Supplementary material Decimal/Hexadecimal table (Hexadecimal values are indicated by a following "H") MIDI uses 7-bit hexadecimal values to indicate data values and the address and size of exclusive messages. The following table shows the correspondence between decimal and hexadecimal numbers. +------------+------------++------------+------------++------------+------------++------------+------------+ |10 |16 ||10 |16 ||10 |16 ||10 |16 | +------------+------------++------------+------------++------------+------------++------------+------------+ | 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 | +------------+------------++------------+------------++------------+------------++------------+------------+ * * Decimal expressions such as used for MIDI channel, Bank Select, and Program Change will be the value 1 greater than the decimal value given in the above table. Since each MIDI byte carries 7 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 a value indicated as a two-byte value of aa bbH would have a value of aa x 128 + bb. How to calculate the checksum (Hexadecimal values are indicated by a "H") The checksum consists of a value whose lower 7 bits are 0 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 of aa bb cc ddH, and data or size of ee ffH. aa + bb + cc + dd + ee + ff = total total / 128 = quotient. . . remainder 128 - remainder = checksum Checksum is 0 if the remainder is 0. ASCII code table On the CN-20, the following ASCII code set is used for processing data such as the Song Name, Pattern Name, kit Name, TSC name, and Guitar Effect Name. [. . . ]
