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.
88
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."
