Additional Features; Adjusting The Pitch; Choosing A Temperament; The Brightness Of The Sound (Brilliance) - Korg HT-70 Bedienungsanleitung

As an electronic piano, the HT-70 offers numerous convenient features
that you can easily use to adjust the instrument's sound, characteristics,
and operation.

Adjusting the Pitch

The built-in pitch control function allows you to make fine adjustments
to the HT-70's pitch. You can use this feature, for example, to adjust the
HT-70 so that it is in tune with other instruments.
You can adjust the pitch by up to ±25.0 Hz, in 0.5Hz increments. Adjust-
ment is made with respect to note A4, which has standard pitch of 440.0
Hz and can be adjusted over the range 415.0 Hz to 465.0.Hz.
1. Be sure that the [SONG] LED is off, and press [FUNC.].
The [FUNC.] LED lights up.
2. Press [DISPLAY] several times, until "tUn" appears on the multidis-
play.
When you release the switch, the multidisplay shows the last three
digits of the current pitch setting. (The factory setting is 40.0.)

Choosing a temperament

The HT-70 lets you choose from several temperaments (scale tunings).
Many classical compositions were composed in historical eras in which
the notes of a keyboard scale were tuned somewhat differently than the
"equal temperament" commonly used today. For historically authentic
performances of such music, the HT-70 lets you choose the Werckmeister
or Kirnberger historical temperaments as well as the equal temperament
used on most modern keyboard instruments.
• Werckmeister
This is the Werckmeister III scale created by the German organist and
music theoretician Andreas Werckmeister. This temperament was
created in the late Baroque era to allow relatively free modulation
between keys.
• Kirnberger
This is the Kirnberger III scale created by Johann Phillip Kirnberger in
the early 18th century. This temperament is used mainly for tuning
harpsichords.
• Equal temperament
This is the temperament used by virtually all modern keyboard
instruments. In this temperament, every semitone is an equal dis-
tance apart, allowing you to play consistently in any key.

This setting reverts to its factory default (equal temperament) when
you change the position of the sound selector and when you turn
the power off.
The Piano 1 and Piano 2 sounds use "stretched tuning." In compar-
ison to the equal tempered pitched, stretched tuning slightly lowers
the pitch of the low notes and slightly raises the pitch of the high
notes in order to create a more natural-sounding resonance.
