Public Member Functions
virtual	~NoteHandler ()
	Virtual destructor.
virtual void	allSoundsOff ()=0
	Immediately turns off all sounding notes and stops all sound production.
virtual void	allNotesOff (int sample)=0
	Turns off all currently active notes, optionally specifying a sample index for timing.
virtual void	allNotesOff (int sample, int channel)=0
	Turns off all currently active notes on a specific MIDI channel, optionally specifying a sample index.
virtual void	noteOn (int note, mono_float velocity, int sample, int channel)=0
	Handles a MIDI note-on event, starting a note with a specified velocity and timing.

	Handles a MIDI note-off event, releasing a currently active note.

Detailed Description

An interface for handling MIDI note events within a synthesizer or audio system.

The NoteHandler interface provides methods to respond to note-on and note-off events from MIDI, as well as commands to release all active notes and silence all sounds. Classes implementing this interface can manage voice allocation, envelope triggering, and other note-related behaviors in response to incoming MIDI data.

Constructor & Destructor Documentation

~NoteHandler()

virtual vital::NoteHandler::~NoteHandler ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

allNotesOff() [1/2]

virtual void vital::NoteHandler::allNotesOff ( int sample )

pure virtual

Turns off all currently active notes, optionally specifying a sample index for timing.

Parameters

sample

The sample index at which to turn off notes.

Implemented in vital::SoundEngine, vital::SoundEngine, and vital::VoiceHandler.

allNotesOff() [2/2]

virtual void vital::NoteHandler::allNotesOff ( int sample, int channel )

pure virtual

Turns off all currently active notes on a specific MIDI channel, optionally specifying a sample index.

Parameters

sample	The sample index at which to turn off notes.
channel	The MIDI channel for which to turn off notes.

Implemented in vital::SoundEngine, vital::SoundEngine, and vital::VoiceHandler.

allSoundsOff()

virtual void vital::NoteHandler::allSoundsOff ( )

pure virtual

Immediately turns off all sounding notes and stops all sound production.

Implemented in vital::SoundEngine, vital::SoundEngine, and vital::VoiceHandler.

noteOff()

virtual void vital::NoteHandler::noteOff ( int note, mono_float lift, int sample, int channel )

pure virtual

Handles a MIDI note-off event, releasing a currently active note.

Parameters

note	The MIDI note number (0-127).
lift	The release velocity (0.0 to 1.0).
sample	The sample index at which the note-off occurs.
channel	The MIDI channel on which the note-off occurred.

Implemented in vital::EffectsModulationHandler, vital::SoundEngine, vital::SoundEngine, vital::SynthVoiceHandler, and vital::VoiceHandler.

noteOn()

virtual void vital::NoteHandler::noteOn ( int note, mono_float velocity, int sample, int channel )

pure virtual

Handles a MIDI note-on event, starting a note with a specified velocity and timing.

Parameters

note	The MIDI note number (0-127).
velocity	The velocity of the note-on event (0.0 to 1.0).
sample	The sample index at which the note-on occurs.
channel	The MIDI channel on which the note-on occurred.

Implemented in vital::EffectsModulationHandler, vital::SoundEngine, vital::SoundEngine, vital::SynthVoiceHandler, and vital::VoiceHandler.
