Item Content
Message entry field
You can enter a system exclusive message of up to twenty-four bytes.
Enter each byte as a hexadecimal value separated by a single-byte space.
The following limitations apply to the input.
* The message must begin with “F0” and end with “F7.”
* You cannot include more than one exclusive message.
* You cannot include messages other than an exclusive message.
You can enter variable data or a checksum using the special characters
described in “Table 1: Special characters used in the message entry field”
(p. 38). If you use the special character “DT,” use the Data Type field to
specify the type of data.
Data Type
If you’ve used the special character “DT” in the message entry field, use
this to specify the type of data to be inserted at that location. For the
types of data that can be specified, refer to “Table 2: Types of data you
can specify in the Data Type field” (p. 38).
Min Value Lower limit of the data value
Max Value Upper limit of the data value
Special
character
Explanation Details
DT Data insertion location The data specified by Data Type will be inserted.
SS
Beginning of checksum
calculation
If you use the automatic checksum calculation function, use
this special character to specify the point at which check-
sum calculation is to begin.
S1/S2
Checksum insertion
location and type
If you use the automatic checksum calculation function, use
this special character to specify the point at which the
checksum is to be inserted, and its type.
S1: The most common type, used by Roland and other man-
ufacturers.
S2: Choose this if a method other than S1 is used.
?n
Channel (? is any value
between 0–7)
If you want a channel number to be inserted in the exclusive
message, use this special character to specify its location
and the upper four bits (a fixed value of 0–7). The current
channel of the A-PRO will be inserted in the channel section.
?x
Block number (? is any
value between 0–7)
If you want a GS block number to be inserted in the exclu-
sive message, use this special character to specify its loca-
tion and the upper four bits (a fixed value of 0–7). The
current channel of the A-PRO will converted into the block
number and inserted.
Data type Data length Target of the specified Min Value / Max Value
DT0: 7-bit 1 byte Specifies a range from 0 to 127 (0–127)
DT1: 4-bit/4-bit 2 bytes
Specifies the range of the first byte (0–15)
* The second byte is fixed at 0–15
DT2: 7-bit/7-bit
(MSB/LSB)
2 bytes
Specifies the range of the MSB (0–127)
* The LSB is fixed at 0–127
DT3: 7-bit/7-bit
(LSB/MSB)
2 bytes
Specifies the range of the MSB (0–127)
* The LSB is fixed at 0–127
DT4: 4-bit/
4-bit/4-bit/4-bit
4 bytes
Specifies the range of change (0–255) between the negative di-
rection (Min) and the positive direction (Max), centered on 8000h.
Example of input
1. Enter the following in the message entry field.
F0 41 10 42 12 SS 40 1X 32 DT S1 F7
2. In the Data Type field, choose “DT0.” Specify the
Min Value as “0” and the Max Value as “127.”
F0 41 10 42 12 SS 40 1x 32 DATA SUM F7
Block number 1 byte
