Struct Section 

pub struct Section {
    pub name: String,
    pub muted: bool,
    pub cycles: u32,
    pub bpm: u32,
    pub sig: (u8, u8),
    pub scale: Option<(PitchRoot, ScaleMode)>,
    pub patterns: Vec<PatternDef>,
    pub groups: Vec<GroupDef>,
}

One resolved section: its members and the state in force while it plays.

Everything a section sounds like lives here rather than on the Occurrence, because a section sounds the same wherever the arrangement puts it (§8.5). The only thing an occurrence adds is when.

Fields

name: String

muted: bool

A muted section still takes its time — it is a rest of its own length.

cycles: u32

How many cycles it lasts. Always >= 1.

bpm: u32

Tempo in force, after any bpm written inside the section (§8.5).

sig: (u8, u8)

Time signature in force.

scale: Option<(PitchRoot, ScaleMode)>

Default scale in force.

patterns: Vec<PatternDef>

Member pattern lines, in source order.

groups: Vec<GroupDef>

Groups declared inside the section, in source order.

Implementations

impl Section

pub fn cycle_seconds(&self) -> f64

How long one of this section’s cycles lasts, in seconds.

pub fn seconds(&self) -> f64

How long the whole section lasts, in seconds.

pub fn audible_on(&self, cycle: u32) -> impl Iterator<Item = &PatternDef>

The members audible on cycle (1-based, within this section), skipping the muted ones and those whose span (§8.3) excludes the cycle.
