2. TEMPERAMENT
The CA piano offers not only equal temperament (the modern standard)
but also immediate access to temperaments popular during the
Renaissance and Baroque periods. It should be interesting and educational
to try some of the different temperaments, although the equal temperament
is dominant today.
Press the PIANO 2 button while holding down the TOUCH and the
TRANSPOSE buttons.
The display alternatively shows “tMP” (= Temperament) and the symbol
that indicates which type of temperament is in use.
Use the VALUE buttons to change the type of temperament.
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 dissonance’s 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 dissonance’s. 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).
