Struct Latch 

pub struct Latch {
    pub name: String,
    pub arm: Expr,
    pub fire: Expr,
    pub hold: f32,
}

One [latch] entry, compiled (ADR-0137): a gate armed on one condition and fired by the first rising edge of another inside the arming window.

Its slot is its position in Preset::latches, and that is the only place the mapping exists: the loader resolved the author’s name onto a reserved variable slot while compiling the bindings, so nothing per-frame looks a latch up by name. The same reasoning that keeps [smoothing] off Preset as a table — a fact about the preset, resolved once, and the preset does not change while it renders.

The two expressions are compiled without any latch name in scope, so a latch cannot read a latch. That is not a restriction waiting to be lifted: it is what makes “evaluate every latch, then the params that read them” a complete order rather than one with a dependency graph inside it.

Fields

name: String

The author’s name for it, which its bindings reference.

arm: Expr

While this holds (> 0.5), the latch is armed. Its fall re-arms.

fire: Expr

The rising edge that fires an armed latch.

hold: f32

How long the fired latch reads 1.0, in seconds. 0 is one frame.
