Type 0 Files Type 0 Files Type 0 Files
Type 0 files hold a single track of sequence data
[header chunk] [trk 1]
Type 1 Files Type 1 Files Type 1 Files
Type 1 files hold chunks of data representing parallel track
information.
[header chunk] [trk 1]
[trk 2]
[trk 3]
Type 2 Files Type 2 Files Type 2 Files
Type 2 files handle sets of independant sequences by treating
each track chunk as a separate sequence.
[header chunk] [seq 1] [seq 2] [seq 3]
Format of chunks
chunk identifier | chunk size | actual chunk data |
4 bytes | 4 bytes | chunk size bytes |
Only 2 types of chunk are currently defined: Header chunks and
track chunks.
Header chunks
Current format of Header chunk is:
chunk identifier | chunk size | actual chunk data |
"MThd" | 00 00 00 06 |
word0: file format 0,1 or 2
word1: number of track chunks in file
word2: timing division information
Track chunks Track chunks Track chunks
Current format of Track chunk is:
chunk identifier | chunk size | actual chunk data |
"MTrk" | 1 or more 'events' |
Format of events
Time field: time before the specified event occurs.
Intergral part of the 'gramatical description'
sintax of a midi file event, called 'delta times'
variable length format containing 7 real bits per byte.
The most significant bit (bit 7) is used to indicate either the continuation
or the end of the possibly multi-byte number
3 types of event:
1) a MIDI event
2) a SySex event.
3) a Mita event.
Midi events
Only channel messages, ie,
channel voice
or channel mode messages.
not system common messages
SysEx events
Normal Sysex messages use a modified form which includes an
additional length, ie bytecount field (stored as a variable
length number).
Sysex Event 1
F0 hex | length | data bytes |
variable len |
Sysex Event 2
F7 hex | length | data bytes |
? midi terminator | variable len |
If the Sysex message is sent as a single packet then the last data byte should
be the EOX (F7 hex) SysEx terminator. This may apper to be unnecessary since
a SysEx message length field is also included. Large Sysex can be broken up
unto time-stamped packets.
If a program wants to split a SysEx message into time stamped packets it does
it by using the F0 form for the first data packet, and F7 forms for any subsequen
packets. The last data byte of the last packet of information
containg a 'real' F7 hex data byte.
Meta Events
FF hex | meta | length | data bytes |
event | variable len | ||
type |
type(hex) | length | details | |
sequence no | 00 | 2 | 16-bit number representing a sequence number |
text event | 01 | variable | text describing anything at all |
sequence or track name | 03 | variable | another ascii text event |
instrument name | 04 | variable | an indication of the intrumentation to be used for a track |
end of track | 2F | 0 | This event must be used so that an exact ending point can be specified for a trk |
set tempo | 51 | 3 | a 24-bit number which represents microseconds per quarter note |
time signature | 58 | 4 | the time signature |
sequencer | 7F | variabl | this event allows |
specific | sequences to include their own sequencer specific info |
