3. INTERFACE WITH PERSONAL COMPUTER
When using acomputer for DW-6000 control and commu-
nications, asystem exclusive message and the following data
types are employed.
Sending Receiving

(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
PROGRAM WRITE task cannot be
completed.
:In response to aDATA SAVE RE-
QUEST, this sends the data for the

:A request for the equipment's MIDI
identification number.
:Arequest for the DW-6000 to write
data for the present sound to program
memory.
:Arequest for the DW-6000 to send
data for the present sound.
:Used to change parameters of the cur-
rent sound.
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.

(2)
To edit sound data within the DW-6000.
