Strange sounds or noises are
heard when playing with piano
sounds.
The KDP120/KDP75 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
eects that contribute to the overall piano playing experience.
While these additional eects 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 top 18 notes of the

grand piano.
