Struct MelodyGenerator 

pub struct MelodyGenerator {
    pub scale: Scale,
    pub octave: i32,
    pub step_bias: f32,
    pub rest_prob: f32,
    pub chord_weight: f32,
    /* private fields */
}

Generates melodic lines that follow a scale and chord progression.

Fields

scale: Scale

octave: i32

step_bias: f32

Probability of stepwise motion vs leap.

rest_prob: f32

Probability of resting (silence) per note.

chord_weight: f32

How much to lean toward chord tones.

Implementations

impl MelodyGenerator

pub fn new(scale: Scale, octave: i32) -> Self

pub fn next_note(&mut self, chord: &Chord) -> Option<f32>

Generate the next note. Returns None for a rest, Some(freq) for a note.

pub fn phrase( &mut self, n: usize, chord: &Chord, beat_dur: f32, ) -> Vec<(Option<f32>, f32)>

Generate a phrase of n notes, returning (frequency, duration) pairs.
