■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.

Decimal values such as MIDI channel, bank select, and program change are listed as one
greater than the values given in the above table.
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.

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.
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
18 x 128+52 = 2356
[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

■Examples of actual MIDI messages
[Example 1] 92 3E 5F
9n is the Note-on status, and n is the MIDI channel number. Since 2H = 2, 3EH = 62, and
5FH = 95, this is a Note-on message with MIDI CH = 3, note number 62 (note name is D4),
and velocity 95.
5FH = 95, this is a Note-on message with MIDI CH = 3, note number 62 (note name is D4),
and velocity 95.
[Example 2] CE 49
CnH is the Program Change status, and n is the MIDI channel number. Since EH = 14 and
49H = 73, this is a Program Change message with MIDI CH = 15, program number 74 (Flute
in GS).
49H = 73, this is a Program Change message with MIDI CH = 15, program number 74 (Flute
in GS).
[Example 3] EA 00 28
EnH is the Pitch Bend Change status, and n is the MIDI channel number. The 2nd byte (00H
= 0) is the LSB and the 3rd byte (28H = 40) is the MSB, but Pitch Bend Value is a signed
number in which 40 00H (= 64 x 12+80 = 8192) is 0, so this Pitch Bend Value is 28 00H - 40
00H = 40 x 12+80 - (64 x 12+80) = 5120 - 8192 = -3072.
= 0) is the LSB and the 3rd byte (28H = 40) is the MSB, but Pitch Bend Value is a signed
number in which 40 00H (= 64 x 12+80 = 8192) is 0, so this Pitch Bend Value is 28 00H - 40
00H = 40 x 12+80 - (64 x 12+80) = 5120 - 8192 = -3072.
If the Pitch Bend Sensitivity is set to 2 semitones, -8192 (00 00H) will cause the pitch to
change by -200 cents, so in this case -200 x (-3072) ÷ (-8192) = -75 cents of Pitch Bend is being
applied to MIDI channel 11.
change by -200 cents, so in this case -200 x (-3072) ÷ (-8192) = -75 cents of Pitch Bend is being
applied to MIDI channel 11.
[Example 4] B3 64 00 65 00 06 0C 26 00 64 7F 65 7F
BnH is the Control Change status, and n is the MIDI channel number. For Control Changes,
the 2nd byte is the control number, and the 3rd byte is the value. In a case in which two or
more consecutive messages have the same status, MIDI has a provision called “running
status” which allows the status byte of the second and following messages to be omitted.
Thus, the above messages have the following meaning.
the 2nd byte is the control number, and the 3rd byte is the value. In a case in which two or
more consecutive messages have the same status, MIDI has a provision called “running

Thus, the above messages have the following meaning.
