Struct Loop 

pub struct Loop {
    pub start: usize,
    pub end: usize,
    pub crossfade: f64,
}

A sustain loop, in source frames.

The container stores a loop as two things and nothing else: the stroke stops at end, and the record the loop starts at carries the mark bit. Loop detune, loop decay, and whether the editor called this a short loop or a long one are not stored anywhere, so a caller that needs them cannot have them.

Fields

start: usize

First frame of the loop.

end: usize

One past its last frame. Audio after it is not encoded.

crossfade: f64

Frames of the loop’s tail that fade into the frames before start. The fade is applied to the samples here, because that is where the instrument reads it from. Fractional, because a project can state it as a percentage of the loop rather than a frame count, and dropping the fraction moves the fade a field. Inferred from specimens; not confirmed on hardware.

Implementations

impl Loop

pub fn new(start: usize, end: usize) -> Loop

A loop over start..end with no crossfade.
