Roland LX-15 用户手册

Off, 1–10
(default: 5)

This adjusts the string resonance of the acoustic piano sound (the sympathetic vibrations of strings for previously played 

notes that occur when you play another note).
Higher settings will make the sympathetic vibration louder.

Off, 1–10
(default: 5)

This adjusts sympathetic vibrations such as an acoustic piano’s key-off sound (the subtle sound that occurs when you 

release a note).
Higher settings will make the sympathetic vibration louder.

Off, 1–10
(default: 4)

Adjusts the body resonance of the grand piano itself.
Higher values will produce a larger body resonance.

Off, 1–10
(default: 4)

This adjusts the damper noise of the acoustic piano sound (the sound of the damper releasing the strings when you press 

the damper pedal).

*  No damper noise will be heard if Damper Resonance is set to “Off.”

415 .3–440 .0–466 .2 Hz
(default: 440.0 Hz)

This adjusts the LX-15’s standard pitch (the pitch of the middle A note).
When playing ensemble with other instruments and in other such instances, you can match the standard pitch to another 

instrument.
The standard pitch generally refers to the pitch of the note that’s played when you finger the middle A key. For a cleaner 

ensemble sound while performing with one or more other instruments, ensure that each instrument’s standard pitch is in 

tune with that of the other instruments. This tuning of all the instruments to a standard pitch is called “master tuning.”

Werckmeister, Arabic
(default: Equal)

You can play classical styles such as Baroque using historic temperaments (tuning methods).
Most modern songs are composed for and played in equal temperament, the most common tuning in use today. But at one 

time, there were a wide variety of other tuning systems in existence.
By playing in the temperament that was in use when a composition was created, you can experience the sonorities of 

chords originally intended for that song.
For details, refer to “Temperaments”.

C–B
(default: C)

When playing with tuning other than equal temperament, you need to specify the temperament key for tuning the song to 

be performed (that is, the note that corresponds to C for a major key or to A for a minor key).
If you choose an equal temperament, there’s no need to select a temperament key.

(User: -50–0–+50)
(default: Preset)

This lets you specify the amount of “stretch tuning,” a tuning method specifically for pianos, in which the high range is 

tuned slightly sharper, and the low range is tuned slightly flatter.
If you select “Preset,” a standard tuning curve created for the LX-15 will be used.
If you select “User,” you’ll be able to edit the stretched tuning yourself. Play the key whose pitch you want to adjust, then use 

the [–] [+] buttons to adjust its pitch.

For some parameters, you can listen to a demo song.

In this tuning, each octave is divided into twelve equal steps. Every interval produces about the same amount of slight dissonance.

This tuning eliminates ambiguities in the fifths and thirds. It is unsuited to playing melodies and cannot be transposed, but is capable of 

beautiful sonorities.

The Just tunings differ from major and minor keys. You can get the same effect with the minor scale as with the major scale.

This tuning, devised by the philosopher Pythagoras, eliminates dissonance in fourths and fifths.
Dissonance is produced by third-interval chords, but melodies are euphonious.

This is an improvement of the Meantone and Just tunings that provides a high degree of freedom of modulation. Performances are possible 

in all keys (III).

This scale makes some compromises in just intonation, enabling transposition to other keys.

This temperament combines the Meantone and Pythagorean tunings. Performances are possible in all keys (first technique, III).

This tuning is suitable for the music of Arabia.

The Duplex Scale is a system of sympathetically vibrating strings sometimes included in grand pianos.
These sympathetically vibrating strings are not struck directly with hammers, but sound by vibrating in sympathy with the vibrations of other strings. By resonating with 

the overtones, these strings add richness and brilliance to the sound. These sympathetic strings are added only to the high register above approximately C4. Since they do 

not have a damper (a mechanism that stops them from sounding), they will continue sounding even after you play a note and then release it to stop the sound of the string 

that was actually struck.
