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
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.
