Boss Audio Systems owner manual Operations Using Midi, Operating From the GS-10

Chapter 8 Using the GS-10 with External MIDI Devices Connected

The GS-10’s MIDI operations are altered when the GS-10 and the computer are connected via USB.

Also refer to “Chapter 9 Using USB to Connect a Computer” (p. 78) when making these connections.

Operations Using MIDI

You can perform the following operations using MIDI with the GS-10.

*The use of MIDI requires that the MIDI channels of the connected devices match. If the MIDI channel settings are not correct, the GS-10 will be unable to exchange data with other MIDI devices.

Operating From the GS-10

Outputting Program Change Messages

When a patch is selected on the GS-10, 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 external devices connected to the EXP PEDAL/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.

Transmitting Data

You can use Exclusive messages to transmit the settings for effect sounds and other content stored in the GS-10 to other MIDI devices. For example, you can provide another GS-10 with the same settings, and save effect sound settings to a sequencer or other device.

Remotely Controlling the GS-10 Using an External MIDI Device

Switching Patch Numbers

When the GS-10 receive 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 GS-10’s patches using the Program Change Map (p. 73). 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 guitar 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 GS-10 patches are to be switched.

Receiving Control Change Messages

You can control specified parameters during a performance by having the GS-10 receive Control Change messages.

Parameters to be controlled are set with Assign (p. 60).

Receiving Data

The GS-10 can receive data transmitted from another GS-10, as well as data that’s been stored on a sequencer.
