Chapter 11 Appendices
Pitch doesn’t change smoothly
● Is data being sent in the Poly mode? When
transmitting in the Poly mode, pitch changes during
chord performances are in semitone steps (p. 88).
→ Play with single notes, or use the Mono mode to send
data.
● Is the Bend Data Thin function (p. 95) in use?
→ Do not use the Bend Data Thin function when it is not
needed.
● Is SYSTEM “BEND RANGE” set to “1” or “2”?
→ When matching with sending and receiving, use as large
a value as possible (p. 86).
● If SYSTEM “BEND RANGE” has been set to “0,” the
pitch will change in semitone.
→ Change the setting to a preferable value (p. 86).
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-33 transmits pitch as a
combination of Note messages and Pitch Bend
messages. This means that if only the Note messages
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.” (p. 88)
Others
The volume level of the instrument
connected to RETURN jack is too low.
● Could you be using a connection cable that contains a
resistor?
→ Use a connection cable that does not contain a resistor.
Error Messages
Battery Low!
Cause: The internal backup battery (the battery which
maintains the data in the user memory) is
running down.
Solution: Contact your dealer or a nearby Roland service
center to have the battery replaced.
Memory Damaged!
Press WRITE
Cause: The contents of internal memory has been lost
due to the backup battery having run down or to
some malfunction.
Solution: Press [WRITE] to execute Factory Reset. If this
does not resolve the problem, contact a nearby
Roland service center.
MIDI
Off Line!
Cause:
There is a problem with the MIDI cable connection.
Solution: Check that the MIDI cable has not been
disconnected or broken.
MIDI
Buffer Full!
Cause: More MIDI data was received at once than could
be handled by the GR-33.
Solution: Reduce the amount of MIDI data that is being
received by the GR-33.
Wrong Address!
Cause: The System Exclusive address value that was
received is incorrect.
Solution: Correct the address value.
Checksum Error!
Cause: The System Exclusive checksum value that was
received is incorrect.
Solution: Correct the checksum value.
