Explanation
SWITCH
OFF, ON
Specifies, for each part, whether or not the keyboard controller section will be connected to
the internal sound generator.
LOWER
C-1 –(UPPER)
Lowest note that the tone will sound for each part
UPPER
(LOWER)–G9
Highest note that the tone will sound for each part
When the KEY RANGE (p. 42) is set for each individual tone in a patch, sounds are
produced in the range where the Key Range of each tone and the Key Range for the part
overlap.
OCTAVE
-3–+3
Register of the keyboard for each part (in octave units)

Equal Temperament
This tuning divides the octave into 12 equal parts, and is the most
widely used method of temperament used in Western music. The
JUNO-Di employs equal temperament when the Scale Tune Switch
is set to “OFF.”
Just Intonation (Tonic of C)
Compared with equal temperament, the principle triads sound pure
in this tuning. However, this effect is achieved only in one key, and
the triads will become ambiguous if you transpose.
Arabian Scale
In this scale, E and B are a quarter note lower and C#, F# and G#
are a quarter-note higher compared to equal temperament. The
intervals between G and B, C and E, F and G#, Bb and C#, and Eb
and F# have a natural third-the interval between a major third and
a minor third. On the JUNO-Di, you can use Arabian temperament
in the three keys of G, C and F.
