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 charac-
ters described in
Table 1: Special characters used in the message en-
try field . 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 .
Min Value Lower limit of the data value
Max Value Upper limit of the data value

character
Explanation Details
DT Data insertion location
SS
Beginning of check-
sum calculation
If you use the automatic checksum calculation function, use
this special character to specify the point at which checksum
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 check-
sum 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 val-
ue 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 PCR 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 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 PCR 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 the range of the data itself (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.”
