/**
* A {@code Sequence} is a data structure containing musical information (often
* an entire song or composition) that can be played back by a {@link Sequencer}
* object. Specifically, the {@code Sequence} contains timing information and
* one or more tracks. Each {@link Track track} consists of a series of MIDI
* events (such as note-ons, note-offs, program changes, and meta-events). The
* sequence's timing information specifies the type of unit that is used to
* time-stamp the events in the sequence.
* <p>
* A {@code Sequence} can be created from a MIDI file by reading the file into
* an input stream and invoking one of the {@code getSequence} methods of
* {@link MidiSystem}. A sequence can also be built from scratch by adding new
* {@code Tracks} to an empty {@code Sequence}, and adding {@link MidiEvent}
* objects to these {@code Tracks}.
