Struct DynamicTimeline 

pub struct DynamicTimeline { /* private fields */ }

Dynamic levels of one staff along a played measure order, so a marking carries on until the next one as in engraved music: a level (p, f, …) holds, an accent (sf, sfz, fz, rfz, sffz) lifts only its own moment, and a compound (fp, sfp, pf, …) attacks at the first level and continues at the second. A hairpin ramps the level across its notes towards the marking that follows it (or two dynamic steps up or down when none follows at once) and leaves the level there. Before the first marking notes play at velocity 64.

Implementations

impl DynamicTimeline

pub const DEFAULT_VELOCITY: u8 = 64

Velocity of a note before any dynamic marking.

pub fn for_staff(staff: &Staff, order: &[usize]) -> Self

Collect the markings and hairpins of every voice of staff along order (measure indices as played, repeats expanded). Grace and cue notes take no time.

pub fn velocity(&self, position: usize, beats: f64, own: Option<Dynamic>) -> u8

Velocity of a note at beats into the measure at position of the order: its own marking’s attack, the attack of a marking at the same moment in another voice, the point a hairpin has reached, or the level in force.
