Music Macro Language (MML) is a method of transcribing musical notation as sequence data, which then gets processed into binary performance data, akin to MIDI, for a computer to playback. Most popularly, this syntax can be used to create chiptune music.
Syntax
MML has many variations, but the majority of those languages share a similar syntax.
| Syntax | Description |
|---|---|
oX |
Set octave for the rest of notes before the next <, > and oX.For example, o6 will set the octave to 6.The range is depending on platform. |
c, d, e, f, g, a, b |
Play a note. Use + or - after the letter to specify a sharp or flat, respectively.A number should appear after the note; this number should denote the note's duration. 1 is a whole note, 2 is a half note, 4 a quarter note, 8 an eighth note, etc. If no duration is specified, then the duration will be the value specified by the l command.
|
r |
Play a rest. Similar to a normal note, the number after it defines its length. |
^ |
Play a tie (extending pervious note, rest or tie). Similar to a normal note, the number after it defines its length. |
<, > |
Decrease or increase octave by 1. The direction is depending on platform, but both of them should be opposite each other. |
lXX |
Defining the default length of a note when the length is not specified. For example, l4 will set the default length to a quarter note.
|
@ |
Set instrument. The range is depending on platform. |
v |
Set channel volume. The range is depending on platform. |
MML usage in SNES ROM hacking
There are a handful of tools known to incorporate MML syntax into editing the music for existing SNES games:
