Display
Touch sensitivity
1
Light. Loud notes can be produced even by
playing lightly.
2
Normal. Normal piano touch.
3
Heavy. Loud notes can be produced only by
playing very hard.
When the instrument is turned on, the touch setting is
reset to Normal.
The settings are applied to all sounds.
Transpose
In some cases, a song may be written in a difficult key (e.g.,
many black keys), or you may wish to shift the pitch to
match another instrument or vocalist. In such cases, you
can transpose (shift the pitch) so that you can use an easier
fingering, or use the same familiar fingering to play at a
different pitch. This is called the Transpose function.
For example if you transpose upward by one semitone,
playing the notes shown at the lower left will produce the
pitches shown at the right.
When the instrument is turned on, the transposing is
reset.
While holding down the TRANSPOSE button, press the
#
keyboard key (F
6–F7) for the desired transposition.
If a keyboard key other than C7 is pressed, the TRANS-
POSE LED lights up to indicate that the keyboard is trans-
posed.
The pitch of the entire keyboard is transposed according
to the pitch of the pressed keyboard key in relation to C7.
To return to the original pitches, hold down the TRANS-
POSE button and press the C7 key. The TRANSPOSE LED
turns off, and transposition is canceled.
