TUTORIAL: BASIC OPERATIONS
You can adjust the volume balance between the two sounds. Use the
Dual/Split Balance slider to adjust the balance. Move the slider to
the right to increase the volume of the upper sound and decrease the
volume of the lower sound. The balance changes in the opposite way
when the slider is moved to the left.
The split point determines where the upper keyboard section will be
divided from the lower one. You can move the split point to any key you
like. To do this, please read "7. Split Button" in the Reference section,
page 44.

ABOUT POLYPHONY

The CN piano is capable of playing up to 64 notes simultaneously (64-
note polyphony). When playing in dual mode or when playing the stereo
piano sound, the polyphony will be reduced by half since the piano has to
produce two sounds for each note.
You might have noticed that when you select some of the preset sounds,
the LED indicator for the EFFECTS is turned on. The reason for this is
some of the preset sounds are set up with an effect on as their initial
setting.
Adding an effect to the sound enhances tonal quality and improves
acoustical realism. The CN piano is provided with two separate groups
of effects. The first is reverb and the second contains chorus, delay,
tremolo, and rotary speaker.
REVERB
Reverb adds reverberation to the sound, simulating the acoustic
environment of a recital room, stage, or concert hall. There are five types
of reverb available. They are Room, Stage, Hall, 3D Room and 3D Hall
(listed in order of reverberation amount).
CHORUS
Chorus is an effect that simulates the rich character of a vocal choir or
string ensemble, by layering a slightly detuned version of the sound over
the original to enrich it.
DELAY
Delay is an effect that adds echoes to the sound. There are three types of
delay available (delay 1 - 3), each of which has a different length of delay
between the echoes.
