ii = ID number: An ID number (manufacturer ID) to indicate the manufacturer
whose Exclusive message this is. Roland’s manufacturer ID is
41H.
ID numbers 7EH and 7FH are extensions of the MIDI standard;
Universal Non-realtime Messages (7EH) and Universal Realtime
Messages (7FH).

Of the System Exclusive messages received by this device, the Universal Nonrealtime messages and the Universal Realtime messages and the Data Request (RQ1)
messages and the Data Set (DT1) messages will be set automatically.

* The amount of data that can be transmitted at one time depends on the type of
data, and data will be transmitted from the specied starting address and size.
Refer to the address and size given in “Parameter Address Map”.
* Data larger than 256 bytes will be divided into packets of 256 bytes or less, and
each packet will be sent at an interval of about 20 ms.
* When this message is received, Identity Reply message will be transmitted.
7Data Transmission
This instrument can use exclusive messages to exchange many varieties of internal
settings with other devices.
The model ID of the exclusive messages used by this instrument is 00H 00H 7BH.
6 Data Request 1 RQ1 (11H)
This message requests the other device to transmit data. The address and size
indicate the type and amount of data that is requested.
When a Data Request message is received, if the device is in a state in which it is able
to transmit data, and if the address and size are appropriate, the requested data is
transmitted as a Data Set 1 (DT1) message. If the conditions are not met, nothing is
transmitted.

3. Parameter Address Map
* Transmission of “#” marked address is divided to some packets. For example, ABH in
hexadecimal notation will be divided to 0AH and 0BH, and is sent/received in this
order.
* “<*>” marked address or parameters are ignored when the VT-4 received them.

9 Decimal and Hexadecimal Table
(An “H” is appended to the end of numbers in hexadecimal notation.)
In MIDI documentation, data values and addresses/sizes of Exclusive messages, etc.
are expressed as hexadecimal values for each 7 bits.
The following table shows how these correspond to decimal numbers.

D: decimal
H: hexadecimal
* Decimal values such as MIDI channel, bank select, and program change are listed as
one greater than the values given in the above table.
* A 7-bit byte can express data in the range of 128 steps. For data where greater
precision is required, we must use two or more bytes. For example, two
hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of
aa x 128+bb.
* In the case of values which have a +/- sign, 00H = -64, 40H = +/-0, and 7FH = +63,
so that the decimal expression would be 64 less than the value given in the above
chart. In the case of two types, 00 00H = -8192, 40 00H = +/-0, and 7F 7FH = +8191.
For example, if aa bbH were expressed as decimal, this would be aa bbH - 40 00H =
aa x 128+bb - 64 x 128.
* Data marked “Use nibbled data” is expressed in hexadecimal in 4-bit units. A value
expressed as a 2-byte nibble 0a 0bH has the value of a x 16+b.
<Example 1> What is the decimal expression of 5AH?
From the preceding table, 5AH = 90
<Example 2> What is the decimal expression of the value 12 34H given as
hexadecimal for each 7 bits?
From the preceding table, since 12H = 18 and 34H = 52
18 x 128+52 = 2356
9 Example of an Exclusive Message and Calculating a
Checksum
Roland Exclusive messages (RQ1, DT1) are transmitted with a checksum at the end
(before F7) to make sure that the message was correctly received. The value of
the checksum is determined by the address and data (or size) of the transmitted
Exclusive message.
7How to calculate the checksum
(hexadecimal numbers are indicated by “H”)
The checksum is a value derived by adding the address, size, and checksum itself and
inverting the lower 7 bits.
Here’s an example of how the checksum is calculated. We will assume that in the
Exclusive message we are transmitting, the address is aa bb cc ddH and the data or
size is ee H.
aa + bb + cc + dd + ee + = sum
sum ÷ 128 = quotient ... remainder
128 - remainder = checksum
<Example 1> Set the PITCH parameter to 255(FFH)
According to the “Parameter Address Map”, the address is 10 00 00 09H.
So the system exclusive message should be sent is;
F0 41 10 00 00 00 51 12 10 00 00 09 0F 0F ?? F7
(1) (2) (3) (4) (5) address data checksum (6)
(1) Exclusive Status (2) ID (Roland) (3) Device ID (17)
(4) Model ID (VT-4) (5) Command ID (DT1) (6) End of Exclusive
Then calculate the checksum.
10H + 00H + 00H + 09H + 0FH + 0FH = 16 + 0 + 0 + 9 + 15 + 15 = 55 (sum)
55 (sum) ÷ 128 = 0 (quotient) ... 55 (remainder)
checksum = 128 - 55 (remainder) = 73 = 49H
This means that F0 41 10 00 00 00 51 12 10 00 00 09 0F 0F 49 F7 is the message
should be sent.
<Example 2> Request Value of the Pitch (RQ1)
According to the “Parameter Address Map”, the address is 10 00 00 09H.
So the system exclusive message should be sent is;
F0 41 10 00 00 00 51 11 10 00 00 09 00 00 00 02 ?? F7
(1) (2) (3) (4) (5) address data checksum (6)
(1) Exclusive Status (2) ID (Roland) (3) Device ID (17)
(4) Model ID (VT-4) (5) Command ID (RQ1) (6) End of Exclusive
Then calculate the checksum.
10H + 00H + 00H + 09H+ 00H + 00H + 00H + 02H =
16 + 0 + 0 + 9 + 0 + 0 + 0 + 2 = 27 (sum)
27 (sum) ÷ 128 = 0 (quotient) ... 27 (remainder)
checksum = 128 - 27 (remainder) = 101 = 65H
This means that F0 41 10 00 00 00 51 11 10 00 00 09 02 65 F7 is the message should
be sent.
<Example 3> What is the decimal expression of the nibbled value 0A 03 09 0D?
From the preceding table, since 0AH = 10, 03H = 3, 09H = 9, 0DH = 13
((10 x 16+3) x 16+9) x 16+13 = 41885
<Example 4> What is the nibbled expression of the decimal value 1258?
16 ) 1258
16 ) 78 ...10
16 ) 4 ...14
0 ... 4
Since from the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH, the result is: 00
04 0E 0AH.
