Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 24-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 12-note
polyphony.
When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.
Digital Sampling
A number of the tones that are available with this keyboard
have been recorded and processed using a technique called
digital sampling. To ensure a high level of tonal quality,
samples are taken in the low, mid, and high ranges and then
combined to provide you with sounds that are amazingly
close to the originals. You may notice very slight differences
in volume or sound quality for some tones when you play
them at different positions on the keyboard. This is an
unavoidable result of multiple sampling, and it is not a sign
of malfunction.
