ceiver is set to the same channellhal is being used for
transmission.

2. MIDI Messages Recognized by the GP·
16
In order to convey the great variety of expression pos~
sible with music, MIDI has been provided with a large
range of data types (messages).
Program Change Messages
These messages are used mainly lor making changes to
another sound. Sounds are changed uSing Program
Change Numbers, from 1 to 128. Patch changes on the
GP·16 correspond with Program Change Numbers as
follows;

Control Change Messages
Control Changes messages are used to enhance the ex·
preSSIvity of a performance. Each function is identified
by a Control Change Number, and the functions avail-
able for control will vary depending on the instrument.
On the GP·16, functions equivalent to "EXP(1)", "EXP2",
and "Control Pedal", for a foot controller connected to the
GP-16 can be controlled lrom another device.
Exclusive Messages
Exclusive Messages handle information such as that re-
lated to a device's unIque tones. Generally, such
mes~
sages can be exchanged only between devices of the
same model and by the same manufacturer. Exclusive
Messages can be employed instead of Program Change
Numbers to save Patch se"ings to a sequencer, or used
lor transferrrng Patch settings to another GP-16.
Whenever Exclusive Messages are to be used lor com-
munication, both musical instruments need to be set to
the same Unit Number. On the GP·16 fhe Unit Number
corresponds to Ihe MIDI Channel's number.
If a sequencer capable of handling Exclusive Messages is
used, instead of Program Change Numbers, temporary
data can be transmitted. and lone changes can be made.
