Music Macro Language
Music Macro Language (MML) is a music description language used in sequencing music on computer and video game systems.
MML is sometimes known as Music Markup Language, by conflation with the XML musical notation markup language of that name. For instance, what the video game Mabinogi refers to as "Music Markup Language" is actually a typical implementation of Music Macro Language.
History
The history of MML is related to the history of computing hardware.
Background
Early automatic music generation functions were used in arcade games, which used many computer sounds. An example of an early popular Arcade game with music is The Circus from Exidy Corporation in 1977.
The boom in Japanese video games was heralded in 1978 by the appearance in Japanese game centers (Amusement arcades) of Space Invaders by TAITO Corpolation.[1] The Yellow Magic Orchestra used more sampling music motif in their games. Their sound has been reproduced on Moog synthesizers. Others were mostly played by acoustic instruments. The Circus and Space Invaders's music is both hard circuit music and sounds.
Many similar Space Invaders-style games were created. Melodic spinoffs are relevant to the development of MML, especially Melody part III, Space War PART III or the Music Invaders made by Sanritsu Electoric Corpolation in 1978.
The music was all proprietary (closed source). The 1978 release of the Programmable interval timer by Intel was significant. The Intel 8253 Mode 3 Square Wave generator was used for music, in the Kit computer MZ-40K(My computer Doctor (Maikon Hakase マイコン博士/まいこんはかせ)) by SHARP Corporation, made in Japan at May 1978. Another Micro computer BASIC MASTER MB-6880(ja)BASIC Master (BASIC Master ベーシックマスター) used a 5Bit D/A converter music automated reference signal. Also important was the development of a method to generate using BASIC software.[2] The machine was assembled by Hitachi, Ltd. and made in Japan in September 1978.
The MZ-40K featured an open architecture and program sources.[3]
Versions
Classical MML
The first commands for classical MML appeared in the internal architecture of the SP-1002 MONITOR IOCS[4] and SP-5001 BASIC Operating Systems on the MZ-80K 8-bit[5] computer. Made by SHARP Corporation at 1978 in Japan.[6] It incorporated Intel 8253 hardware and memory mapped I/O. The sound-related BASIC Statements were MUSIC, TEMPO, and BEEP. [7]
Syntax
Classical MML as used in BASIC is described here. "MML Commands" are supplied to the MUSIC statement. Notes are specified in a three-octave range. A song is a sequence of mono single tones.
"+" (or in some old code, "￣") indicates upper octave, "- " (or in some old code, "＿") indicates the lower octave. The characters "CDEFGAB" correspond to a scale ("Doremi Faso Lassi"). A semitone is indicated by following the note with a '#' character. The note names are followed by a tone length, indicated by a number from 0-9. Similarly, R indicates a rest, and is also followed by a number from 0-9 indicating length. Sound length Internal value × TEMPO values.Tone length Demisemiquaver is 0(SP-1002 Internal value is 1)- Whole note is 9(SP-1002 Internal value is 32). Music played on Call to $0030 SP-1002 IOCS program routine.[8]

Modern MML
Modern MML originally appeared in Microsoft BASIC and was common in the early 1970s and 1980s on 8-bit and 16-bit era Japanese personal computers. The NEC PC-6001 included Microsoft BASIC and the Programmable Sound Generator in 1981. The MML was especially popular on NEC's personal computers, such as the NEC PC-8801.[10] With the 2001 release of the mck (Music Creation Kit) software for compiling MML to play music on the Nintendo Entertainment System,[11] awareness and use of MML increased.[12] MML is presently popular among Japanese electronic musicians[10] and musicians who create chiptunes[13] as a way to write music for the Nintendo Entertainment System.
Syntax
Modern MML originated as a sub-language of BASIC, then generally included in ROM on micro-computers. A PLAY statement uses an argument to define a string of tones that the sound-chip played. MML code has a simple text format whereby letters and numbers are used to describe the musical notes to be played.[10] In addition, various implementations of MML add system extensions allowing parameters of audio synthesis to be altered with specialized commands or to simplify the entry of common musical figures such as arpeggios.
