Selecting a temperament

equal temperament, pure temperaments (major and mi-
nor), classical temperaments (Kirnberger and Werckmeis-
ter) as well as temperaments used with Middle Eastern
and Indian folk music.

00 Equal temperament (default setting):
Spacing all semitones at equal pitch intervals,
this temperament is the most widely used.
01 Pure temperament [major]: Major chords in the
selected key are perfectly tuned.
02 Pure temperament [minor]: Minor chords in
the selected key are perfectly tuned.
03 Arabic: This scale includes the quarter-tone in-
tervals used in Arabic music.
04 Pythagorean: This ancient Greek scale is espe-
cially effective for playing melodies. It consists
of perfect fifths; however, other intervals – the
major third in particular – is out of tune.
05 Werckmeister: The Werckmeister III scale was
created in the later Baroque period to allow
relatively free transposition.
06 Kirnberger: The Kirnberger III scale is used
mainly for tuning harpsichords.
07 Slendro scale: This is an Indonesian gamelan
scale with five notes per octave.
08 Pelog scale: This is an Indonesian gamelan
scale with seven notes per octave.

About stretched tuning
In order to produce the most natural resonance, PIANO1
and PIANO2 sounds use a "stretched tuning" that makes
the notes of the lower range slightly flatter than equal tem-
perament, and the upper range slightly sharper. This is
how an acoustic piano is normally tuned by professional
tuners.
Partner mode settings

play turns the mode on (on) or off (oFF).

The right side of the keyboard, from E4 to C8, produces
sounds in a range two octaves lower (E2–C6). The left side
of the keyboard, from A0 to E
range two octaves higher (A2–E
The division for the left and right sides of the keyboard
as well as the range (pitches) cannot be changed.
In the Partner mode, the transposition settings are
ignored. In addition, keyboard information (Note On
and Note Off) is not sent with MIDI.
Selecting the sound for the left side
Exit the Function mode, and then press the sound but-
ton for the sound to be used with the left side of the
keyboard. The right side of the keyboard remains set to
the PIANO1 sound.
Selecting sounds for the left and right sides
Exit the Function mode, and then simultaneously press
the two sound buttons for the sounds to be used. The
LEDs for the two pressed sound buttons light up.
Sound for left side of keyboard
Sound for right side of keyboard
The leftmost or uppermost selected sound button is for
the left side of the keyboard, and the other (rightmost
or lowermost) one is for the right side of the keyboard.
For example, if E.PIANO1 and ORGAN1 are selected,
E.PIANO1 is for the left side of the keyboard and OR-
GAN1 for the right side of the keyboard.
In order to use sounds in different banks, first select
the banks in the Single mode for the sound buttons to
be pressed.
If the Partner mode is turned off and the Function
mode is exited with the left and right sides of the key-
board set to different sounds, the Layer mode will be
entered.
In the Partner mode, the tone performed will change
2
to Piano 1 when entering the performance of a piano
2 song. However, the tone of the keyboard on the right
that was selected in the Partner mode will be emitted
when the keyboard on the right (E4–C8) is played.
Using the same sound (other than PIANO1) for both the
left and right sides
Exit the Function mode, and then simultaneously press
two sound buttons, making sure that the rightmost
one is for the sound to be used. Then, press the right-
most selected sound button again. For example, after
pressing the PIANO2 and ORGAN1 buttons, press the
ORGAN1 button again to use the ORGAN1 sound with
both the left and right sides of the keyboard.
Changing the volume for the left and right sides
If the sounds for the left and right sides of the key-
board have been changed, the volume can be specified
for each sound. refer to "Specifying the volume balance
for layers" on page 19.
