very loud volume levels .
Check that the MASTER VOLUME slider is set to an appropriate level,
reducing the volume if excessive distortion is heard .

The pitch or sound quality with a
specific piano timbre is odd .
The CN27 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 effects that contribute to
the overall piano playing experience .
While these additional effects are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable
them altogether using the sound settings .

The pedals are unreliable or do not
function at all .
Check that the pedal cable is firmly connected to the instrument .

When depressing a pedal, the
pedal board flexes and is not firm .
Check that the pedal support bolt is fully extended .

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 CN27 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 reducing the ‘Damper Noise’ parameter using
the Virtual Technician iPad app . This sound can also be silenced by
pressing and holding the SOUND SELECT and METRONOME buttons,
then pressing the F#7 key .
