CONTROL FREAK OVERVIEW OF THE MIDI MESSAGE FORMAT

Overview of the MIDI message format

To make it easier to understand, MIDI data is usually represented in either decimal (base 10) or

hexadecimal (base 16) numbers. On the Freaks, decimal is suffixed with [d]. Hex is suffixed with [h].

The MIDI standard uses 0-255 in the following way:

00 - 7F = 0-127 variable for data

Channel Commands Data 1 (0-127) Data 2 (0-127)

80 - 8F = Note-on (channels 1-16) Note number Velocity

90 - 9F = Note-off (channels 1-16) Note number Velocity

A0 - AF = Poly aftertouch (channels 1-16) Note number Aft. amount

B0 - BF = Controllers (channels 1-16) Controller number Controller value

C0 - CF = Programs (channels 1-16) Program number -

D0 - DF = Mono aftertouch (channels 1-16) Aftertouch amount -

E0 - EF = Pitchbend (channels 1-16) LSB MSB
