MidiSynth

Android MidiSynth Sample

Sample demonstrating how to use the MIDI API to receive and play MIDI messages coming from an attached input device (MIDI keyboard).

Introduction

The Android MIDI API (android.media.midi) allows developers to connect a MIDI device to an Android device and process MIDI messages coming from it.

This sample demonstrates some basic features of the MIDI API, such as:

  • Enumeration of currently available devices (including name, vendor, capabilities, etc)
  • Notification when MIDI devices are plugged in or unplugged
  • Receiving and processing MIDI messages

This sample contains a simple implementation of an oscillator and note playback.

Pre-requisites

  • Android SDK 28
  • Android Build Tools v28.0.3
  • Android Support Repository
