Interface Summary
Interface	Description
ControllerEventListener	The `ControllerEventListener` interface should be implemented by classes whose instances need to be notified when a `Sequencer` has processed a requested type of MIDI control-change event.
MetaEventListener	The `MetaEventListener` interface should be implemented by classes whose instances need to be notified when a `Sequencer` has processed a `MetaMessage`.
MidiChannel	A `MidiChannel` object represents a single MIDI channel.
MidiDevice	`MidiDevice` is the base interface for all MIDI devices.
MidiDeviceReceiver	`MidiDeviceReceiver` is a `Receiver` which represents a MIDI input connector of a `MidiDevice` (see `MidiDevice.getReceiver()`).
MidiDeviceTransmitter	`MidiDeviceTransmitter` is a `Transmitter` which represents a MIDI input connector of a `MidiDevice` (see `MidiDevice.getTransmitter()`).
Receiver	A `Receiver` receives `MidiEvent` objects and typically does something useful in response, such as interpreting them to generate sound or raw MIDI output.
Sequencer	A hardware or software device that plays back a MIDI `sequence` is known as a sequencer.
Soundbank	A `Soundbank` contains a set of `Instruments` that can be loaded into a `Synthesizer`.
Synthesizer	A `Synthesizer` generates sound.
Transmitter	A `Transmitter` sends `MidiEvent` objects to one or more `Receivers`.

Class Summary
Class	Description
Instrument	An instrument is a sound-synthesis algorithm with certain parameter settings, usually designed to emulate a specific real-world musical instrument or to achieve a specific sort of sound effect.
MetaMessage	A `MetaMessage` is a `MidiMessage` that is not meaningful to synthesizers, but that can be stored in a MIDI file and interpreted by a sequencer program.
MidiDevice.Info	A `MidiDevice.Info` object contains assorted data about a `MidiDevice`, including its name, the company who created it, and descriptive text.
MidiEvent	MIDI events contain a MIDI message and a corresponding time-stamp expressed in ticks, and can represent the MIDI event information stored in a MIDI file or a `Sequence` object.
MidiFileFormat	A `MidiFileFormat` object encapsulates a MIDI file's type, as well as its length and timing information.
MidiMessage	`MidiMessage` is the base class for MIDI messages.
MidiSystem	The `MidiSystem` class provides access to the installed MIDI system resources, including devices such as synthesizers, sequencers, and MIDI input and output ports.
Patch	A `Patch` object represents a location, on a MIDI synthesizer, into which a single instrument is stored (loaded).
Sequence	A `Sequence` is a data structure containing musical information (often an entire song or composition) that can be played back by a `Sequencer` object.
Sequencer.SyncMode	A `SyncMode` object represents one of the ways in which a MIDI sequencer's notion of time can be synchronized with a master or slave device.
ShortMessage	A `ShortMessage` contains a MIDI message that has at most two data bytes following its status byte.
SoundbankResource	A `SoundbankResource` represents any audio resource stored in a `Soundbank`.
SysexMessage	A `SysexMessage` object represents a MIDI system exclusive message.
Track	A MIDI track is an independent stream of MIDI events (time-stamped MIDI data) that can be stored along with other tracks in a standard MIDI file.
VoiceStatus	A `VoiceStatus` object contains information about the current status of one of the voices produced by a `Synthesizer`.

Exception Summary
Exception	Description
InvalidMidiDataException	An `InvalidMidiDataException` indicates that inappropriate MIDI data was encountered.
MidiUnavailableException	A `MidiUnavailableException` is thrown when a requested MIDI component cannot be opened or created because it is unavailable.
