Roland c-280 业主指南

Basic Operation—Playing

The C-280 allows you to change the temperament simply by pressing a button.

➤

Hold down the [Temperament] button, and the indicators for the various temperaments 
you can select from will successively go into the blinking state. When the indicator for 
the temperament you want is blinking, release your finger from the button. That 
temperament will then be placed in effect.
After advancing to Just Minor, you will return again to Equal.

You can select one of the following eight temperaments.

Here, notes in all scales are spaced uniformly; this is the most widely used temperament.

This is Werckmeister temperament, type 1-3.
This temperament offers greater freedom of modulation than does the Meantone, so it is popular for 
chordal compositions with key signatures having few accidentals, or for melodic playing in compositions 
featuring many accidentals.

This is Kirnberger temperament, type 3.
While providing freedom of modulation, the clear difference between the Werckmeister temperament’s 
pure thirds and those which are not pure brings out the differences in resonance from the adjustments. In 
particular, the sensation of tension is strongest in the third between A and C.

This tuning eliminates the dissonant (wolf) interval of the Pythagorean scale, and uses something 
approaching a pure third only for this interval.
Of all the temperaments here, this is closest to the Equal temperament in being without idiosyncrasies. 
The Young temperament is obtained by changing the tonic to G. As the temperament of this instrument 
centers on A, be sure to retune when playing together with another instrument.
Vallotti is suitable for keys with flats in the key signature, such as the key of F major or B flat major, and 
Young is suitable for key signatures with sharps, such as D major or E major.

This is Aaron’s meantone temperament.
This temperament is composed differently, with the pure fifth compromised to permit modulation that is 
impossible in Just tunings. The dissonant fifth between G and E when C is the tonic is preserved, 
making it possible to modulate up to three sharps and two flats in Major keys, and up to two flats in minor 
keys.

While melodic lines played in this temperament, consisting of pure fourths and fifths, resonate 
beautifully, the overt acoustic discrepancy of the thirds makes it unsuitable for harmonic playing. 
Furthermore, the dissonant (wolf) fifth is preserved (between G and E when C is the tonic), thus 
disallowing modulation.
On the other hand, in chordal applications, shifting the tonic six semitones (for example, performing in C 
Major when the Tonic is G ) and using a wolf interval between the root and the third allows you to 
achieve something very close to a Just temperament.
