Chapter 6 Using the GT-10B with
External MIDI Devices Connected
You can perform the following operations using MIDI with the
GT-10B.
The use of MIDI requires that the MIDI channels of the connected devices
match. If the MIDI channel settings are not correct, the GT-10B will be unable
to exchange data with other MIDI devices.
Outputting Program Change Messages
When a patch is selected on the GT-10B, 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.

Outputting Control Change Messages
Data describing the actions of the CTL pedal, EXP Pedal, EXP
PEDAL SW, and external devices connected to the EXP PEDAL
2/CTL 3, 4 jack are output as Control Change messages. Such
messages can be used to (among other things) manipulate the
parameters of an external MIDI device.
Transmitting Data
You can use Exclusive messages to transmit the settings for
effect sounds and other content stored in the GT-10B to other
MIDI devices. For example, you can provide another GT-10B
with the same settings, and save effect sound settings to a
sequencer or other device.
Switching Patch Numbers
When the GT-10B receives Program Change messages from the
external MIDI device, its patches are simultaneously switched.
You can set up the correspondence between MIDI Program Change messages
and the GT-10B’s patches using the Program Change Map (p. 88). You may
need to work on these correspondences when you want to line up some effects
in combination 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-10B patches are to be switched.
Receiving Control Change Messages
You can control specified parameters during a performance by having the GT-
10B receive Control Change messages. Parameters to be controlled are set with
“Manual Settings” (p. 52).
Receiving Data
The GT-10B can receive data transmitted from another GT-10B,
as well as data that’s been stored on a sequencer.

Exchanging MIDI Messages between the Computer and the GT-10B
If the Driver Mode parameter set to the Advanced (p. 95), and you connect the GT-10B to your PC/Mac by a USB cable, you
can transfer MIDI message bidirectionally via USB.
Set your computer MIDI input and output ports to “GT-10B.”
However, MIDI message transfer via GT-10B’s MIDI connectors become inactivated in this situation.
