When using acomputer for DW-6000 control and commu-

nications, asystem exclusive message and the following data

types are employed.

(DATA DUMP)

:Identifies the equipment. Sent upon

receiving aDEVICE ID REQUEST.

:Sent in response to aWRITE RE-

QUEST, this indicates that the PRO-

GRAM WRITE task has been success-

fully completed.

:Sent in response to aWRITE RE-

QUEST, this means that the synth is

set to the WRITE DISABLE mode so

The above examples require that the DW-6000 and com-

puter interface be connected via their respective MIDI IN

and MIDI OUT Jacks as shown here.

The above data types are used for communication in the

following ways.

(1)

To find the ID number for equipment connected to the

computer.
