Detailed Description

Manages per-voice processing of audio signals within the Vital synthesizer.

The SynthVoiceHandler is responsible for coordinating the various signal sources (oscillators, sampler, LFOs, envelopes, random LFOs, and filters) at the voice level. It handles note on/off events, voice allocation, pitch and modulation routing, and provides readouts of modulation and status outputs for use in the synthesizer’s modulation system and UI feedback.

output_map & vital::SynthVoiceHandler::getPolyModulations ( )
overridevirtual

Retrieves a map of all polyphonic modulations.

Retrieves a map of polyphonic modulation outputs for external monitoring or further processing.

Returns
A reference to an output_map of polyphonic modulation outputs.

Reimplemented from vital::SynthModule.

◆ getSample()

Sample * vital::SynthVoiceHandler::getSample ( )
inline

Gets the current sample from the producers module's sampler.

Returns
A pointer to the current Sample in use.

◆ getWavetable()

Wavetable * vital::SynthVoiceHandler::getWavetable ( int index)
inline

Gets a wavetable from the producers module.

Parameters
indexThe oscillator index.
Returns
A pointer to the requested Wavetable.

◆ init()

void vital::SynthVoiceHandler::init ( )
overridevirtual

Initializes the voice handler, creating and configuring all internal modules.

Initializes all components of the SynthVoiceHandler.

Sets up note articulation, producers (oscillators, sampler), modulation sources (LFOs, envelopes, random LFOs), filters, voice outputs, and modulation connections. Establishes all modulation and status outputs for external use.

Reimplemented from vital::VoiceHandler.

◆ midi_offset_output()

Output * vital::SynthVoiceHandler::midi_offset_output ( )
inline

Retrieves the MIDI offset output.

Returns
A pointer to the Output representing the MIDI offset.

◆ note_retrigger()

Output * vital::SynthVoiceHandler::note_retrigger ( )
inline

Retrieves the output that triggers when a note is retriggered.

Returns
A pointer to the Output representing note retriggers.

◆ noteOff()

void vital::SynthVoiceHandler::noteOff ( int note,
mono_float lift,
int sample,
int channel )
overridevirtual

Handles a note-off event, releasing voices or retriggering them in legato contexts.

Responds to note-off events, releasing voices or retriggering them under certain conditions (e.g., legato).

Parameters
noteThe MIDI note number.
liftThe release velocity (lift) value.
sampleThe sample index at which the note-off occurs.
channelThe MIDI channel of the note event.

Reimplemented from vital::VoiceHandler.

◆ noteOn()

void vital::SynthVoiceHandler::noteOn ( int note,
mono_float velocity,
int sample,
int channel )
overridevirtual

Handles a note-on event, starting or retriggering voices as appropriate.

Responds to note-on events, triggering voices and potentially retriggering envelopes if needed.

Parameters
noteThe MIDI note number.
velocityThe note-on velocity.
sampleThe sample index at which the note-on occurs.
channelThe MIDI channel of the note event.

Reimplemented from vital::VoiceHandler.

◆ prepareDestroy()

void vital::SynthVoiceHandler::prepareDestroy ( )

Prepares the voice handler for destruction, removing processors as needed.

Prepares the handler for destruction by removing modulation processors.

◆ process()

void vital::SynthVoiceHandler::process ( int num_samples)
overridevirtual

Processes all active voices for a given number of samples.

Processes the audio for the specified number of samples across all active voices.

Parameters
num_samplesThe number of samples to process.

Handles resetting voices if needed, updates active voice count and triggers, and processes modulation. Accumulates the resulting audio into the configured outputs.

Reimplemented from vital::VoiceHandler.

◆ shouldAccumulate()

bool vital::SynthVoiceHandler::shouldAccumulate ( Output * output)
overridevirtual

Determines if the given output should be accumulated across voices.

Determines if a given output should be voice-accumulated or not, allowing certain modulation outputs to remain per-voice without summation.

Parameters
outputThe output to check.
Returns
True if it should be accumulated, false otherwise.

Reimplemented from vital::VoiceHandler.
