(Musical Instrument Digital Interface) data.

For more information on using Java Sound see: Please note: In thejavax.sound.midi APIs, a null reference
parameter to methods is incorrect unless explicitly documented on the method
as having a meaningful interpretation. Usage to the contrary is incorrect
coding and may result in a run time exception either immediately or at some
later time. NullPointerException is an example of typical and
acceptable run time exception for such cases.- Since:

Interface Summary Interface Description ControllerEventListener TheControllerEventListenerinterface should be implemented by classes whose instances need to be notified when aSequencerhas processed a requested type of MIDI control-change event.MetaEventListener TheMetaEventListenerinterface should be implemented by classes whose instances need to be notified when aSequencerhas processed aMetaMessage.MidiChannel AMidiChannelobject represents a single MIDI channel.MidiDevice MidiDeviceis the base interface for all MIDI devices.MidiDeviceReceiver MidiDeviceReceiveris aReceiverwhich represents a MIDI input connector of aMidiDevice(seeMidiDevice.getReceiver()).MidiDeviceTransmitter MidiDeviceTransmitteris aTransmitterwhich represents a MIDI input connector of aMidiDevice(seeMidiDevice.getTransmitter()).Receiver AReceiverreceivesMidiEventobjects 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 MIDIsequenceis known as a sequencer.Soundbank ASoundbankcontains a set ofInstrumentsthat can be loaded into aSynthesizer.Synthesizer ASynthesizergenerates sound.Transmitter -
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 AMetaMessageis aMidiMessagethat is not meaningful to synthesizers, but that can be stored in a MIDI file and interpreted by a sequencer program.MidiDevice.Info AMidiDevice.Infoobject contains assorted data about aMidiDevice, 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 aSequenceobject.MidiFileFormat AMidiFileFormatobject encapsulates a MIDI file's type, as well as its length and timing information.MidiMessage MidiMessageis the base class for MIDI messages.MidiSystem TheMidiSystemclass provides access to the installed MIDI system resources, including devices such as synthesizers, sequencers, and MIDI input and output ports.Patch APatchobject represents a location, on a MIDI synthesizer, into which a single instrument is stored (loaded).Sequence ASequenceis a data structure containing musical information (often an entire song or composition) that can be played back by aSequencerobject.Sequencer.SyncMode ASyncModeobject represents one of the ways in which a MIDI sequencer's notion of time can be synchronized with a master or slave device.ShortMessage AShortMessagecontains a MIDI message that has at most two data bytes following its status byte.SoundbankResource ASoundbankResourcerepresents any audio resource stored in aSoundbank.SysexMessage ASysexMessageobject 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 AVoiceStatusobject contains information about the current status of one of the voices produced by aSynthesizer. -
Exception Summary Exception Description InvalidMidiDataException AnInvalidMidiDataExceptionindicates that inappropriate MIDI data was encountered.MidiUnavailableException AMidiUnavailableExceptionis thrown when a requested MIDI component cannot be opened or created because it is unavailable.
