setting allowing the volume of this resonance sound to be adjusted.

Value	Description
Off	Damper Resonance will not be applied to the selected sound.
1	A small amount of Damper Resonance will be applied to the selected sound.
～	～
10	A large amount of Damper Resonance will be applied to the selected sound.

CHECK

This setting will not be displayed when the “SK-EX Rendering” piano sound variation is selected.

⑤ Damper Noise

When the damper pedal of an acoustic piano is pressed and released, it is often 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 influence the prominence of the damper noise, with fast pedalling creating a more pronounced sound.

Value	Description
Off	Damper Noise will not be applied to the selected sound.
1	A small amount of Damper Noise will be applied to the selected sound.
～	～
10	A large amount of Damper Noise will be applied to the selected sound.

⑥ String Resonance

String Resonance refers to a phenomenon that exists in acoustic pianos whereby the strings of held notes resonate “sympathetically” with other notes of the same harmonic overtone series. The digital piano recreates this phenomenon, with the String Resonance setting allowing the volume of this resonance to be adjusted.

Value	Description
Off	String Resonance will not be applied to the selected sound.
1	A small amount of String Resonance will be applied to the selected sound.
～	～
10	A large amount of String Resonance will be applied to the selected sound.

CHECK

This setting will not be displayed when the “SK-EX Rendering” piano sound variation is selected.

Demonstrating String Resonance

To experience the string resonance phenomenon, gently hold down the “C” key as shown in the illustration below, then play (strike and release quickly) any of the keys marked with a ● symbol. In addition to the sound of each note played, it should also be possible to hear the strings of the first “C” key resonating “sympathetically”, thus demonstrating String Resonance.

CHECK

The location and volume of the resonance may vary depending on the piano sound and settings used.

⑦ Undamped String Resonance

The dampers of an acoustic piano span almost the full width of the keyboard. However, 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. The digital piano recreates this phenomenon, with the Undamped String Resonance setting allowing the volume of this resonance sound to be adjusted.

Value	Description
Off	Undamped String Resonance will not be applied to the selected sound.
1	A small amount of Undamped String Resonance will be applied to the selected sound.
～	～
10	A large amount of Undamped String Resonance will be applied to the selected sound.

CHECK

This setting will not be displayed when the “SK-EX Rendering” piano sound variation is selected.

⑧ 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 keybed, inner and outer rim, iron plate, and beams all play a role in disseminating sound energy, which in turn gives the piano a living, breathing quality. The digital piano recreates these natural acoustic characteristics, with the Cabinet Resonance setting allowing the volume of this resonance sound to be adjusted.

Value	Description
Off	Cabinet Resonance will not be applied to the selected sound.
1	A small amount of Cabinet Resonance will be applied to the selected sound.
～	～
10	A large amount of Cabinet Resonance will be applied to the selected sound.

CHECK

This setting will not be displayed when the “SK-EX Rendering” piano sound variation is selected.

⑨ Key-off Effect

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 often 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-off Effect setting allowing the volume of this sound to be adjusted.

Value	Description
Off	Key-off Effect will not be applied to the selected sound.
1	A small amount of Key-off Effect will be applied to the selected sound.
～	～
10	A large amount of Key-off Effect will be applied to the selected sound.

⑩ Fall-Back Noise

When playing an acoustic piano, it is often possible to hear the faint sound of the keyboard action returning (i.e. “falling back”) to the neutral position after 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. While the default value is intended to simulate the natural volume level of the keys as they return to their neutral position, it may occasionally be desirable to adjust the volume of this sound. For example, reducing the volume when playing very soft pieces, where the fall-back noise may become too prominent.

Value	Description
Off	Fall-Back Noise will not be applied to the selected sound.
1	A small amount of Fall-Back Noise will be applied to the selected sound.
～	～
10	A large amount of Fall-Back Noise will be applied to the selected sound.

⑪ 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. While the default value is intended to simulate the natural volume level an acoustic piano, it may desirable to increase or decrease the volume of this sound to produce a more or less prominent attack.

Value	Description
Off	Hammer Noise will not be applied to the selected sound.
1	A small amount of Hammer Noise will be applied to the selected sound.
～	～
10	A large amount of Hammer Noise will be applied to the selected sound.

