sakuramml-rust

"sakruamml" is a MML/ABC to MIDI compier.

This compiler that converts the text of "cde" into MIDI files. It is a tool that allows you to easily create music. It is made with Rust and works on multiple platforms (macOS/Windows/Linux/WebAssembly).

Repository

Web Version (WASM)

Install

Binary - command line

Compile

Please install Rust compier.

$ git clone https://github.com/kujirahand/sakuramml-rust.git
$ cd sakuramml-rust
$ cargo build --release

target/release/sakuramml is compiler.

Sakura MML

Please make text file "test.mml". 　Execute the following command to generate a MIDI file.

$ sakuramml test.mml

Basic

o4 cdefgab>c<bagfedc

TR=1 CH=1 l1 ceg^

Harmony

l4 `ceg` `dfa`8 `egb`8 `ceg`

Set TIME Pointer

// top
TIME(1:1:0) cdef
TIME(1:1:0) efga

// 2mes
TIME(2:1:0) cdef

SUB{...} command let time pointer back.

SUB{ cdef  c }
SUB{ efga  e }
     rrrr  g

Rhythm macro

In the rhythm macro, one character is treated as one instruction regardless of uppercase or lowercase letters. Rhythm macro definitions are described as "$(char){definition}".

// define macro
$b{n36,}
$h{n42,}
$o{n46,}
// new macro
$S{n37,}
CH(10)
// sample
Rhythm{
　[4　l8
　　　brSr bbsr r-1
　　　hoho hoho
　]
}

How to specify tuplets

The tuplets are written as "DIV{...}", but "DIV" can be omitted and written as "{ceg}".

l4 DIV{cde} f DIV{gab} >c<
l4 {cde} f {gab} >c<

l4 {cde}c {gfe}d {c^d} e {d^e} f

The tuplets can nest.

l1 { c d {efe} d } c

Velocity

"(" decreases the velocity by 8, and ")" increases the velocity by 8.

v127 c ( c ( c (( c )) c ) c ) c

Harmony

`ceg` `dfa` `egb` `ceg`

Reservation notation

  • v.onTime(low, high, len, ...)　/ 省略形 v.T(low,high,len,...)
    • The value that should be specified for len is the tick. When specifying the note length, it should be written as !4, for example.
  • v.onNote(v1, v2, v3, ...)　/ abbreviation: v.N(v1,v2,v3,...)
  • t.onNote(v1, v2, v3, ...)　/ abbreviation: t.N(v1,v2,v3,...)
  • (ControllChange or PB or p).onTime(low, high, len, ...)
v.onTime(0,127,!1) l8cccccccc
BR(2) PB.onTime(-8192,0,!4) l4c PB(0) efg^

Macro

It can define Macro.

// define Macro
STR P1 = {cdefg}
#P1 = {cdefg}
// expand Macro
P1
#P1

The macro can replace with arguments. It replaces #?1 #?2 #?3 ...

// define macro
#Unison = { Key=#?2 Sub{ #?1 } Key=0 #?1 }
// expand macro with arguments 
#Unison{cde},7

Script

It can use IF/FOR/WHILE/FUNCTION script.

// IF 
INT A = 3
INT B = 5
IF (A == B) { PRINT({A == B}) } ELSE { PRINT({A != B}) }

// FOR
FOR (INT N=1; N < 5; N++) {
  PRINT(N)
}

Variables

It can define variables of INT, STR, and ARRAY types.

// define variables
INT I1=30
STR S1={abcd}
ARRAY A1=(1,2,3)

// use variables
PRINT(I1) // 30
PRINT(S1) // abcd
PRINT(A1) // (1,2,3)
PRINT(A1(2)) // 3
