Creating a Patch
Tune
fig.03-12_50
Patch Coarse Tune
Adjusts the pitch of the patch’s sound up or down in semitone steps
(+/-4 octaves).
Value:
-48– +48
Patch Fine Tune
Adjusts the pitch of the patch’s sound up or down in 1-cent steps (+/
-50 cents).
Value:
-50– +50
One cent is 1/100th of a semitone.
Scale Tune (Scale Tune Switch)
Turn this on when you wish to use a tuning scale other than equal
temperament.
Value:
OFF, ON
The V-Synth allows you to play the keyboard using temperaments
other than equal temperament. The pitch is specified in one-cent
units relative to the equal tempered pitch.
• One-cent is 1/100th of a semitone.
• The selected scale applies to MIDI messages received from an
external MIDI device.
Scale Tune C–B
Make scale tune settings.
Value:
-100– +100
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 V-Synth employs equal temperament when the
Scale Tune Switch is set to “OFF.”
Just Temperament (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 V-Synth, you can use Arabian
temperament in the three keys of G, C and F.
