The DW-8000 can use these system exclusive messages
to communicate with acomputer equipped with a
MIDI interface. (A program to process the exclusive
messages is required.)
•Connecting acomputer
Because each exclusive message for the DW-8000 is speci-
fied with achannel designated by parameter 84, the corre-
sponding channel must be used for message transmission
from acomputer to the DW-8000. Amessage sent using the
incorrect channel will be ignored, regardless of OMNI
mode being ON or OFF.
These channels are used to effectively that timbre control
could be done independently for each DW-8000 in asystem
using two or more DW-8000s.
