The data format name ending in bytes 14 and 15 specifies the type of bulk data, as follows.
mm Data type
“SY” System parameter bulk dump
“PG” Program bulk dump
“SB” Sample bank bulk dump
“SP” Sample bulk dump
“WD” Wave data bulk dump
“SQ” Sequence bulk dump
“OL” Object list bulk dump
Note) mm is ASCII code
object name is a 16-character name for each object. Program object names are the pro-
gram number of each program (example: “001 “). System parameters and object lists
are always “SystemParameters” and “Object List “, respectively.
The data section is divided into byte 1, which is the upper nibble, and byte 2, which is the
lower nibble. See chart 1 for details.
The byte is all data between the byte count and checksum.
The checksum is the exclusive-or value of all bytes between the byte count and checksum.
For each bulk dump, the number of transmitted bytes between the byte count and checksum
is less than 4096. When the amount of data to be transmitted is greater than this, it is divided
into 4096 byte blocks transmitted between byte count and checksum data. F7 is transmitted
when all data has been transmitted. From the second block onward the header from byte
6 to byte 31 is not included.
5.2. Dump request
Bulk dump transmission is performed when a dump request is received.

The data format name ending in bytes 12 and 13 specifies the type of transmitted data, as
follows.
mm Data type
“SY” System parameter bulk dump
“PG” Program bulk dump
“SB” Sample bank bulk dump
“SP” Sample bulk dump
“WD” Wave data bulk dump
“SQ” Sequence bulk dump
“OL” Object list bulk dump
Note) mm is ASCII code
object name is a 16-character name for each object. Program object names are the pro-
gram number of each program (example: “001 “). System parameters and object lists
do not have an object name, and are recognized by their data format name.
5.3. Parameter change
For changes to the value of an object parameter, first the object is selected via parameter
change (object select) reception, then the value is changed via parameter change (object
edit) reception. The object selection remains effective until the next object select is re-
ceived, thus a number of changes to the value of the same object can be carried through
successive object edit reception.
Transmitted when a parameter value request is received.
If the sample contains a release loop, this message is transmitted after the sample dump.
Alternatively, this message is transmitted in reply to a Loop Point Request message.

Transmission occurs when a bulk dump transmit command is executed or a dump request
is received.
This message can be received if bulk protect is off.
