Part VIIIMIDI Implementation Notation34 Value Notation34.1 Hexadecimal NotationMIDI implementation sometimes requires that data be expressed in hexadecimal format. Hexadecimalvalues are indicated by the letter “H” after the value. The hexadecimal equivalents of decimal values 10through 15 are expressed as the letters A through F.The table below shows the hexadecimal equivalents for decimal values 0 through 127, which are oftenused in MIDI messages.Decimal Hexadecimal Decimal Hexadecimal Decimal Hexadecimal Decimal Hexadecimal0 00H 32 20H 64 40H 96 60H1 01H 33 21H 65 41H 97 61H2 02H 34 22H 66 42H 98 62H3 03H 35 23H 67 43H 99 63H4 04H 36 24H 68 44H 100 64H5 05H 37 25H 69 45H 101 65H6 06H 38 26H 70 46H 102 66H7 07H 39 27H 71 47H 103 67H8 08H 40 28H 72 48H 104 68H9 09H 41 29H 73 49H 105 69H10 0AH 42 2AH 74 4AH 106 6AH11 0BH 43 2BH 75 4BH 107 6BH12 0CH 44 2CH 76 4CH 108 6CH13 0DH 45 2DH 77 4DH 109 6DH14 0EH 46 2EH 78 4EH 110 6EH15 0FH 47 2FH 79 4FH 111 6FH16 10H 48 30H 80 50H 112 70H17 11H 49 31H 81 51H 113 71H18 12H 50 32H 82 52H 114 72H19 13H 51 33H 83 53H 115 73H20 14H 52 34H 84 54H 116 74H21 15H 53 35H 85 55H 117 75H22 16H 54 36H 86 56H 118 76H23 17H 55 37H 87 57H 119 77H24 18H 56 38H 88 58H 120 78H25 19H 57 39H 89 59H 121 79H26 1AH 58 3AH 90 5AH 122 7AH27 1BH 59 3BH 91 5BH 123 7BH28 1CH 60 3CH 92 5CH 124 7CH29 1DH 61 3DH 93 5DH 125 7DH30 1EH 62 3EH 94 5EH 126 7EH31 1FH 63 3FH 95 5FH 127 7FH34.2 Binary NotationWhen a MIDI implementation data value is expressed in binary, the letter “B” (for “binary”) is affixedat the end of the value. The table below shows the binary equivalents for the decimal values 0 through127, which are often used for settings.42
