When Changing Patch
Settings
The display suddenly starts flash-
ing
The flashing green of the EDIT PATCH indicator
shows that the currently called-up patch has been
changed or modified in some way, or that a write
operation has not been carried out. (In the Play
mode, this flashes red as a warning.)
Flashing of the text display when the STRING
SELECT knob has been set to ALL (all strings) as a
valid setting means that the current setting differs
according to the string.
The sound doesn't vary when the
settings are changed
the GR-30's Attack, Release, and Brightness set-
tings are intended to adjust the original data
belonging to each tone. This means that the range
of change differs according to the tone, and some
tones may not show much of a change.
Is the setting being changed one of the five settings
that can be made independently for each string (see
the following item), and is the setting affecting only
a particular string?
→ Turn the STRING SELECT knob to "ALL."
Settings cannot be made indepen-
dently for individual strings
Is the setting one that cannot be made for individ-
ual strings?
→ The five settings that can be made indepen-
dently for each of the strings using the STRING
SELECT knob are TONE MIX "Layer," "TRANS
1ST," and "TRANS 2ND," and MIDI "PG
CHNG#" and "TRANSPOSE."
No reverb is applied even when
the reverb level is increased
Is the EFFECT BYPASS indicator lit up?
→ Press [+] while holding down [EDIT/PLAY] to
release the Bypass function.
Is "REVERB TYPE" set to "oFF" (off)?
→ Choose a type other than "oFF" (off).
when Playing the GR-30 sound
generator with a MIDI
Keyboard or Other Instrument
No sound is heard
Do the MIDI channels for sending and receiving
match?
→ Make sure the MIDI channels match (p. 71).
The sending of Note messages and the like also
stops for patches for which MIDI "PG CHNG#" is
set to "oFF" (off).
→ Change the setting to a value from "1" to "128"
(p. 72).
Chords are not played, or key-
board damper play is not received
Is the "Poly Mode Reception" (p. 82) in use? MIDI
receiving by the GR-30 is normally fixed at the
Mono mode. (Data is received in the Mono mode
even if "transmission in Poly mode" is selected for
the MIDI CHANNEL setting.) Also, MIDI Control
Change No. 64 (damper pedal) is responds only
when receiving in Poly mode.
→ Switch on the power while holding down the [+]
button to call up the function.
The P-GLIDE and HOLD pedal effects
don't work
The Hold and Pitch Glide functions cannot be used
when play is controlled by MIDI messages from an
external instrument (such as a keyboard).
→ Use the controls on the external instrument to
apply pitch bending and holds.
Single notes are sounded when MIDI
messages are sent from the external
instrument, but messages such as
Program Change are not received
While the GR-30 is receiving in Mono mode, are
MIDI messages being sent to the five channels
other than the first channel specified by the MIDI
"CHANNEL" setting? MIDI messages other than
Note messages and Bend messages must be sent to
the first channel.
→ Be sure to send data from the external instru-
ment to the first matching channel, even when
the GR-30 is set up to receive data on six chan-
nels.
Arpeggiator doesn't work
→ Please note that Arpeggiator doesn't operate
when using the Poly Mode Receive function.
