feel more natural and comfortable.

Adjusting Support Bolts

Before playing for the rst time, adjust the support bolts under the

pedals to ensure that the bottom ends of these bolts are fully attached

to the ground, so that each pedal can properly withstand the force

of pedaling. Leaving support bolts mid-air can make pedaling feel

unsteady and may even cause damage to pedal bases.

An Introduction to Classical Temperaments

Twelve-Tone Equal Temperament (12-TET)

12-TET is a tuning system that divides the octave into 12 equal intervals. This tuning system only has one type

of half-tone and one type of whole-tone, making it easy to transpose. Most keyboard instruments worldwide are

tuned in 12-TET.

Just Intonation Major and Minor (Pure Major and Minor)

Just Intonation is a tuning system that generates all other intervals using natural fths and thirds. It works best for

harmonies such as choral singing or solo singing.

Tuning has larger whole tones and smaller half-tones.

Meantone Temperament

Mean-Tone Temperament was created to practically apply Just Intonation on keyboard instruments. One feature

of this temperament is that it can produce consonant sounds that are very close to Just Intonation when forming

triads. It was prevalent in Europe for hundreds of years, for its simpler construction compared to Just Intonation.

Werckmeister Temperament

Werckmeister Temperament is an improvement on the Pythagorean tuning system, proposed by the German

organ craftsman and music theorist Andreas Werckmeister.

Kirnberger Temperament is a tuning system proposed by Johann Philipp Kirnberger, a student of Johann

Sebastian Bach. After studying Bach’s “Well-Tempered Clavier,” Kirnberger developed a tuning system that is

somewhat a combination of Mean-Tone Temperament and Just Intonation, and an improvement to the Mean-

Tone Temperament.

playbacks

Check if the [VOLUME] knob is set too low. If so, turn clockwise to increase

the volume.

Check if the volume for each sound part or playback is set too low. If so,

adjust accordingly. (page 29)

Unplug headphones or convertors from [PHONES] jacks.

The speaker mode may be set as “Always OFF”. (page 37)

The instrument makes noise

When using a mobile phone nearby (especially when receiving calls), the

instrument might make noise due to interference.

Move the mobile phone slightly away from the instrument.

Check if pitch shift functions (page 19, 32) are set to non-"0". If so, reset to

"0".

The le name in the USB drive is not

displayed properly

The instrument supports Chinese and English displays. If the le name

contains characters & symbols unrecognized by the system, it may be

displayed improperly.

Bluetooth pairing is not successful

Make sure that the external device supports Bluetooth and has the Bluetooth

function turned on.

Some menus are not displayed in English

This is caused by the limited memory during the initialization of the system's

language resources, which is normal.
