Chapter 10 Using MIDI
What Can You Do with MIDI?
You can perform the following operations using MIDI with
the GT-6B.
* The use of MIDI requires that the MIDI channels of the
connected devices match. If the MIDI channel settings are not
correct, the GT-6B will be unable to exchange data with other
MIDI devices.
Operating From the GT-6B
Outputting Program Change Messages
When a patch is selected on the GT-6B, a Program Change
message corresponding to the patch number is transmitted
simultaneously. The external MIDI device then switches its
settings according to the Program Change message it receives.
fig.10-01
Outputting Control Change Messages
Data describing the actions of the CTL pedal, expression
pedal, expression pedal switch, and external devices
connected to the SUB EXP PEDAL/SUB CTL 1,2 jack are
output as Control Change messages. Such messages can be
used to (among other things) manipulate the parameters of
an external MIDI device.
MIDI Start/Stop, MMC Play/Stop
MIDI Start/Stop or MMC Start/Stop messages are output
when the CTL pedal, the expression pedal, the expression
pedal switch, or the external device connected to the SUB
EXP PEDAL/SUB CTL 1,2 jack is operated, allowing you to
control the performance of the external MIDI device.
* For more on how to make the settings, refer to p. 48 and 63.
Transmitting Data
You can use Exclusive messages to transmit the settings for
effect sounds and other content stored in the GT-6B to other
MIDI devices. For example, you can provide another GT-6B
with the same settings, and save effect sound settings to a
sequencer or other device.
Controlling the GT-6B Remotely From
an External MIDI Device
Switching Patch Numbers
When the GT-6B receives Program Change messages from
the external MIDI device, the corresponding patches are
switched simultaneously.
You can set the correspondence between MIDI Program
Change messages and the GT-6B’s patches using the
Program Change Map (p. 69). Make these settings when
you create correspondences for effect sounds with other
MIDI devices.
The connections shown in the figure below are for a
sequencer automatically performing the backing as a bass is
being played. The patches are switched automatically when
the program numbers corresponding to the patches are input
along with the performance data at the points where you
have determined the GT-6B patches are to be switched.

Receiving Control Change Messages
You can control specified parameters during a
performance through Control Change messages received
by the GT-6B. Parameters to be controlled are set with
Pedal Assign (p. 46).
Receiving Data
The GT-6B can receive data transmitted from another GT-6B,
as well as data that’s been stored on a sequencer.
