Problem
Playback stops part way
through while transferring
song data from my computer.
A tone's quality and volume
sounds slightly different
depending where it is played
on the keyboard.
When I press a button, the
note that is sounding cuts out
momentarily or there is a
slight change in how effects
are applied.
Even though I play on
different ranges of the
keyboard, the notes do not
change octaves.
Cause
Digital noise from the USB cable or
power cord caused data
communication between your
computer and Digital Keyboard to be
interrupted.
This is an unavoidable result of the digital sampling process,
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.
Performing a button operation while playing with the Auto Accompaniment, recorder, or other
functions can cause such phenomena when the Digital Keyboard switches internal tone
effects. It does not indicate malfunction.
The ranges of certain tones are limited, which means that octaves change normally up to a
certain low note or high note. With such a tone, the notes of the lowest octave will be
repeated to the left of the lowest possible note, and the highest octave will be repeated to the
right of the highest possible note. This is due do limitations in the range of the original musical
instrument for each tone, and does not indicate malfunction of the Digital Keyboard.
Action
Stop song playback, disconnect the USB
cable from the Digital Keyboard, and then
reconnect it. Next, try playing back the song
again.
If this does not solve the problem, quit the
MIDI software you are using, disconnect the
USB cable from the Digital Keyboard, and
then reconnect it. Next, restart the MIDI
software and then try playing back the song
again.
