Class MidiFileWriter


public abstract class MidiFileWriter
extends Object

MidiFileWriter provides MIDI file writing services. There are three types of Standard MIDI File (SMF) formats, represented by integers 0, 1, and 2. Type 0 files contain a single track and represents a single song performance. Type 1 may contain multiple tracks for a single song performance. Type 2 may contain multiple tracks, each representing a separate song performance. See http://en.wikipedia.org/wiki/MIDI#MIDI_file_formats for more information.
