Struct SequenceStep 

pub struct SequenceStep {
    pub parameters: Vec<ParameterTarget>,
    pub duration_notes: f64,
}

A single step in a sequencer pattern.

Each step carries zero or more parameter locks (p-locks): specific parameter values that are sent when the step becomes active. Parameters not listed in parameters keep their current value — they are not reset or cleared.

Duration

duration_notes expresses the step length in quarter-note units at the current tempo:

duration_notes	Musical duration
4.0	whole note
2.0	half note
1.0	quarter note
0.5	eighth note
0.25	sixteenth note
1.5	dotted quarter
…	any value >= 0

Fields

parameters: Vec<ParameterTarget>

Parameter target locks for this step.

duration_notes: f64

Step duration in quarter-note units.

Implementations

impl SequenceStep

pub fn new(parameters: Vec<ParameterTarget>, duration_notes: f64) -> Self

Create a new step with the given p-locks and duration.

pub fn single( node_id: impl Into<NodeId>, param: impl Into<String>, value: f32, duration_notes: f64, ) -> Self

Create a single-parameter step (convenience constructor).

pub fn duration_samples(&self, tempo: f32, sample_rate: f32) -> u64

Return the step duration in audio samples for the given tempo and sample rate.

quarter_note_samples = (60.0 / tempo) * sample_rate
