mml2smf

MML to Standard MIDI File converter

This utility is created for in-development MIDI synthesizer synthesis.js, but it can be used for general use cases.

The features are very limited for now.

Usage

From command line

$ npm install -g mml2smf

$ mml2smf test.mml
$ mml2smf test.mml -o output.mid
$ mml2smf -m cdefg -o test.mid
$ mml2smf -m "t140 o5l8q7 ccggaag4 ffeeddc4; o4l8 cgegcgeg >b<gfg>b<gc4" -o test.mid

From JavaScript

var mml2smf = require("mml2smf");

var smf = mml2smf("cdefg"); // returns Uint8Array
