Some characters of the file/folder name are garbled.
The language settings have been changed. Set the appropriate
language for the file/folder name (page 18).
An existing file is not shown.
The file extension (.MID, etc.) may have been changed or deleted.
Manually rename the file, adding the appropriate extension, on a
computer.
Data files with names of more than 50 characters cannot be han-
dled by the instrument. Rename the file, reducing the number of
characters to 50 or less.
Voice
The Voice selected from the Voice Selection display does not
sound.
Check whether or not the selected part is turned on (page 35). If
necessary, press the appropriate PART ON/OFF button to turn the
part on.
A strange “flanging” or “doubling” sound occurs. The sound is
slightly different each time the keys are played.
The RIGHT 1 and RIGHT 2 parts are set to “ON,” and both parts
are set to play the same Voice. Turn off the RIGHT 2 part or change
the Voice of one of the parts.
Some Voices will jump an octave in pitch when played in the
upper or lower registers.
This is normal. Some Voices have a pitch limit which, when
reached, causes this type of pitch shift.
Style
The Style does not start even when the [START/STOP] button is
pressed.
The Rhythm channel of the selected Style may not contain any
data. Turn the [ACMP] button on and play left-hand section on the
keyboard to sound the accompaniment part of the Style.
Only the rhythm channel plays.
Make sure the Auto Accompaniment function is turned on; press
the [ACMP] button.
Make sure to play keys in the chord section of the keyboard (pages
58, 59).
The Track Mute function may have been assigned to the LIVE
CONTROL knob(s). Check the knob settings and reset the value
(page 40).
Styles in a USB flash drive cannot be selected.
If the size of the Style data is large (about 120 KB or greater), the
Style cannot be selected because the data is too large to be han-
dled by the instrument.
Song
Songs cannot be selected.
This may be because the language settings have been changed.
Set the appropriate language for the Song file name.
If the size of the Song data is large (about 300 KB or greater), the
Song cannot be selected because the data is too large to be han-
dled by the instrument.
Song playback does not start.
The Song has been stopped at the end of the Song data. Return to
the beginning of the Song by pressing the SONG [J] (STOP) but-
ton.
In the case of a Song to which write-protect has been applied,
there are some restrictions and playback may not be possible. For
details, refer to page 27.
Song playback stops before the Song is finished.
The Guide function is turned on. (In this case, playback is “waiting”
for the correct key to be played.) Press the [GUIDE] button to turn
off the Guide function.
The measure number is different from that of the score in the
Song Position display, shown by pressing the [G](REW)/
[H](FF) buttons.
This happens when playing back music data for which a specific,
fixed tempo is set.
When playing back a Song, some channels do not play.
Playback of these channels may be set to “OFF.” Turn playback on
for those channels that are set to “OFF” (page 65).
The tempo, beat, measure and music notation is not displayed
correctly.
Some Song data for the instrument has been recorded with special
“free tempo” settings. For such Song data, the tempo, beat, mea-
sure and music notation will not be displayed correctly.
