To select the key signature of the temperament, simply press one of
the 88 piano keys. The LED display shows you the note name for the key you pressed and it will be chosen as the key of the temperament. For example, if the song you are going to play is written in D major, press any “D” key to set the temperament key.
BRIEF EXPLANATION OF TEMPERAMENTS
EQUAL TEMPERAMENT (PIANO ONLY)
This is the default temperament. If a piano sound is selected the tuning is stretched like an acoustic piano (EQUAL TEMPERAMENT). If any other type of sound is selected the tuning will be EQUAL (FLAT). An explantion of EQUAL TEMPERAMENT and EQUAL TEMPERAMENT (FLAT) is provided later in this section.
NOTE:
If a piano sound is used in a layer with any other sound then both sounds will use the EQUAL TEMPERAMENT (Stretched) tuning.
MERSENNE PURE TEMPERAMENT(Major)
MERSENNE PURE TEMPERAMENT(Minor)
This temperament, which eliminates dissonances for thirds and fifths is still popular for choral music because of its perfect harmony.
You need to be aware what key you are playing in with this temperament. Any key modulation will result in dissonances. When you play music in a particular key, you need to match the key of the temperament as well. When playing in a major key select Pure (Major) and when playing in a minor key select Pure (minor).
PYTHAGOREAN TEMPERAMENT
This temperament, which uses mathematical ratios to eliminate dissonance for fifths, is very limited for use with chords, but it produces very characteristic melodic lines.
MEANTONE TEMPERAMENT
This temperament, which uses a mean between a major and minor whole tone to eliminate dissonance for thirds, was devised to eliminate the lack of consonances experienced with certain fifths for the Mersenne pure temperament. It produces chords that are more beautiful than those with the equal temperament.
