Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. This keyboard has 12-note
polyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or auto-
accompaniment pattern is being played by the keyboard, the
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 6-note
polyphony.
• When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.
• Though you can sound up to 12 notes at one time, only the
last four keyboard keys pressed light up.
