The MSC Concept
The MSC command structure and syntax is based on the general SysEx structure defined by MMA (MIDI Manufacturers
Association). It was released in 1991 as an extension to the general MIDI.
The raw MIDI information is written in hex octets (two hexadecimal numbers). Different software manufacturers might
present the MSC in an interpreted way and show the data in a more human readable form. This can of course be
nice, but since we cannot describe every way this can be presented, this manual is looking at the raw data.
The message format looks like this:
F0 7F
Device ID
02
Command Format
Command
Data
F7
F0 7F
is the header that identifies the message as "universal system exclusive" and a "real time" message.
Device ID
is the device or group number.
02
is a hex octet specifying that the message is MSC.
Command Format
is an octet that specifies the equipment type.
Command
is an octet that defines the command type
Data
is the actual data. This might change depending on the command type.
F7
is a closing octet finishing the message.
Device ID
The device ID is an octet actually divided into three different sections:
00 to 6F
:
This is the 112 different specific devices that can be identified.
