Selecting a temperament
There are numerous classical compositions that were composed using tempera-
ments that differ from the “equal temperament” commonly used today.In order to
reproduce the original sound of such compositions, the SP-200 provides Kirnberger
and Werckmeister classical temperaments, in addition to the equal temperament,
allowing you to select from a total of three temperaments.
To select one of the available temperaments, hold down the TOUCH button, then
press the button corresponding to the desired temperament. To return to the equal
tuning hold down the TOUCH button, then press the sound selection button whose
LED is lit.
To check the currently selected temperament, hold down the TOUCH button, and
look at which of the above LEDs is turned on.
Note: When the power is turned on, the equal temperament will be automatically
selected.

temperament. This temperament spaces all semitones at equal dis-
tances, and allows identical scales to be played in any key.