⑫ 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. If desired, the digital piano can recreate this delay, with the Hammer Delay setting allowing the delay length to be adjusted. While the default value of “Off” is intended to replicate a well-regulated concert grand piano, with an immediate connection between the keyboard and hammers, some players may find it desirable to introduce a minor delay, in order to mimic different types of piano or instruments with a slightly worn keyboard action.

Value	Description
Off	Hammer Delay will not be applied to the selected sound.
1	A small amount of Hammer Delay will be applied to the selected sound.
～	～
10	A large amount of Hammer Delay will be applied to the selected sound.

⑬ Topboard

When playing an acoustic grand piano, the position of the instrument’s topboard (lid) affects both the volume and “openness” of the tone produced. A fully open topboard allows sound waves to reflect off the polished lid surface and project into the room, while a closed lid has the opposite effect, resulting in a darker, more opaque tone. The digital piano simulates these characteristics, with five different topboard positions.

Type	Description
Open3	Simulates the character of a fully open topboard, with maximum sound projection.
Open2	Simulates the character of a half open topboard, with reduced sound projection.
Open1	Simulates the character of a partially open topboard, with limited sound projection.
Closed2	Simulates the character of a closed rear topboard, but open front topboard, with limited sound projection.
Closed1	Simulates the character of a closed rear topboard and closed front topboard, with minimum sound projection.

⑭ Decay Time

When playing an acoustic grand piano, the length of the instrument influences the speed at which held notes decay, with longer grand pianos (i.e. longer strings) characterised by longer decay times. The digital piano simulates this characteristic, with the Decay Time setting allowing the length of decay while keys are pressed to be adjusted.

Value	Description
1	Held notes will decay quickly.
～	～
10	Held notes will decay slowly.

⑮ Release Time

When playing an acoustic grand piano, the length of the instrument also influences the speed at which played (and released) notes decay, with longer grand pianos (i.e. longer strings) characterised by longer release times. The digital piano simulates this characteristic, with the Release Time setting allowing the length of decay after keys are released to be adjusted.

Value	Description
1	Released notes will decay quickly.
～	～
10	Released notes will decay slowly.

⑯ Minimum Touch

The Minimum Touch setting allows the minimum key velocity required to produce a sound to be adjusted. By default, this setting recreates the extremely fine touch sensitivity of a concert grand piano, allowing a very soft sound to be produced with the slightest of key touches. However, it may be desirable to reduce this sensitivity, when wishing to recreate the sensitivity of a small grand piano or an upright piano.

Value	Description
1	A very gentle key press will produce a very soft sound.
～	～
20	A stronger key press will be required in order to produce a sound.

⑰ Stretch Tuning

Stretch tuning is a piano-specific tuning method used by acoustic piano technicians in which the lower octaves are tuned slightly flatter 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 when “Normal” is selected, 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.

Type	Description
Off	Stretch tuning is disabled.

To reset the User Tuning setting to the default values, tap the [RESET] button.

⑱ Temperament

The Temperament setting allows the tuning system used by the digital piano to be changed from the modern “Equal Temperament” standard to one of the various temperaments popularised during the Renaissance and Baroque periods. It is also possible to create customised temperaments using the User Temperament function.

Temperament type	Description
Equal Temperament (Equal)	This temperament is the most popular tuning method, and divides the scale into twelve equal semi-tones. This produces the same chordal intervals in all twelve keys, and has the advantage of limitless modulation of the key. However, the tonality of each key becomes less characteristic and no chord is in pure consonance.
Pure Temperament (Pure Major/Pure Minor)	This temperament, which eliminates dissonances for thirds and fifths, is still popular in choral music because of its perfect harmony. Any key modulation will result in dissonances.
Pythagorean Temperament (Pythagorean)	This temperament, which uses mathematical ratios to eliminate dissonance for fifths, is very limited for use with chords, but produces very characteristic melodic lines.
Meantone Temperament (Meantone)	This temperament, which uses a mean between a major and minor whole tone to eliminate dissonance for thirds, was devised to eliminate the lack of consonances experienced with certain fifths for the Mersenne pure temperament.It produces chords that are more beautiful than those played with equal temperament.
Werckmeister Temperament (Werckmeister)	These two temperaments are placed in between Meantone and Pythagorean. For music with few accidentals, this temperament produces the beautiful chords of the mean tone, but as accidentals increase, the temperament produces the characteristic melodies of the Pythagorean temperament.It is used primarily for classical music written in the Baroque era to revive the original characteristics.
Kirnberger Temperament (Kirnberger)
User Temperament (User)	A custom temperament, created by raising or lowering the pitch of each note in the scale.

