@ Receiving Exclusive Data
As listed in the "MIDI Implementation" ( p. 36), the address of
MIDI exclusive data (GS format) is defined in units of 16 Parts.
In other words, starting from address 40 00 00 are the parameters
for 16 Parts.
The M-GS64 has data for another 16 Parts, making a total of 32
Parts. For this reason, the M-GS$64's MIDI exclusive data format
extends the addressing, and places the remaining 16 Parts at
starting address 50 00 00.
In the same way as with channel messages, exclusive data
received at MIDI IN A is passed to Group A Parts, and exclusive
data received at MIDI IN B is passed to Group B Parts.
In other words, exclusive data for the 32 Parts is received using
two MIDI IN connectors. If this is done, each MIDI IN receives
exclusive data for the relevant 16 Parts, so it is not necessary to
split up the data into addresses 40 00 00 and 50 00 00.

However, it is also possible for the M-GS64 to receive exclusive
data for all 32 Parts at a single MIDI IN. In this case it is neces-
sary to use address 50 CO 00. For example, the data at starting
address 40 00 00 will be passed to Group A Parts, and the data at
starting address 50 00 00 received at the same MIDI IN will be
passed to Group B Parts. In other words, using starting address
50 00 00 means that the data will be passed to the Parts of the
Group other than that which would normally be used for the
MIDI IN at which the data was received.

Only in the case of Exclusive data, the System parameter Input
Mode ( p. 16) has no effect on the way in which data is passed
from the two MIDI IN connectors to the Parts.
@ Transmitting Exclusive Data
Since the M-GS64 has only one MIDI] OUT, the exclusive data
transmitted is sent using the two address areas of 40 00 00 and 50
00 00. User sound data is located at starting areas of 2000 00.
* Be aware that exclusive data will be not transmitted from the
MIDI OUT connector if the MIDI OUT/THRU select ( p. 18) is
set to THRU.
