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.
