dart_midi

A dart package that provides a parser and writer implementation for midi data.

The byte decoding and writing code is based on javascript library midi-file

Example

// 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'));
