■General

DR-670 can do one-way communications to send and receive parameters for songs, user patterns, user drum kits, and other memorized setting data. Model ID included in the exclusive message should be 00H 41H. The device ID code should be “DEV ID” value in MIDI mode, that is System Exclusive Device ID. Note that the actual value that set in device ID field is smaller by one than the value set as “DEV ID” in MIDI mode.

+——————+——————++——————+——————++——————+——————++——————+——————+ | D | H || D | H || D | H || D | H | +——————+——————++——————+——————++——————+——————++——————+——————+ | 0 | 00H || 32 | 20H || 64 | 40H || 96 | 60H | | 1 | 01H || 33 | 21H || 65 | 41H || 97 | 61H | | 2 | 02H || 34 | 22H || 66 | 42H || 98 | 62H | | 3 | 03H || 35 | 23H || 67 | 43H || 99 | 63H | | 4 | 04H || 36 | 24H || 68 | 44H || 100 | 64H | | 5 | 05H || 37 | 25H || 69 | 45H || 101 | 65H | | 6 | 06H || 38 | 26H || 70 | 46H || 102 | 66H | | 7 | 07H || 39 | 27H || 71 | 47H || 103 | 67H | | 8 | 08H || 40 | 28H || 72 | 48H || 104 | 68H | | 9 | 09H || 41 | 29H || 73 | 49H || 105 | 69H | | 10 | 0AH || 42 | 2AH || 74 | 4AH || 106 | 6AH | | 11 | 0BH || 43 | 2BH || 75 | 4BH || 107 | 6BH | | 12 | 0CH || 44 | 2CH || 76 | 4CH || 108 | 6CH | | 13 | 0DH || 45 | 2DH || 77 | 4DH || 109 | 6DH | | 14 | 0EH || 46 | 2EH || 78 | 4EH || 110 | 6EH | | 15 | 0FH || 47 | 2FH || 79 | 4FH || 111 | 6FH | | 16 | 10H || 48 | 30H || 80 | 50H || 112 | 70H | | 17 | 11H || 49 | 31H || 81 | 51H || 113 | 71H | | 18 | 12H || 50 | 32H || 82 | 52H || 114 | 72H | | 19 | 13H || 51 | 33H || 83 | 53H || 115 | 73H | | 20 | 14H || 52 | 34H || 84 | 54H || 116 | 74H | | 21 | 15H || 53 | 35H || 85 | 55H || 117 | 75H | | 22 | 16H || 54 | 36H || 86 | 56H || 118 | 76H | | 23 | 17H || 55 | 37H || 87 | 57H || 119 | 77H | | 24 | 18H || 56 | 38H || 88 | 58H || 120 | 78H | | 25 | 19H || 57 | 39H || 89 | 59H || 121 | 79H | | 26 | 1AH || 58 | 3AH || 90 | 5AH || 122 | 7AH | | 27 | 1BH || 59 | 3BH || 91 | 5BH || 123 | 7BH | | 28 | 1CH || 60 | 3CH || 92 | 5CH || 124 | 7CH | | 29 | 1DH || 61 | 3DH || 93 | 5DH || 125 | 7DH | | 30 | 1EH || 62 | 3EH || 94 | 5EH || 126 | 7EH | | 31 | 1FH || 63 | 3FH || 95 | 5FH || 127 | 7FH | +——————+——————++——————+——————++——————+——————++——————+——————+

D: decimal H: hexadecimal

* Decimal expressions such as used for MIDI channel, Program Change, and Device ID

will be the value 1 greater than the decimal value given in the above table.

* Since each MIDI byte carries seven significant data bits, each byte can express a

maximum of 128 different values. Data for which higher resolution is required must be transmitted using two or more bytes. For example data indicated as a two-byte value of aa bbH would have a value of aa x 128 + bb.

What is the decimal equivalent of 5AH? From the above table, 5AH = 90.

What is the decimal equivalent of the 7-bit hexadecimal values 12 34H? From the above table, 12H = 18 and 34H = 52 Thus, 18 x 128 + 52 = 2356

(“H” follows hexadecimal value)

❍Examples of actual MIDI messages

<Example> C9 49

CnH is the Program Change status and n is the MIDI channel number. Since 9H = 9 and 49H = 73, it is a Program Change message for MIDI CH = 10 and Program number = 74.

❍Examples of exclusive messages and calculating the checksum

Roland exclusive messages (RQ1, DT1) are transmitted with a checksum at the end of the data (before F7H) to check that the data was received correctly. The value of the checksum is determined by the address and data (or size) of the exclusive message.

❍How to calculate the checksum

The checksum consists of a value whose lower seven bits are zero when the address, size and checksum itself are added. The following formula shows how to calculate the checksum when the exclusive message to be transmitted has an address for aa bb cc ddH, and data or size for ee ffH.

aa + bb + cc + dd + ee + ff = total total / 128 = quotient ... remainder 128 - remainder = checksum

Checksum is zero if the remainder is zero.

<Example> Request to transfer the drum kits data

See the Parameter Address Map address : 30 00 00 00 00H size : can be any values (now using 00 00 00 00 00H)

F0 41 10 00 41 11 30 00 00 00 00 00 00 00 00 00 ?? F7 (1) (2) (3) (4) (5) address size checksum (6)

(1) Exclusive status (2) ID number (Roland) (3) Device ID (17) (4) Model ID (DR-670) (5) Command ID (RQ1) (6) End of Exclusive

Next, we calculate the checksum.

30H + 00H + 00H + 00H + 00H + 00H + 00H + 00H + 00H + 00H = 48 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 = 48 (sum)

48 (total) / 128 = 0 (quotient) ... 48 (remainder) checksum = 128 - 48 (remainder) = 80 = 50H

This means that the message transmitted will be F0 41 10 00 41 11 30 00 00 00 00 00 00 00 00 00 50 F7.
