Dual Balance; Dual Detune - Yamaha P-255 Owner's Manual

Customizing with Function Parameters
Werckmeister
Kirnberger
The Werckmeister and Kirnberger tuning systems improve the
Meantone and Pythagorean tuning systems by combining them
in different ways. Both are uniquely characterized by the way in
which modulation can change the nuances of musical composi-
tions. Often used in the eras of Bach and Beethoven, they are
still employed today to reproduce the music of those periods on
the harpsichord.

F3. 1

Dual balance

This parameter can be used to optimize the volume balance
between the layered Voices. For example, you could set it
such that one Voice serves as the main sound and the other
provides a subtle accent or a textured after-sound.
• Available settings: 0 to 20 (The greater the value, the louder the
volume of Voice 1; 10 represents an equal balance.)
• Default setting: Each combination of Voices has its own default.
F3. 2

Dual detune

Use this parameter to slightly detune the two Voices relative
to one another in order to thicken their combined sound.
• Available settings: -20 to 0 to 20 (The more positive the value, the
higher the pitch of Voice 1 and the lower the pitch of Voice
2. The more negative the value, the higher the pitch of
Voice 2 and the lower the pitch of Voice 1.)
• Default setting: Each combination of Voices has its own default.
NOTE
• The actual amount of detuning is greater for lower notes than higher notes—for
example, ±60 cents for A-1 corresponds to ±5 cents for C7. (100 cents equal one
semitone.)
F3. 3
Voice 1 octave shift
F3. 4
Voice 2 octave shift
These parameters are used to raise or lower the pitch of
each of Voice 1 and Voice 2 in units of one octave. In cer-
tain cases, this can enhance the combined sound of the
Voices.
• Available settings: -1, 0, and 1
• Default setting: Each combination of Voices has its own default.
NOTE
• Refer to page 14 for details of what is meant by Voice 1 and Voice 2.
F3. 5
Voice 1 effect depth
F3. 6
Voice 2 effect depth
Use these parameters to set the depth of the effect for each
of Voice 1 and Voice 2.
• Available settings: 0 to 20
• Default setting: Each combination of Voices has its own default.
NOTE
• Refer to page 14 for details of what is meant by Voice 1 and Voice 2.
F3. 7
Reset
By pressing the [+/YES] button with this Function parame-
ter shown, you can reset all of the Dual mode settings to the
defaults for the corresponding Voice combinations.
