A tone’s quality and volume
sounds slightly different
depending where it is played on
the keyboard.
This is an unavoidable result of the digital sampling process,
*
and does not indicate malfunction.
* Multiple digital samples are taken for the low range, middle range, and high range of the original
musical instrument. Because of this, there may be a very slight difference in tonal quality and
volume between sample ranges.
When I press a button, the note
that is sounding cuts out
momentarily or there is a slight
change in how effects are
applied.
Performing a button operation while playing with the Duet Mode, Auto Accompaniment, the
recorder, or other functions can cause such phenomena when the Digital Piano switches internal
tone effects. It does not indicate malfunction.
