Basic Function-parameter operations

1
Press the [FUNCTION] button as many
times as necessary to select the param-
eter you wish to set.
Each time you press the [FUNCTION] button, the
parameter number shown will increase by one.
You can also decrease the number being shown by
pressing the [-/NO] button with the [FUNCTION]
button held down.
If you take no action for three seconds with a
Function parameter number being shown, the dis-
play will return to the previous screen.
NOTE
• You cannot set Function parameters during song playback (page 21),
recording (page 25), or file operations (page 30).
2
Press the [-/NO] or [+/YES] button to
enable parameter setting.
Pressing the [-/NO] or [+/YES] button once shows
the current setting for the selected Function
parameter.
3
Change the setting using the [-/NO] and
[+/YES] buttons.
If necessary, you can restore the parameter's
default setting by pressing the [-/NO] and
[+/YES] buttons together.
4
Press the [FUNCTION] button to apply
your new setting.
After three seconds, the display will return to the
previous screen.

Descriptions of Function parameters

F1.
Tuning
Using the Tuning setting, you can fine tune the pitch of the
entire instrument. This can be extremely useful when play-
ing your digital piano along with other instruments or
recorded music.
NOTE
• Audio song playback cannot be tuned.
Using the [-/NO] and [+/YES] buttons, you can lower and
raise the pitch of the A3 key in units of approximately 0.2
Hz. The tuning value is shown as a two-digit number with
one decimal place—in other words, no value is shown for
the hundreds column.
Example: 440.2 Hz is shown as "
• Available settings: 414.8.0 to 466.8 (Hz)
• Default setting: 440.0 (Hz)
Hertz
Hertz (Hz) is the unit of audio pitch. The pitch of a sound is
determined by the frequency of its sound waves. The Hertz unit
expresses this frequency in terms of the number of oscillations
per second.

Tuning system settings
Your digital piano supports a range of different tuning sys-
tems. While the Equal Temperament tuning system has now
become standard for pianos, a wide number of other sys-
tems were developed over the centuries before it was
adopted, and these systems invariably paved the way for the
birth of new musical styles. By selecting different tuning
systems, you can enjoy the unique harmonics of music from
the corresponding periods. In total, your digital piano can
replicate the following seven different systems.
Equal temperament
The range of pitches in each octave is divided equally into
twelve parts, with each half-step evenly spaced in pitch. Today,
this is by far the most popular tuning system for pianos.
Pure Major and Pure Minor
These two tuning systems preserve the pure mathematical
intervals of each scale, especially for triadic chords (comprising
the root, third, and fifth). These characteristics can still be heard
today in vocal harmonies—such as choirs and a cappella sing-
ing.
Pythagorean
This tuning system was devised by the famous Greek philoso-
pher Pythagoras and is created from a series of perfect fifths,
which are collapsed into a single octave. The thirds in this tun-
ing are not so smooth, but the fourths and fifths are beautiful
and suitable for some leads.
Meantone
This tuning system was created as an improvement on the
Pythagorean scale by making the major third interval smoother.
It was especially popular from the latter part of the 16th century
to the end of the 18th century, with Handel being one of its most
notable users.
