Roland GR-30 Manual page 84

The "Mod" setting for the pedal effect (WAH) also
has an independent setting in effect (undulation)
depth for each tone.
→ Check the depth of the effect choose a tone
with a depth that matches the song.
One tone is not heard when the
expression pedal is used to change
the tone's volume balance
Is the TONE MIX "LAYER" setting set so that only
the first or the second tone (but not both) is played?
→ Change the setting so that the first and second
tones are both played (p. 34).
Is the TONE MIX "1:2 BAL" setting (p. 35) set to
"50" (or "-50")?
→ Change the setting to a value closer to "0" and
check operation.
The effect doesn't change even
when the expression pedal is
pulled back all the way
Is the minimum volume for the expression pedal
too high?
→ Lower the minimum volume.
The built-in effects don't have any
effect
Is the EFFECT "REVERB TYPE" setting (p. 42) or
"CHORUS TYPE" setting (p. 43) set to "oFF" (off)?
→ Choose a type other than "oFF" (off).
Is "REVERB LEVEL" too low?
→ Set "REVERB LEVEL" to an appropriate value.
Is the EFFECT BYPASS indicator lit up?
→ Press [+] while holding down [EDIT/PLAY] to
release the Bypass function.
The GR-30's built-in effects are exclusively for use
with the internal synth sounds. They are not
applied to the sounds of the guitar itself.
→ You can apply external effects for the guitar to
only the guitar sounds by using the GUITAR
OUT jack. (If you wish to use a single amp for
both the guitar and synth sounds, you should
also use the GUITAR RETURN jack as well.)
Has the expression pedal assigned with the "rE.L"
(reverb level) function (p. 49) been returned to its
raised position?
→ Depress the expression pedal.

The pitch of the synth sounds
doesn't change in the same way as
the pitch of the guitar sounds
Some tones (such as percussion instruments and
effect sounds) show different changes in pitch than
with the guitar. This is not a defect.
If Harmonist is on, scale changes for synth sounds
are different from the guitar when "ARPEGGIO/
harmony SEL" (p. 66) is set to "hAr" or "h.-b."
Noise with subtle undulations is
hear in extremely high registers
This is a phenomenon peculiar to digital sound
generators known as "aliasing noise." It may be
audible when using the slide technique or the Pitch
Shift function, but it is not a defect. The GR-30 is
designed to minimize such noise during guitar
play.
Pitch doesn't change smoothly
Is COMMON "CHROMATIC set to a value from
"on1" to "on3"?
→ Set CHROMATIC to "oFF" (off) for patches that
require continuous changes in pitch.
Is the Bend Data Thin function (p. 79) in use?
Using this function may result in a slight loss of
smoothness when pitch changes, even during nor-
mal play.
→ Do not use the Bend Data Thin function when it
is not needed.
The message "bAt" flashes on the
display when the power is turned
on
This is a warning that means that the internal bat-
tery which maintains patch and system data is
almost dead. If this message appears, data may be
lost is the battery is not replaced quickly.

Roland Service Spot.
