Pedal Has No 

Effect, or Effect 

“Sticks”

Is the pedal connected correctly? 

Connect the pedal securely to the Pedal jack 

Unplugging a pedal cord from the unit while 

the power is on may cause the pedal’s effect 

to be applied nonstop. 

Be sure to switch off the power to the unit 

before attempting to disconnect or connect a 

pedal cord (p. 10).

Reverb Remains 

Even After Reverb 

is Lifted

As the FP-3 piano sounds faithfully repro-

duce the depth and reverberation of actual 

acoustic pianos, reverberation may still be 

audible even after the reverb effect is 

removed from sounds.

Sound Suddenly 

Changes at Key in 

Upper Octaves

With the acoustic piano settings, sounds in 

the upper 1 1/2-octave range are extended to 

the end regardless of the damper pedal 

actions. The tone is also different in this 

range. Roland’s pianos faithfully reproduce 

the sonic qualities of acoustic pianos. Fur-

thermore, you can use the instrument’s Key 

Transpose setting to change that range over 

which the damper pedal has no effect.

High-Pitched 

Whine is Produced

When listening through headphones: 

Certain piano tones that feature vibrant, 

sparking sounds contain a large high-fre-

quency component, which may make it 

appear that a metallic reverberation has been 

applied. This faithfully reproduces the char-

acteristics of acoustic pianos, and does not 

indicate any malfunction. Since this reverber-

ation 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 FP-3) would be suspect. 

Consult your Roland dealer or nearest 

Roland Service Center.

Cause/What to do

Low End Sounds 

Are Strange/Have 

a Rattling Sound

When listening through speakers: 

Playing at loud volumes may cause instru-

ments near the FP-3 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 reso-

nance. 

- Place speakers so they are 10–15 cm from 

walls and other surfaces. 

- Reduce the volume. 

- Move the speakers away from any resonat-

ing objects. 

When listening through headphones: 

The cause lies somewhere else. Consult your 

Roland dealer or nearest Roland Service Cen-

ter.

Use a connection cable that does not contain a 

resistor.
