A typical simple MIDI application might begin by invoking one or more <code>MidiSystem</code> methods to learn what devices are installed and to obtain the ones needed in that application. <p> The class also has methods for reading files, streams, and URLs that contain standard MIDI file data or soundbanks. You can query the <code>MidiSystem</code> for the format of a specified MIDI file. <p> You cannot instantiate a <code>MidiSystem</code>; all the methods are static.<P><HR><P><!-- ======== INNER CLASS