Though many platforms feature custom extensions and letter case requirements and other minor syntactical features vary slightly in some implementations, the fundamental syntax rules, commands and features that define MML and are present in whole or in part in all implementations are as follows:[10][14]
cdefgab— The lettersatogcorrespond to the musical pitches and cause the corresponding note to be played. Sharp notes are produced by appending a+or#, and flat notes by appending a-. The length of a note is specified by appending a number representing its length as a fraction of a whole note — for example,c8represents a C eighth note, andf+2an F♯ half note.r— A rest. The length of the rest is specified in the same manner as the length of a note — for example,r1produces a whole rest.o— Followed by a number,oselects the octave the instrument will play in.>,<— Used to step up or down one octave.l— Followed by a number, specifies the default length used by notes or rests which do not explicitly define one. For example,l8 g a b g l16 g a b gproduces a series of four eighth notes followed by a series of four sixteenth notes.v— Followed by a number, sets the volume of the instrument. The range of values allowed is dependent upon the specific sound hardware being used. Some implementations also allow an ADSR envelope to be applied to the amplitude of each note.t— Followed by a number, sets the tempo in beats per minute. On hardware with more than one sound channel, it is often possible to set each channel to a different tempo.
In addition to these, most implementations add their own keywords and symbols for system-specific enhancements or extensions.
Example
This example can be played using mml2mid, a Web-based MML to midi / MP3 conversion system.[15]

Standard Musical Expression (SMX)
SMX is similar to modern MML. In SMX, note length is specified via an L command (e.g. L4) rather than by writing a number after the note.[18] This code was used by QBasic's PLAY command.[19]
Languages, platforms and software
- Epic Games's ZZT and Super ZZT, as well as the open-source clone named MegaZeux, use a very compact variant of MML for the PLAY command, with only one channel for the PC Speaker
- Microsoft's QBASIC, BASICA, and GW-BASIC all feature a
PLAYstatement which takes a string argument in the SMX format.[20][21][22] The name "Music Macro Language" may originate with GW-BASIC, which provided a facility "to play music by embedding a music macro language into the string data type."[23] The SBasic compiler from the German magazine DOS Extra, produced by DMV Widuch, offers the same PLAY command, and a few-line BASIC programme could be compiled into a small (few KiB) tool to play any MML files (often called *.PLY) given on the command line. - The NEC PC-8801's BASIC dialect, N88-BASIC, used MML in its
PLAYstatement, as did several other implementations of BASIC produced or sold by NEC.[10][24]- Chiptune composer Yuzo Koshiro created a heavily modified version. According to Koshiro, it "was more a BASIC-style language at first, but I modified it to be something more like Assembly. I called it ‘Music Love'. I used it for all the Bare Knuckle Games."[25]
- The mck, pmck, and ppmck utilities for creating Nintendo Entertainment System music, and a number of other tools for creating music for other hardware, such as the Bandai WonderSwan, the TurboGrafx-16, and the Sega Genesis.[12]
- The xpmck utility for creating music for various systems, including the Sega Master System, Sega Game Gear, Sega Genesis, Nintendo Game Boy and Commodore 64.[26]
- Some cellular phones utilize MML as a ringtone format.[27] The RTTTL ringtone language exhibits many of the characteristics of MML.
- An escape sequence was defined to allow terminal programs play music encoded in MML. Because of this music in MML is sometimes called ANSI Music.[28]
- On MSX computer system built in MSX BASIC also uses MML with PLAY-command. Comma separated strings represent separate voice channels. Music hardware expansions such as MSX-Music, MSX-Audio and MSX-MIDI expand PLAY-command so that also FM-chips and external MIDI devices can be controlled through MML.
- OpenBSD and MirOS BSD offer /dev/speaker[29] in a GW-BASIC-compatible format
- Nexon's Mabinogi and XLGames's ArcheAge games use MML coding for their Music Composition skill.[30][31]
- NCSOFT's Aion uses MML syntax within its own scripting system to create custom melodies at players' houses.
