Chapter 9 Connecting to External Sound Generators and Sequencers
About “Local Control Off”
While the GR-33’s internal sound generator and guitar 
controller are connected together, it is set to “Local On.” In 
contrast to this, “Local Off” is when the GR-33’s internal 
sound generator and guitar controller are separated, and 
only MIDI message from a sequencer is played. Also, guitar 
performance message is output only from MIDI OUT.
fig.9-14
Collisions of performance data from both the guitar and the 
sequencer that occur at times such as when “soft thru” is 
enabled can be prevented by turning off local control.
To turn off local control, switch the power off and back on 
while holding down the [PLAY] button. (The setting for 
turning off local control is canceled when the power is 
switched on again, and is not saved in memory.)
* The detailed behavior of internal functions differs depending 
on whether local control is on or off. Local control is normally 
on, but you should be sure to switch off local control when a 
loop connection with external equipment is used.
Making a MIDI loop connection with local control remaining 
on may result in problems or faulty operation, such as failure 
to recognize switch operations.
* Set MIDI [PC], MIDI [CC0], and MIDI [CC32] only when a 
MIDI loop connection is not being used.
Creating Realistic Plucked String 
Instrument Sounds (Data)
Using the GR-33 to input parts for guitars and similar string 
instruments, including harps, koto, and others, makes it 
possible to achieve voicing and an expressive feeling of 
dispersions for separately plucked strings that cannot be 
reproduced with keyboard input. When doing this, however, 
attention should be given to the following points.
Make sure that no Quantize function (a function which 
forces data with loose input timing to conform to precise 
timing as eighth notes, sixteenth notes, or the like) has 
been enabled for input-data timing on the sequencer.
When performing post-recording operation on the 
sequencer to shift the position of data, make sure that 
Bend messages are also shifted along with Note 
messages, so as not to destroy the correspondences 
between the two types of messages.
Also, those special changes in pitch that can only be 
produced by a guitar synthesizer (such as using the tremolo 
bar and harmonized bending) can also be input to the 
sequencer and played by means of transmission in the Mono 
mode, which uses one MIDI channel for each string.
Recording Arpeggiator and 
Harmonist Performances
Recording Arpeggiator Effects on a Sequencer
Example 1:
Arpeggiate the notes of the external MIDI sound generator, 
and record the results
Set the EFFECTS “HAR/ARP SELECT” setting in the Patch 
Edit mode to “Arpeggio Ext,” then take the steps 1, 2 and 4 of 
“Input Procedures and Settings for Each Device” on p. 93. 
(Please don’t take step 3.) After taking step 4, play the guitar 
and make sure that the external MIDI sound generator is 
arpeggiated.  Then, go to step 5 to record it.
Example 2:
Arpeggiate the GR-33’s first and second tones, and record the 
results
Set the EFFECTS “HAR/ARP SELECT” setting in the Patch 
Edit mode to “Arpeggio 1st,” “Arpeggio 2nd,” or “Arpeggio 
1&2,” and carry out recording. (Arpeggios are played while 
recording, but only the original guitar-performance 
information—and not arpeggio information itself—is 
recorded on the sequencer.) If the same patch is used during 
playback, performance information is received from MIDI IN 
and the GR-33 rebuilds the arpeggios.
* The setting “Arpeggio All” is not suitable for “HAR/ARP 
SELECT” when a sequencer and the GR-33 are connected by a 
MIDI cable (local control off).
