Check/Solution
Could the Reverb Mode be set to "REMAIN"?
Change the setting to "TONE/LIVE SET. "
* However, the reverb settings won't change if you've switched tones via MIDI or in the LAYER EDIT screen.
Is there a check mark for the Pitch Bend Control Switch or Modulation Control Switch setting of the layer
(or external layer) that you want to control?
Add a check mark to the Pitch Bend Control Switch and Modulation Control Switch settings of the layer
(or external layer) that you want to control.
Is the desired function assigned to the FC1/FC2/EXT pedal?
Assign the desired function to the pedal.
Is the Damper/FC1/FC2/EXT Control Switch setting checked for the layer (or External layer) to which you
want the effect to apply?
Add a check mark to the Damper/FC1/FC2/EXT Control Switch setting for the layer (or External layer) to
which you want the effect to apply.
Is the desired function assigned to the [S1] [S2] buttons?
Assign the desired function to the [S1] [S2] buttons.
Is the S1 (S2) Control Switch setting checked for the layer (or External layer) to which you want the effect to
apply?
Add a check mark to the S1 (S2) Control Switch setting for the layer (or External layer) to which you want the
effect to apply.
Is the desired function assigned to the Assign 1-5 controllers?
Assign the desired function to the Assign 1-5 controllers.
Is the Assign 1–5 Control Switch setting checked for the layer (or External layer) to which you want the
effect to apply?
Add a check mark to the Assign 1–5 Control Switch setting for the layer (or External layer) to which you want
the effect to apply.
Have you selected the layer to which you want the effect to apply?
In the Modulation FX Control Destination settings, select the layer to which you want the effect to apply.
Have you selected the layer to which you want the effect to apply?
In the Tremolo/Amp Control Destination settings, select the layer to which you want the effect to apply.
Have you selected the layer to which you want the effect to apply?
In the Tone Color Control Destination settings, select the layer to which you want the effect to apply.
This is due to the nature of an LCD screen; it does not indicate a malfunction.
In order to display high-quality images, the RD-800 uses a TFT liquid crystal display.
Due to its characteristics, a TFT liquid crystal screen may contain pixels that do not light or that remain lit;
please be aware that this is not a malfunction or defect.
Is the pedal connected correctly?
Plug the cord firmly into the pedal jack.
Are you using a pedal made by another manufacturer?
Use the included pedal or a separately sold RPU-3 or EV-5
Are you using (optional) Roland USB flash drive?
Reliable performance cannot be guaranteed if you use non-Roland USB flash drive products.
Execute the Format operation.

The RD-800's piano sound faithfully simulates the depth and resonance of an acoustic piano, and this may
give the impression of reverberation even if you've defeated the Reverb effect.
On an acoustic piano, the approximately one and a half octaves of notes at the upper end of the keyboard
will continue sounding regardless of the damper pedal. These notes also have a somewhat different timbre.
The RD-800 faithfully simulate this characteristic of acoustic pianos. On the RD-800, the range that is
unaffected by the damper pedal will change according to the key control setting.
Piano sounds that have a brilliant and crisp character contain substantial high-frequency components that
may sound as though a metallic ringing has been added. This is because the characteristics of an actual
piano are being faithfully reproduced; it does not indicate a malfunction. You can adjust this ringing by
editing the following settings.
• Duplex scale settings (p. 32)
• String resonance settings (p. 32)
• Reverb level (p. 31)
With certain tones, the sounds may seem to be distorted.
Turn down the volume. Alternatively, lower the master gain setting.
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
