Fields

layer_type: LayerType

volume: f32

target_volume: f32

crossfade_rate: f32

active: bool

base_freq: f32

Base frequency for drone layers.

pattern: Vec<i32>

Pattern data — indices into a scale for melody/percussion.

pattern_cursor: usize

Current step in the pattern.

beat_accumulator: f32

Beats elapsed since last pattern step.

step_beats: f32

Beats per pattern step (reciprocal of note density).

Implementations

impl MusicLayer

pub fn new(layer_type: LayerType) -> Self

pub fn update(&mut self, dt: f32)

Drive the volume toward target_volume at crossfade_rate per second.

pub fn fade_in(&mut self, secs: f32)

Fade this layer in over secs seconds.

pub fn fade_out(&mut self, secs: f32)

Fade this layer out over secs seconds.

pub fn tick_pattern(&mut self, beat_delta: f32, scale: &Scale) -> Vec<NoteEvent>

Advance pattern playback by beat_delta beats. Returns note events.