User Temperament

The User Temperament function allows a custom temperament to be created.
Select the [User] Temperament type, then tap the [EDIT] button to display the Temperament Editor screen.

Tap the [–] and [+] buttons in the Temperament area to adjust the value for the selected note, or swipe up and down in the keyboard graphic area of the screen.
The User Temperament value can be adjusted within the range of –50~+50.
A value of +20 indicates a pitch increase of 20 cents.
The current Temperament Key setting is shown by a symbol above the defined key.
To reset the User Temperament setting to the default values, tap the [RESET] button.

CHECK

The key of the temperament and major/minor setting must be correctly matched.

⑲ Temperament Key

The Temperament Key setting allows the key of the selected temperament to be specified. When using a temperament other than Equal temperament, use this setting to specify the key signature of the piece.

CHECK

If Equal Temperament is selected, setting the Temperament Key will have no effect.

⑳ Key Volume

The Key Volume setting allows the volume of different regions of the keyboard to be subtly reduced. There are four different damping presets available, with an additional “User” setting allowing players to perform subtle volume adjustments on each individual key. While the default “Normal” key volume setting should be appropriate for a broad range of musical genres, it may be desirable to experiment with different damping presets, or the User setting to attenuate or amplify the volume of individual keys.

Type	Description
Normal	An evenly balanced volume throughout the keyboard.
High Damping	Gradually reduces the volume of the keyboard towards the treble region.
Low Damping	Gradually reduces the volume of the keyboard towards the bass region.
High & Low Damping	Gradually reduces the volume of the keyboard in both the treble and bass regions.
Center Damping	Gradually reduces the volume of the keyboard in the central region.
User	A custom keyboard volume, allowing the volume of each key to be individually adjusted.

User Key Volume

The User Key Volume settings allows the volume of each of the 88 keys to be adjusted individually.
Select the [User] Key Volume type, then tap the [EDIT] button to display the Key Volume Editor screen.

The Volume value can be adjusted within the range of –50~+50, with lower values attenuating the sound and higher values amplifying the sound.
To reset the User Key Volume setting to the default values, tap the [RESET] button.

㉑ Half-Pedal Adjust

The Half-Pedal Adjust setting allows the point at which the damper pedal becomes effective (i.e. when the dampers of the piano begin to lift from the strings) to be adjusted. This setting may be useful for pianists that habitually rest their right foot on the damper/sustain pedal, but do not necessarily wish to sustain the sound.

Value	Description
1	This setting allows the half-pedal to start at the earliest point.
～	～
7	This setting allows the half-pedal to start at the latest point.
8	This setting is intended for using the pedal as a MIDI controller.The maximum value can be reached easily, without pressing the damper pedal fully.
～	～
10	This setting is intended for using the pedal as a MIDI controller.The maximum value will be reached when the damper pedal is pressed fully.

㉒ Soft Pedal Depth

The Soft Pedal Depth setting adjusts the extent to which the soft (left) pedal of the digital piano softens the sound of played notes. While the default value is intended to replicate the effectiveness of a concert grand Una Corda pedal, it may be desirable for players to increase or decrease the value of this setting to suit their playing style. On an acoustic grand piano, pressing this Una Corda pedal shifts the keyboard action slightly to the right, causing the hammers to strike two strings instead of the usual three, thus reducing the volume of each note.

Value	Description
1	The soft pedal will have a relatively small softening effect on the selected sound.
～	～
10	The soft pedal will have a relatively large softening effect on the selected sound.

㉓ Damper Hold

The Damper Hold setting is used to determine whether sounds such as organ or strings should be sustained continuously when the damper pedal is pressed, or whether these sounds should decay, naturally.

Type	Description
On	Organ, strings, etc. sounds will be sustained continuously while the damper pedal is pressed.
Off	Organ, strings, etc. sounds will gradually decay, even while the damper pedal is pressed.
