nullreference 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.
NullPointerExceptionis an example of typical and acceptable run time exception for such cases.
ControllerEventListenerinterface should be implemented by classes whose instances need to be notified when a
Sequencerhas processed a requested type of MIDI control-change event.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.An
InvalidMidiDataExceptionindicates that inappropriate MIDI data was encountered.The
MetaEventListenerinterface should be implemented by classes whose instances need to be notified when a
Sequencerhas processed a
MidiMessagethat is not meaningful to synthesizers, but that can be stored in a MIDI file and interpreted by a sequencer program.A
MidiChannelobject represents a single MIDI channel.
MidiDeviceis the base interface for all MIDI devices.A
MidiDevice.Infoobject contains assorted data about a
MidiDevice, including its name, the company who created it, and descriptive text.
Receiverwhich represents a MIDI input connector of a
Transmitterwhich represents a MIDI input connector of a
MidiDevice.getTransmitter()).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
MidiFileFormatobject encapsulates a MIDI file's type, as well as its length and timing information.
MidiMessageis the base class for MIDI messages.The
MidiSystemclass provides access to the installed MIDI system resources, including devices such as synthesizers, sequencers, and MIDI input and output ports.A
MidiUnavailableExceptionis thrown when a requested MIDI component cannot be opened or created because it is unavailable.A
Patchobject represents a location, on a MIDI synthesizer, into which a single instrument is stored (loaded).A
MidiEventobjects and typically does something useful in response, such as interpreting them to generate sound or raw MIDI output.A
Sequenceis a data structure containing musical information (often an entire song or composition) that can be played back by a
Sequencerobject.A hardware or software device that plays back a MIDI
sequenceis known as a sequencer.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.A
ShortMessagecontains a MIDI message that has at most two data bytes following its status byte.A
Soundbankcontains a set of
Instrumentsthat can be loaded into a
SoundbankResourcerepresents any audio resource stored in a
SysexMessageobject represents a MIDI system exclusive message.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.A
VoiceStatusobject contains information about the current status of one of the voices produced by a
