Basic Operation
The keyboard automatically selects the tone
GRAND PIANO (No. 000) when you turn the
power on. Each time you turn it on after that, it
selects the last selected tone. To select a
different tone, see “Using the Preset Tones”.
Using the Preset Tones
The keyboard has 32-note (maximum)
polyphonic sound. This means that you can
play up to 32 different notes at the same
time with most of the keyboard’s preset
tones. Some tones are only capable of 16-
note polyphony.
Most tones on 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 are then
combined to sound amazingly close to the
originals. You might 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
is not a malfunction.
Repeatedly press + or – to select the next
highest or lowest numbered tone.
If you enter an incorrect first digit, press
TONE to clear your entry, then enter the
correct digit.
When you select one of the drum sets (tone
numbers 228–237), each key plays a
different percussion sound. See “Drum
Assignment List” on Page 30. The drum set
sounds change when you change the
rhythm number, play back data stored in
memory, or receive MIDI program change
data.
Tone numbers 238–247 are the user tone
area. See “Using the Tone Synthesizer” on
Page 13.

Mixer” on Page 12.
