Implementations

impl EngineHandle

pub fn rebuild_graph(&self)

Rebuild the master DSP graph from the current track list. Call this after mutating any track.kind. Cheap enough for live use — the audio callback sees the new graph on its next buffer.

NB: the old graph’s internal state (reverb tails, oscillator phases) is discarded. There’s a small audible discontinuity during preset swaps; acceptable given how rarely kind changes.
