Audio features

Android Marshmallow 6.0 adds some enrichments to the audio features that we will cover in the upcoming sections.

Support for the MIDI protocol

The android.media.midi package was added in Android 6.0 (API 23).

With the new midi APIs, you can now send and receive MIDI (short for Musical Instrument Digital Interface) events in a much simpler way than earlier.

The package was built to provide us with capabilities to do the following:

• Connect and use a MIDI keyboard

• Connect to other MIDI controllers

• Use external MIDI synthesizers, external peripherals, lights, show control, and so on

• Allow dynamic music generation from games or music-creation apps

• Allow the creation and passing of MIDI messages between apps

• Allow Android devices to act as multi-touch controllers when connected to a laptop

<uses-feature android:name="android.software.midi" android:required="true"/>
