This is the Mohawk MIDI format.

It resembles the [[Mohawk archive format]] and [[Mohawk Sounds]] format. This is a work in progress and not everything is known about it yet. It is in Big Endian order.

== The Header ==
{| class="structure"
|4 bytes||mhwk_magic
|-
|unsigned long||size
|-
|4 bytes||midi_magic
|}

*''mhwk_magic'' is the string 'MHWK'. It's equal to the [[Mohawk archive format#IFF header|Mohawk format signature]]!
*''size'' is the effective resource size, minus the ADPC chunk size, minus 2.
*''midi_magic'' is the string 'MIDI'.

After this header come the chunks. Until now, 3 chunk types have been identified: '[[#The MThd Chunk|MThd]]', '[[#The Prg.23 Chunk|Prg#]]' and '[[#The MTrk Chunk|MTrk]]'.

== The MThd Chunk ==
''(MIDI Header?)''

{| class="structure"
|unsigned long||chunk_size
|-
|unsigned long||u0
|-
|unsigned short||u1
|}

== The Prg# Chunk ==
''(MIDI Programs?)''

{| class="structure"
|unsigned long||chunk_size
|-
|unsigned short||u0
|-
|unsigned short||u1
|-
|unsigned short||u2
|}

== The MTrk Chunk ==
''(MIDI Track?)''

{| class="structure"
|unsigned long||chunk_size
|}

Following this, it's unknown. It looks like it two shorts followed by a byte (''string_length'') and then ''string_length'' + 1 bytes that form a string. Here are some string examples:

* "Loop start"
* "Setup end"
* "Loop end"
* "Glowing.eff"
** Looks like a filename, but the file doesn't exist!
* "Ac bass"
