Struct DrumKit 

pub struct DrumKit { /* private fields */ }

A playable drum kit: MIDI note → a pre-rendered one-shot.

Implementations

impl DrumKit

pub fn general_midi(sample_rate: u32) -> Self

The General MIDI drum map, synthesized once at sample_rate.

pub fn with_max_voices(self, max: usize) -> Self

Set the polyphony cap — the number of simultaneous hits before the oldest is stolen with a short fade (builder style; default 32, clamped to ≥ 1).

pub fn note_on(&mut self, note: Note, velocity: f32)

Strike the drum mapped to note (velocity scales its level). Notes with no mapped piece are ignored.

pub fn notes(&self) -> impl Iterator<Item = u8> + '_

The MIDI notes this kit responds to.

pub fn active_voices(&self) -> usize

Number of drums still ringing.

Trait Implementations

impl AudioSource for DrumKit

fn fill(&mut self, out: &mut [f32]) -> usize

Fill out with the next block of interleaved-stereo audio.

fn reset(&mut self)

Rewind the source to its start (playback position / phase to zero). Defaults to a no-op; a looping source overrides it so a transport can restart it from the top. AdaptiveMusic::reset calls this on each layer.
