Value Notation

Hexadecimal Notation

MIDI implementation sometimes requires that data be expressed in hexadecimal format. Hexadecimal
values are indicated by the letter “H” after the value. The hexadecimal equivalents of decimal values 10
through 15 are expressed as the letters A through F.

The table below shows the hexadecimal equivalents for decimal values 0 through 127, which are often

used in MIDI messages.

Binary Notation

When a MIDI implementation data value is expressed in binary, the letter “B” (for “binary”) is affixed
at the end of the value. The table below shows the binary equivalents for the decimal values 0 through
127, which are often used for settings.
