Boss Audio Systems Using Midi, What Can You Do with MIDI?, Operating From the GT-6B

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.

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.
