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.
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.
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.
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 “
40.2
”.
• A v aila b le settings: 414.8.0 to 466.8 (Hz)
• Defa u lt setting: 440.0 (Hz)
Hertz
Hertz (Hz) is the u nit of a u dio pitch. The pitch of a so u nd is
determined b y the freq u ency of its so u nd wa v es. The Hertz u nit
expresses this freq u ency in terms of the n u m b er of oscillations
per second.
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 octa v e is di v ided eq u ally into
twel v e parts, with each half-step e v enly spaced in pitch. Today,
this is b y far the most pop u lar t u ning system for pianos.
Pure Major and Pure Minor
These two t u ning systems preser v e the p u re mathematical
inter v als of each scale, especially for triadic chords (comprising
the root, third, and fifth). These characteristics can still b e heard
today in v ocal harmonies—s u ch as choirs and a cappella sing-
ing.
Pythagorean
This t u ning system was de v ised b y the famo u s Greek philoso-
pher Pythagoras and is created from a series of perfect fifths,
which are collapsed into a single octa
v e. The thirds in this t u n-
ing are not so smooth, bu t the fo u rths and fifths are b ea u tif u l
and s u ita b le for some leads.
Meantone
This t u ning system was created as an impro v ement on the
Pythagorean scale b y making the major third inter v al smoother.
It was especially pop u lar from the latter part of the 16th cent u ry
to the end of the 18th cent u ry, with Handel b eing one of its most
nota b le u sers.
