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][1]) 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.
