dart_midi Fork

A Dart package that provides a parser and writer implementation for MIDI data. This package is a fork of the original dart_midi library, created by Filip Grzywok, and has been expanded with new features, bug fixes, and performance improvements.

The byte decoding and writing code is originally based on the JavaScript library midi-file.

Example

import 'dart:io';
import 'package:dart_midi_pro/dart_midi_pro.dart';

// Open a file containing MIDI data
var file = File('sample_midi.mid');

// Construct a MIDI parser
var parser = MidiParser();

// Parse MIDI directly from file. You can also use parseMidiFromBuffer to directly parse List<int>
MidiFile parsedMidi = parser.parseMidiFromFile(file);

// You can now access your parsed [MidiFile]
print(parsedMidi.tracks.length.toString());

// Construct a MIDI writer
var writer = MidiWriter();

// Let's write and encode our MIDI data again
// You can also control `running` flag to compress file and  `useByte9ForNoteOff` to use 0x09 for noteOff when velocity is zero
writer.writeMidiToFile(parsedMidi, File('output.mid'));
