Chord Intelligence can’t be used.
● Has Chord Intelligence been switched off? (p. 147)
● Is the setting for “Piano Style Arranger” active? (p. 80)
A note doesn’t stop playing
● Have the Chord Tone and Bass Tone been changed
(p. 146)?
Some Chord Tone and Bass Tone notes may be sounded
continuously.
Recording is not possible.
● Has one of the track buttons for recording been selected?
(p. 101)
● Has the setting for “Punch-in Recording” (p. 117) or
“Tempo Recording” (p. 123) been made?
To go back to the usual recording method.
The recorded performance has disappeared.
● Any performance that has been recorded is deleted when
the power to the KF-90 is turned off or a song is selected.
A performance cannot be restored once it’s been deleted,
so be sure to save it on a floppy disk before you turn off the
power (p. 109).
The tempo of the recorded song or metronome
is not right.
● When you record after selecting an internal song that
features a changing tempo, the tempos on the other tracks
are changed in keeping with these tempo changes. In
addition, the metronome tempo is also changed the same
way.
Nothing appears on screen.
● The KF-90 uses a liquid-crystal screen, so text may not be
displayed when the ambient temperature is below
freezing.
Lyrics are not indicated properly in the
display.
● With some music files, the lyrics cannot be displayed
correctly.
● Lyrics data can not be saved on a floppy disk.
● If you press a button while the lyrics are being shown in
the display, the lyrics will disappear. To recall them, press
the Play [ ] button.
Score is not indicated properly in the display.
● In the Score screen, some lyrics or notes could extend
beyond the edges of the screen, and not be displayed.
● The score display feature is particularly unsuitable for the
display of difficult, complex musical works that demand
accurate notation.
Refer to “Some notes on a Score Screen” (p. 85).
● If you select a part that does not contain performance data,
notes will not be displayed in the score.
Change the part that is displayed (p. 149).
The Touch Screen doesn’t respond correctly.
● The positioning of the Touch Screen may become displaced
if some time has passed since it was last used. Take a look
at “Repositioning the Touch Screen” (p. 155) to correct the
positioning.
Depressing a pedal has no effect, or the pedal
effect doesn’t stop.
● Is the pedal connected correctly? (p. 16)
● Has a different function been assigned to the pedal? See
“Assigning Functions to Pedals” (p. 147).
● Normal pedal operation is automatically enabled when the
One Touch Program [Piano] button is pressed.
● Unplugging a pedal cord from the unit while the power is
on may cause the pedal’s effect to be applied without
stopping. Be sure to switch off the power to the unit before
attempting to disconnect or connect a pedal cord.
A High-Pitched Whine Is Produced
● When listening through headphones:
Some of the more flamboyant and effervescent piano tones
feature an ample high-end component, which may make
the sound appear to have metallic reverberation added.
Since this reverberation becomes particularly audible
when supplemented by heavy reverb, you may be able to
diminish the problem by reducing the amount of reverb
applied to the sound.
When listening through speakers:
Here, a different cause (such as resonance produced by the
KF-90) would be suspect. Consult your Roland dealer or
nearest Roland Service Center.
The Bass Range Sounds Odd, or There Is a
Vibrating Resonance
● When listening through speakers:
Playing at loud volumes may cause instruments near the
KF-90 to resonate. Resonation can also occur with
fluorescent light tubes, glass doors, and other objects. In
particular, this problem occurs more easily when the bass
component is increased, and when the sound is played at
higher volumes. Use the following measures to suppress
such resonance.
• Place speakers so they are 10–15 cm from walls and other
surfaces.
• Reduce the volume.
• Move the speakers away from any resonating objects.
When listening through headphones:
Here, a different cause (such as resonance produced by the
KF-90) would be suspect. Consult your Roland dealer or
nearest Roland Service Center.
Reverberation Still Audible Even with Reverb
Turned Off
● Since the KF-90’s piano sounds faithfully reproduce the
sense of spaciousness and reverberation of an actual
acoustic piano’s sound, a certain amount of reverberation
is still perceptible, even with the reverb effect deactivated.
The volume level of the instrument connected
to KF-90 is too low.
● Could you be using a connection cable that contains a
resistor?
Use a connection cable that does not contain a resistor.
