<Example 1>
Specifying a TUNING of +5 for the instrument assigned to the SNARE head of drum kit number 1
From the "parameter address map," the start address for drum kit number 1 is 03 00 00 00H, and the VEdit parameter of the instrument
that is assigned to the SNARE head has an offset address of 01 01 00H, and the offset address of TUNING is 00 01H; thus, the address
is
03 00 00 00H
01 01 00H
+) 00 01H
----------------
03 01 01 01H
Since +5 is the parameter value 00 00 00 05H
F0 41 10 00 00 00 4B 12 03 01 01 01 00 05 ?? F7
(1) (2) (3) (4) (5) address data checksum (6)
(1) Exclusive Status (2) ID (Roland)
(3) Device ID (17) (4) Model ID (TD-17)
(5) Command ID (DT1) (6) EOX
Then calculate the checksum.
03H + 01H + 01H + 01H + 00H + 05H = 3 + 1 + 1 + 1 + 0 + 5 = 11 (sum)
11 (sum) ÷ 128 = 0 (quotient) … 11 (remainder) checksum = 128 - 11 (remainder) = 117 = 75H
This means that F0 41 10 00 00 00 4B 12 03 01 01 01 00 00 00 05 75 F7 is the message
should be sent.
<Example 2>
Requesting transmission of the pad EQ switch for the SNARE of drum kit number 1
“Parameter address map” indicates that the start address of drum kit 1 is 03 00 00 00H, the offset address of the SNARE pad
parameters is 00 21 00H, and the offset
address of the pad EQ switch is00 05H; therefore, the address is
03 00 00 00H
00 21 00H
+) 00 05H
----------------
03 00 21 05H
Since the size is 00 00 00 01H
F0 41 10 00 00 00 4B 11 03 00 21 05 00 00 00 01 ?? F7
(1) (2) (3) (4) (5) address size checksum (6)
(1) Exclusive Status (2) ID (Roland)
(3) Device ID (17) (4) Model ID (TD-17)
(5) Command ID (DT1) (6) EOX
Then calculate the checksum.
03H + 00H + 21H + 05H + 00H + 00H +00H + 01H = 3 + 0 + 33 + 5 + 0 + 0 + 0 + 1 = 42 (sum)
42 (sum) ÷ 128=0 (quotient) … 42 (remainder) = 128 - 42 (remainder) = 86 = 56H
This means that F0 41 10 00 00 00 4B 11 03 00 21 05 00 00 00 01 56 F7 is the message should be sent.
