Detailed Description

Abstract base for a single MPE voice.

Subclasses render audio and respond to note lifecycle; expression smoothing is handled here.

Member Function Documentation

active()

bool pulp::midi::MpeSynthVoice::active ( ) const

inline

advance_smoothers()

void pulp::midi::MpeSynthVoice::advance_smoothers ( )

inline

Called once per sample before rendering. Advances smoothers.

channel()

uint8_t pulp::midi::MpeSynthVoice::channel ( ) const

inline

finish_release()

void pulp::midi::MpeSynthVoice::finish_release ( )

inlineprotected

note_id()

MpeNoteGeneration pulp::midi::MpeSynthVoice::note_id ( ) const

inline

note_number()

uint8_t pulp::midi::MpeSynthVoice::note_number ( ) const

inline

on_note_off()

virtual void pulp::midi::MpeSynthVoice::on_note_off ( )

inlinevirtual

Called by the allocator when this voice should release.

on_note_on()

virtual void pulp::midi::MpeSynthVoice::on_note_on ( const MpeNoteState & note )

inlinevirtual

Called by the allocator when this voice is activated.

pitch_bend()

float pulp::midi::MpeSynthVoice::pitch_bend ( ) const

inline

pressure()

float pulp::midi::MpeSynthVoice::pressure ( ) const

inline

releasing()

bool pulp::midi::MpeSynthVoice::releasing ( ) const

inline

render()

virtual void pulp::midi::MpeSynthVoice::render ( float * out, int num_samples )

pure virtual

Render num_samples of audio into out (additive or replacing — subclass decides).

The allocator calls this once per block per active voice; subclasses should call advance_smoothers() at the start of each sample or block as appropriate.

reset()

virtual void pulp::midi::MpeSynthVoice::reset ( )

inlinevirtual

Hard-reset the voice (e.g. on allocation steal).

set_pitch_bend()

void pulp::midi::MpeSynthVoice::set_pitch_bend ( float semitones )

inline

set_pressure()

void pulp::midi::MpeSynthVoice::set_pressure ( float p )

inline

set_smoothing()

void pulp::midi::MpeSynthVoice::set_smoothing ( float coeff )

inline

Smoothing coefficient in [0, 1). 0 = instant; 0.99 = ~100 sample TC.

set_timbre()

void pulp::midi::MpeSynthVoice::set_timbre ( float t )

inline

timbre()

float pulp::midi::MpeSynthVoice::timbre ( ) const

inline

velocity()

uint8_t pulp::midi::MpeSynthVoice::velocity ( ) const

inline
