Struct EnvelopeBlock

pub struct EnvelopeBlock<S>
where
    S: Sample,
{
    pub attack: Parameter<S>,
    pub decay: Parameter<S>,
    pub sustain: Parameter<S>,
    pub release: Parameter<S>,
    /* private fields */
}

ADSR envelope generator block for amplitude and parameter modulation.

Fields

attack: Parameter<S>

Attack time in seconds.

decay: Parameter<S>

Decay time in seconds.

sustain: Parameter<S>

Sustain level (0.0 - 1.0).

release: Parameter<S>

Release time in seconds.

Implementations

impl<S> EnvelopeBlock<S>

where S: Sample,

pub fn new( attack: f64, decay: f64, sustain: f64, release: f64, ) -> EnvelopeBlock<S>

Create an EnvelopeBlock with given ADSR parameters. Times are in seconds, sustain is a level from 0.0 to 1.0.

pub fn note_on(&mut self)

Trigger the envelope (note on).

pub fn note_off(&mut self)

Release the envelope (note off).

pub fn reset(&mut self)

Reset the envelope to idle state.
