Detailed Settings for Each Function
Selecting the Number of Parts (Part Mode)
This selects the number of parts for the RD-300NX.
Parameter Value Description
Part Mode
16PART
If you select “16PART,” the
keyboard part you yourself play
can use the same part as the
song data, meaning that you
can specify program changes
or bank selections within the
song data so that the tone of the
keyboard part will be switched
automatically.
16PART+PERF
(Performance)
When set to “16PART+PERF,” the
performance on the keyboard is
not affected by MIDI messages
from the MIDI IN connector or
song data played by the RD-
300NX. This is useful when you
want to perform on the keyboard
while playing song data with the
RD-300NX.
Setting the Tuning Method
(Temperament/Key)
This sets the tuning and keynote (tonic).
Most modern songs are composed and played with the assumption
that equal temperament will be used, but when classical music was
composed, there were a wide variety of other tuning systems in
existence. Playing a composition with its original tuning lets you enjoy
the sonorities of the chords that the composer originally intended.
When playing with tuning other than equal temperament, you need
to specify the keynote 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
keynote.
Parameter Value Description
Temperament
EQUAL
Equal Temperament
This tuning divides an octave
into 12 equal parts. Every interval
produces about the same
amount of slight dissonance.
JUST MAJ
Just (Major)
This scale eliminates dissonance
in fifths and thirds. It is unsuited
to playing melodies and cannot
be transposed, but is capable of
beautiful sonorities.
JUST MIN
Just (Minor)
The scales of the major and
minor just intonations are
different. You can get the same
effect with the minor scale as
with the major scale.
PYTHAGORE
Pythagorean
This scale devised by the phi-
losopher Pythagoras eliminates
dissonance in fourths and fifths.
Dissonance is produced by third-
interval chords, but melodies are
euphonious.
KIRNBERGE
Kirnberger
This scale is a modification of the
meantone and just intonations
that permits greater freedom
in transposition to other keys.
Performances are possible in all
keys (III).
Parameter Value Description
Temperament
MEANTONE
Mean Tone
This scale makes some
compromises in just intonation,
enabling transposition to other
keys.
WERCKMEIS
Werckmeister
This is a combination of the
mean tone and Pythagorean
scales. Performances are possible
in all keys (first technique, III).
ARABIC
Arabic Scale
This scale is suitable for Arabic
music.
Temperament Key
C, C#, D, Eb, E, F, F#,
G, G#, A, Bb, B
