Symptom
Some notes are cut off while they are playing.
The volume or tone setting I made has changed.
Output volume does not change even though I
change my keyboard touch.
In certain keyboard ranges, the volume and tone
quality sound are slightly different from those in other
keyboard ranges.
With some tones, octaves do not change at the far
ends of the keyboard.
The pitch of the notes does not match other
accompanying instruments or sounds strange when
played along with other instruments.
The reverb of notes seems to change suddenly.
Operation
When I perform a skip forward or skip back
operation, the skip operation moves multiple song
measures instead of only a single measure.
Tone, rhythm, and other settings revert to their initial
defaults whenever you turn on the Digital Piano.
Computer Connection
I can't exchange data between the Digital Piano and
a computer.
