Strange sounds or noises are heard
when playing with piano sounds.
The CA93/CA63 digital piano attempts to reproduce the rich variety
of tones created by an acoustic grand piano as accurately as possible.
This includes string resonances and damper noises, and other subtle
characteristics that contribute to the overall piano playing experience.
While these additional tones are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable the
eects altogether using the functions in the Virtual Technician menu.
