■ When Sending Performance
Data from the GR-30 to an
External MIDI Device (sound
generator or Sequencer)
●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●
● No sound from the external sound
generator
◆ Do the MIDI channels for sending and receiving
match?
→ Make sure the MIDI channels match (p. 71).
◆ The volume level of the external sound generator
may have been lowered by a MIDI Volume mes-
sage (Control Change No. 7) sent from the GR-30.
→ Raise the volume on the GK-2A.
◆ Is the volume for the GK-2A or expression pedals
too low?
→ Use the controls to increase the volume.
● The external sound generator plays
only one string (some strings can’t be
heard)
◆ Is the GR-30 using the Mono mode to send data to
a sound generator which cannot simultaneously
receive data on six MIDI channels?
→ For such sound generators, send data in the
Poly mode (p. 72).
● Notes in a bass register not on the
guitar cannot be played
→ Output from MIDI OUT can be transposed as
desired by changing the MIDI “TRANSPOSE”
setting (p. 76).
● The pitch is wrong (out of tune with
the guitar)
◆ Is MIDI Bend Range the same for both sending and
receiving?
→ If the pitch is off, adjust the Bend Range setting
(p. 71).
● Pitch doesn’t change smoothly
◆ Is data being sent in the Poly mode? When trans-
mitting in the Poly mode, pitch changes during
chord performances are in semitone steps (p. 72).
→ Play with single notes, or use the Mono mode
to send data.
◆ Is the Bend Data Thin function (p. 79) in use?
→ Do not use the Bend Data Thin function when it
is not needed.
◆ Is MIDI “BEND RANGE” set to “1” or “2”?
→ When matching with sending and receiving,
use as large a value as possible (p. 71).
◆ When “BEND RANGE” is set to “0”, the pitch
changes in semitone steps.
→ Change the setting to a preferable value.
● The Note messages input to the
sequencer don’t look like the scale
that is actually played
◆ To start playing sounds rapidly and achieve
smooth changes in pitch, the GR-30 transmits pitch
as a combination of Note messages and Pitch Bend
messages. This means that if only the Note mes-
sages are examined on the sequencer’s microscope
(event list) screen, the on-screen information may
differ from what is actually performed.
→ If continuous pitch change is not required, you
can create data that is displayed more faithfully
by setting the sending Bend Range to “0.”
