System messages

System messages include exclusive messages, messages used for synchronization, and messages used to keep a MIDI system running correctly.

Exclusive messages

Exclusive messages handle information related to a unit’s own unique sounds, or other device-specific information. Generally, such messages can only be exchanged between devices of the same model by the same manufacturer.

Exclusive messages can be employed to save the settings for effects programs into a sequencer, or for transferring such data to another GT-6B.

The two instruments must be set to the same device ID numbers when exchanging SysEx messages.

About the MIDI implementation

MIDI allows a variety of messages to be exchanged between instruments, but it is not necessarily the case that all types of message can be exchanged between any two MIDI devices.

Two devices can communicate only if they both use the types of messages that they have in common.

Thus, every owner’s manual for a MIDI device includes a

“MIDI Implementation Chart.” This chart shows the types of message that the device is able to transmit and receive. By comparing the MIDI implementation charts of two devices, you can tell at a glance which messages they will be able to exchange. Since the charts are always of a uniform size, you can simply place the two charts side by side.

A separate publication titled “MIDI Implementation” is also available. It provides complete details concerning the way MIDI has been implemented on this unit. If you should require this publication (such as when you intend to carry out byte-level programming), please contact the nearest Roland Service Center or authorized Roland distributor.
