		In this tuning, each octave is divided into
		twelve equal steps. Every interval produces
1	Equal	about the same amount of slight dissonance.
		This setting is in effect when you turn on the
		power.
		This tuning, devised by the philosopher
2	Pythagorean	Pythagoras, eliminates dissonance in fourths
		and fifths. Dissonance is produced by third-in-
		terval chords, but melodies are euphonious.
		This tuning eliminates ambiguities in the fifths
3	Just	and thirds. It is unsuited to playing melodies
	Major	and cannot be transposed, but is capable of
		beautiful sonorities.
	Just	The Just tunings differ from major and minor
4		keys. You can get the same effect with the mi-
	Minor
		nor scale as with the major scale.
5	Mean Tone	This scale makes some compromises in just in-
		tonation, enabling transposition to other keys.
		This temperament combines the Mean Tone
6	Werckmeister	and Pythagorean tunings. Performances are
		possible in all keys (first technique, III).
		This is an improvement of the Mean Tone and
7	Kirn-	Just tunings that provides a high degree of free-
	berger	dom of modulation. Performances are possible
		in all keys (III).

Initial setting: C

Tonic

When playing with tuning other than equal tempera- ment, you need to specify the keynote for tuning the song to be performed (that is, the note that corresponds to C for a major key or to A for a minor key).

While holding down the [E. Piano] button, and press a note to specify the desired tonic key.

The tonic note you specify will be displayed as follows.

If you choose an equal temperament, there’s no need to select a keynote.

NOTE

•If you record with a temperament other than equal tempera- ment selected, and then want to play back that performance, use this setting to select the same temperament for playback as the temperament you used when recording.

•When performing in ensemble with other instruments, be aware that depending on the key, there may be some shifting of the pitch. Tune the ep-760 to the fundamental pitch of the other instruments.

Setting the tuning curve (Stretch Tuning)

An acoustic piano is generally tuned to a pitch with a lower bass range and a higher treble range than equal temperament. This special tuning method for pianos is called “Stretch Tuning.”

If you press the [Harpsichord] button in step B of

“Function settings”, p. 24, a display like the following will appear.

	0n
Setting range:
OFF	This is the standard tuning curve. This is the right choice
	when using Dual performance (p. 11), or when playing in en-
	semble with other instruments.
On	This tuning curve expands the bass and treble ends some-
	what. It is suitable for performances such as piano solos. This
	setting is in effect when you turn on the power.

Initial setting: On

NOTE

This effect works only with the piano tones.

Applying the damper pedal to the left half

When you are using Split performance (p. 13), you can apply the damper pedal effect to the sound played by the left-hand keyboard range.

If you press the [Organ] button in step B of “Function settings”, p. 24, a display like the following will appear.

0ff

NOTE

This function is only meaningful if you connect the supplied DP-2 footswitch to the Pedal [Damper] socket.

Setting range:

OFF	The damper pedal effect will not be applied to the sound of
	the left-hand keyboard area.
On	The damper pedal effect will be applied to the sound of the
	left and right hand keyboard area.

Initial setting: OFF
