Struct SamplerNode 

pub struct SamplerNode { /* private fields */ }

A polyphonic sampler node.

Implementations

impl SamplerNode

pub fn new(sample_rate: f32) -> Self

pub fn midi_queue(&self) -> Arc<Mutex<Vec<MidiEvent>>>

Get the MIDI queue for pushing events from the MIDI/control thread.

pub fn instrument_slot(&self) -> Arc<ArcSwap<Option<LoadedInstrument>>>

Get the instrument slot. Control thread: call .store(Arc::new(Some(loaded))) to swap in a new instrument. This is a single atomic store — the RT thread sees the new instrument on the next process() call without any locking.

pub fn instrument_slot_mutex(&self) -> Arc<Mutex<Option<LoadedInstrument>>>

Compatibility shim: returns an Arc<Mutex<Option>> wrapper so existing code in graph_manager that calls .lock().unwrap() = Some(loaded) still compiles. The write goes through a thin Mutex wrapper that immediately stores into the ArcSwap.

pub fn reset_round_robin(&mut self)

Trait Implementations

impl DspNode for SamplerNode

fn process( &mut self, _inputs: &[Option<&[f32; 64]>; 8], output: &mut [f32; 64], _params: &mut ParamBlock, _sample_rate: f32, )

Process one buffer of audio.

fn type_name(&self) -> &'static str

Human-readable node type name (for serialization/UI).

fn capture_state(&self) -> StateBlob

Capture internal state for continuity transfer.

fn restore_state(&mut self, _state: StateBlob)

Restore internal state after a graph mutation.
