The sound distorts when playing at
very loud volume levels.
Check that the MASTER VOLUME slider is set to an appropriate level,
reducing the volume if excessive distortion is heard.
p. 14
The pitch or sound quality with a
specic piano timbre is odd.
The CA49 digital piano attempts to reproduce the rich variety of tones
created by an acoustic grand piano as accurately as possible. This
includes damper resonances and other subtle eects that contribute to
the overall piano playing experience.
While these additional eects are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable
them altogether using the sound settings.

Pedals
The pedals are unreliable or do not
function at all.
Check that the pedal cable is rmly connected to the instrument. p. 58
When depressing a pedal, the
pedal board exes and is not rm.
Check that the pedal support bolt is fully extended. p. 15
The top 18 notes of the
keyboard sustain for longer than
neighbouring notes, even when
the damper pedal is not pressed.
This is the correct behaviour, and intended to reproduce the undamped
notes (typically the top two octaves) of an acoustic grand piano.
—
The instrument produces a
“swoosh” sound when the damper
pedal is pressed.
The CA49 digital piano reproduces the sound of dampers on a grand
piano touching and releasing the strings. If this intentional sound is
undesirable, it may be prevented by selecting the “Noiseless” Virtual
Technician preset, or by adjusting the “Damper Noise” setting.
