Troubleshooting

If the VR-760 does not function in the way you expect, first check the following points. If this does not resolve the problem,
consult your dealer or a nearby Roland Service Station.
* If certain messages appear in the display during operation, please refer to "Messages and Error Messages" (p. 90).
Problem
No power
No sound/Low
volume
No organ part sound
Sounds play again
when the keys are
released
Hold pedal does not
work on the organ
part
Overdrive not being
applied to organ
No sound from the 1'
harmonic bar
Check
The power cable is not connected to the
VR-760 or to the power outlet.
The power to the connected device is
not turned on.
The amp, mixer, or other external device
is not properly connected.
The VR-760's volume level is low.
The volume level for the connected amp
or mixer is low.
A part's volume level is low.
The expression pedal has not been
depressed.
(When sounds are heard from the
headphones)
Local Control is set to OFF.
All of the harmonic bars are completely
pushed in.
The wheel brake is audible.
The organ volume is turned down.
To enable glissandos and rapidly
repeated notes with the organ part,
sounds are produced with a shallow
stroke (Quick Firing keyboard). This
results in the keys rebounding when
they are released quickly, causing the
notes to be played a second time.
However, this is characteristic of
traditional organs, and does not
indicate a malfunction.
Organ Damper SW is set to OFF.
The expression pedal is tilted all the
way back.
PERCUSSION is turned on. Sounds
from the 1' harmonic bar are not played
when PERCUSSION is on.
Solution
Confirm that the power cable is
properly connected.
Turn on the power to the amp, mixer, or
other connected device.
Use an optional audio cable to properly
connect the amp, mixer, or other device
to the VR-760.
Turn the [MASTER VOLUME] knob to
the right (clockwise) to raise the
volume.
Raise the volume on the amp, mixer, or
other connected device.
Turn the [ORGAN VOLUME], [PIANO
VOLUME], or [SYNTH VOLUME] knob
to the right (clockwise) to raise the
volume of the corresponding part.
Depress the pedal completely while
carefully monitoring the volume level.
If sounds are audible from the
headphones, the problem may be a
short in the cable connecting the amp or
mixer, or the amp or mixer may be
damaged or malfunctioning. Check the
cable connections and the other devices
again.
Set Local Control to ON.
Pull out one or more of the harmonic
bars.
Press the foot switch to release the
wheel brake.
Turn the [ORGAN VOLUME] knob to
the right (clockwise) to raise the volume
of the organ part.
You can turn off the Quick Firing
function. When using MIDI to play
sounds from an external sound
generator, we recommend using the
external part.
You can have the hold pedal applied to
the organ part by setting Organ Damper
SW to ON.
Press the pedal forward while carefully
monitoring the volume level.
This is not a malfunction.
