F0 41 10 00 0A 12 01 00 02 32
(1) (2) (3) (4) (5) address
(1) Exclusive status (2) ID number (Roland)
(4) Model ID (TD-10) (5) Command ID (DT1)
Next we calculate the checksum.
01H + 00H + 02H + 32H + 05H = 1 + 0 + 2 + 50 + 5= 58 (sum)
58 (sum)/128 = 0 (quotient) ... 58 (remainder)
checksum = 128 - 58 (remainder) = 70 = 46H
This means that F0 41 10 00 0A 12 01 00 02 32 05 46 F7 is the message we transmit.
<Example 2> Requesting transmission of compressor swich of snare
drum in drum kit 1.
According to the "Parameter Address Map",the Drumkit No.1 has an address of 01 00 00
00H, Trigger 2 has a offset address of 02 00H and Compressor switch has a offset address
of 20H. Thus,

Since Size = 00 00 00 01H,
F0 41 10 00 0A 11 01 00 02 20
(1) (2) (3) (4) (5) address
(1) Exclusive status (2) ID number (Roland)
(4) Model ID (TD-10) (5) Command ID (RQ1)
Next we calculate the checksum.
01H + 00H + 02H + 20H + 00H + 00H +00H + 01H = 1 + 0 + 2 + 32 + 0 + 0 + 0 + 1 = 36 (sum)
36 (sum) / 128 = 0 (quotient) ... 15 (remainder)
checksum = 128 - 36 (remainder) = = 92 = 5CH
This means that F0 41 10 00 0A 11 01 00 02 20 00 00 00 01 5C F7 is the message we transmit.
