SequencerA hardware or software device that plays back a MIDI
sequenceis known as a sequencer.

Class Summary Class Description InstrumentAn 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. MetaMessageA
MidiMessagethat is not meaningful to synthesizers, but that can be stored in a MIDI file and interpreted by a sequencer program.
MidiDevice.Infoobject contains assorted data about a
MidiDevice, including its name, the company who created it, and descriptive text.
MidiEventMIDI 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
MidiFileFormatobject encapsulates a MIDI file's type, as well as its length and timing information.
MidiMessageis the base class for MIDI messages.
MidiSystemclass provides access to the installed MIDI system resources, including devices such as synthesizers, sequencers, and MIDI input and output ports.
Patchobject represents a location, on a MIDI synthesizer, into which a single instrument is stored (loaded).
Sequenceis a data structure containing musical information (often an entire song or composition) that can be played back by a
SyncModeobject represents one of the ways in which a MIDI sequencer's notion of time can be synchronized with a master or slave device.

InvalidMidiDataExceptionindicates that inappropriate MIDI data was encountered.
MidiUnavailableExceptionis thrown when a requested MIDI component cannot be opened or created because it is unavailable.
