Struct Ducker 

pub struct Ducker { /* private fields */ }

Ducker (Q148)

A dedicated sidechain ducking processor: a key (sidechain) input drives gain reduction on the main signal. When the key envelope is at or above the threshold, the main signal is attenuated by up to amount; the reduction tracks the key level with independent attack/release ballistics and recovers when the key falls silent.

Parameter reads via ModulatedParam (Q147)

amount and threshold are read through ModulatedParam: the panel knob is the base, and the corresponding bipolar CV input is summed in through the attenuverter on the ModulatedParam ±5 V scale. This makes ModulatedParam a live knob+CV read path rather than an unused export.

Implementations

impl Ducker

pub fn new(sample_rate: f64) -> Self

pub fn set_amount(&mut self, amount: f64)

Set the duck-depth knob (0..1), the base of the amount ModulatedParam.

pub fn amount(&self) -> f64

Current duck-depth knob (0..1).

pub fn set_threshold(&mut self, threshold: f64)

Set the threshold knob (0..1), the base of the threshold ModulatedParam (mapped to a 0..5 V key level).

pub fn threshold(&self) -> f64

Current threshold knob (0..1).
