YDP-121
F1
Tuning
F2
Scale
In addition to the tuning method described on page 18, overall tuning can also be accom-
plished via the F1 function.
After selecting “F1”, use the [–/NO] and [+/YES] buttons to lower or raise the pitch in
approximately 0.2 Hz increments (the first time the [–/NO] or [+/YES] button is pressed
simply switches to the tuning value display without actually changing the tuning). The overall
tuning range is from 427.0 Hz to 453.0 Hz (corresponding to the A3 note’s Hz). Press the
[–/NO] and [+/YES] buttons simultaneously to recall the default value “440 Hz”.
Tenths of a Hertz are indicated on the LED display by the appearance and position of one
or two dots, as in the following example:
After selecting “
F2.Y
”, press the [+/YES] button to engage the scale function sub-mode,
then use the FUNCTION [
<
] and [
>
] buttons to select the desired scale function, as listed
below.

F2.1: Scale
..........................................................................................................................................................
In addition to the standard Equal Temperament tuning, the YDP-121 includes 6 classic
tunings that you can select and use to play music of the corresponding period, or experiment
with in a more modern context. The tunings are:
1: Equal Temperament
5: Mean Tone
2: Pure Major
6: Werckmeister
3: Pure Minor
7: Kirnberger
4: Pythagorean
Use the [–/NO] and [+/YES] buttons to select the number of the desired tuning.
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default settings (Equal
Temperament tuning).
F2.2: Base Note
.............................................................................................................................................
Unlike Equal Temperament tuning, these classic tunings must be tuned to a specific key.
Use the [–/NO] and [+/YES] buttons to select the key you want the previously selected tuning
to be based. The selected key will appear on the display, followed by a low bar if flat (e.g.
“
A_
”) or a high bar if sharp (e.g. “
F~
”).
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default settings “C”.
NOTE
• The base note setting is effective for tunings other than the Equal Temperament tuning.
