A Flutter plugin for sending and receiving MIDI messages between Flutter and physical and virtual MIDI devices.

Wraps CoreMIDI and android.media.midi in a thin dart/flutter layer. Works with USB and BLE MIDI connections on Android, and USB, network(session) and BLE MIDI connections on iOS.

Getting Started

This plugin is build using Swift and Kotlin on the native side, so make sure your project supports this.

Import flutter_midi_command

import 'package:flutter_midi_command/flutter_midi_command.dart';

  • Get a list of available MIDI devices by calling MidiCommand().devices which returns a list of MidiDevice
  • Start scanning for BLE MIDI devices by calling MidiCommand().startScanningForBluetoothDevices()
  • Connect to a specific MidiDevice by calling MidiCommand.connectToDevice(selectedDevice)
  • Stop scanning for BLE MIDI devices by calling MidiCommand().stopScanningForBluetoothDevices()
  • Disconnect from the current device by calling MidiCommand.disconnectDevice()
  • Listen for updates in the MIDI setup by subscribing to MidiCommand().onMidiSetupChanged
  • Listen for incoming MIDI messages on from the current device by subscribing to MidiCommand().onMidiDataReceived, after which the listener will recieve inbound MIDI messages as an UInt8List of variable length.
  • Send a MIDI message by calling MidiCommand.sendData(data), where data is an UInt8List of bytes following the MIDI spec.
  • Or use the various MidiCommand subtypes to send PC, CC, NoteOn and NoteOff messsages.
