About various temperaments
Equal temperament
This temperament divides the octave into 12 equal parts,
and is the temperament that is most widely used today,
particularly for Western music. When the Scale Tune
Switch is OFF, the MC-505 will use equal temperament.
Just intonation (Tonic of C)
Compared to equal temperament, the principle triads
will harmonize more perfectly. However this effect is
obtained only in a single key, and if you modulate to a
different key, the chords will be discordant.
Arabian-style temperament
This is an Arabian-style temperament. On the MC-505,
you can enjoy Arabian-style temperament in the three
keys of G, C and F.
