Struct PlaybackEvent 

pub struct PlaybackEvent {
    pub time_beats: f64,
    pub time_secs: f64,
    pub pitch_midi: u8,
    pub velocity: u8,
    pub duration_beats: f64,
    pub duration_secs: f64,
    pub pedal: bool,
    pub part_index: usize,
    pub channel: u8,
    pub is_metronome: bool,
}

A single sounding event suitable for audio playback engines (e.g. Web Audio, Tone.js).

Grace notes and rests are excluded. Chords are expanded to one event per pitch.

Fields

time_beats: f64

Absolute beat position from the start of the score.

time_secs: f64

Absolute time in seconds from the start of the score.

pitch_midi: u8

MIDI pitch number (0–127).

velocity: u8

MIDI velocity (1–127). Derived from Dynamic; defaults to 64. Boosted by +20 for Accent / Marcato articulations (clamped to 127).

duration_beats: f64

Sounding duration in beats. Halved for Staccato / Staccatissimo.

duration_secs: f64

Sounding duration in seconds.

pedal: bool

True when the note has pedal_start set (sustain pedal down).

part_index: usize

Index of the part this event originates from (useful for per-channel MIDI routing).

channel: u8

MIDI channel of the originating part (part.midi_channel). For Tone.js channel routing.

is_metronome: bool

true for metronome click events injected via MetronomeConfig.
