+ <![CDATA[
+The Android MIDI API ([android.media.midi][1]) allows developers to connect a MIDI device to Android
+and process MIDI signals coming from it. This sample demonstrates some basic features of the MIDI
+API, such as enumeration of currently available devices (Information includes name, vendor,
+capabilities, etc), notification when MIDI devices are plugged in or unplugged, and receiving MIDI
+signals. This sample contains a simple implementation of oscillator and play sound for incoming MIDI
+signals.
