Chapter 9 Connecting to External Sound Generators and Sequencers
“GUITAR,” a value of zero is sent to the external sound
generator on the Control Change message No. 7, and sound

the GK-2A volume or the expression pedal are sent, and
sound production is restarted.

Transmitting in Mono Mode or Poly Mode
Transmission in Mono or Poly mode, one or the other of

MIDI CHANNEL setting, differs as follows.
❍
Transmitting in Mono Mode
Number of channels used:
One channel per string is used. The number selected when
specifying the channel in the System mode is taken as the
start for automatically selecting six consecutive channels.
(For example, when “Mono 3” is selected, the six channels
from channel 3 to channel 8 are sequentially used for strings
1 through 6. This means that no channel from 12 to 16 can be
selected as the starting channel when transmitting in Mono
mode.)

Features:
Information on continuous pitch changes (MIDI Bend
messages) can be sent independently for each string. This
makes it possible to reproduce unique guitar techniques such
as tremolo bar usage and harmonized bending.

Features:
Only a single channel is used for all guitar parts, so the
number of MIDI channels used can be reduced. This enables
control even for sound generators which cannot receive
simultaneously on six channels.

However, it should be noted that when two or more strings
are playing, Bend messages are not sent and the pitch

perfectly in the synth sound.

Transmitting MIDI Messages from the GR-33
(MIDI [PC])
When the pedal or [VALUE] is used to change patches on the
GR-33, a Program Change (tone change) message is sent to
the external device from MIDI OUT. This can be used to
change tones on the external sound generator or to change
patches for guitar-sound effects.

The number of the Program Change message that is sent can

the time of purchase, Program Change numbers 1 through
