Expand description

One active voice in the sampler.

Fields§

§note: u8

MIDI note number.

§channel: u8

MIDI channel.

§velocity: f32

Velocity (0.0–1.0).

§position: f64

Current playback position in frames (sub-sample precision).

§pitch_ratio: f64

Playback speed ratio (accounts for pitch shifting).

§volume: f32

Volume multiplier from zone + velocity.

§phase: VoicePhase

Current lifecycle phase.

§envelope: EnvelopeState

ADSR envelope.

§zone_id: String

Zone id this voice is playing.

§articulation: ArticulationType

Articulation type (cached from zone).

§loop_start: usize

Loop start frame (if sustain loop).

§loop_end: usize

Loop end frame (if sustain loop).

§key_held: bool

Whether the key is still held.

Implementations§

Source §

impl SamplerVoice

Source

pub fn new( note: u8, channel: u8, velocity: f32, pitch_ratio: f64, volume: f32, zone: &SampleZone, ) -> Self

Source

pub fn release(&mut self)

Signal key release.

Source

pub fn is_done(&self) -> bool

Is this voice finished?

Source

pub fn advance(&mut self, buffer_frames: usize) -> f64

Advance position by one sample, handling loop points. Returns the current frame position for sample lookup.
