RD-170 System parameters

r
maj (Just major): A tuning which resolved the
ambiguity of fifths and thirds. Quite beautiful
sonorities are produced with chords, but the
scale is unbalanced, so it is not well-suited for
melodies.
min (Just minor): This is a Just scale for playing
pieces in minor keys.
mnt (Mean Tone): A temperament that adds
some compromises to Just temperament and
facilitates transposition.
Uer (Werckmeister): A combination of the
Mean Tone and Pythagorean temperaments,
this tuning allows for playing in any key.
kir (Kirnberger): As a result of improvements
made to the Mean Tone and Just tempera-
ments, it is relatively tolerant towards transpo-
sition and can be used to play in all keys.

●Specifying the root note
When you play using a tuning other than Equal
Temperament, you need to specify the root/
fundamental (“C” for major and “A” for minor)
according to the key of the song to be played.

Stretch Tuning
“Stretch Tuning” is a tuning method specific to
pianos. The pitch of a piano is generally tuned lower
in the bass and higher in the treble compared with
equal temperament. This is done because low notes,
when tuned right, sound a little sharp, while treble
notes sound flat. By changing the tuning curve, the
chords will sound subtly different.

bass and treble. This is suitable for piano solos.

Pedal detection
You can connect either a footswitch (DP-2, etc.) or
an expression pedal (EV-7, etc.) to the RD-170’s
SOFT/EXPR. socket and specify its function for the
Upper and Lower parts separately (see p. 22).
an expression pedal (EV-7, etc.) to the RD-170’s
SOFT/EXPR. socket and specify its function for the
Upper and Lower parts separately (see p. 22).
The RD-170 is smart enough to recognize whether
you are using a footswitch or an expression pedal.
(You cannot use both simultaneously, so don’t try to
solder the cable wires together or using a multi-
input connection box.) There may be times when
you select a Setup memory (see p. 28) that assigns
the Soft function to the Upper part, for example,
while an EV-5 expression pedal is connected to the
SOFT/EXPR. socket.

If pedal detection is on, the RD-170 behaves
smartly: if you connect the “wrong” kind of perfor-
mance controller to the SOFT/EXPR. socket (an
expression pedal rather than a footswitch, for
example), you can control the Upper Part’s expres-
sion level.
