Parameter Value Description
SCALE TUNE SWITCH OFF, ON Turn this on when you wish to use a tuning scale other than equal temperament. The XV-
2020 allows you to use temperaments other than equal temperament.
KEY C–B SCALE
(Key Scale C–B)
-64–+63 Adjusts the pitch of each note in one-cent steps (1/100th of a semitone) relative to its
equal-tempered pitch.
• Equal Temperament
This scale divides an octave into 12 equal parts using the tuning system that is most widely used in
Western music.
• Pure Temperament (Tonic is C)
With this tuning, the three fundamental chords sound richer compared to equal temperament. This
effect only applies to one key, and transposition can produce less-pleasing results.
• 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 XV-2020, you can
use Arabian temperament in the three keys of G, C and F.
