Struct AffinePitchMap 

pub struct AffinePitchMap {
    pub multiplier: u8,
    pub addend: u8,
}

An affine pitch-class map x -> ax + b mod 12.

Fields

multiplier: u8

Multiplicative factor a, reduced modulo twelve.

addend: u8

Additive factor b, reduced modulo twelve.

Implementations

impl AffinePitchMap

pub const fn new(multiplier: u8, addend: u8) -> Self

Constructs an affine pitch-class map with canonical modulo-twelve factors.

pub const fn is_bijective(self) -> bool

Returns true exactly when the map is bijective over pitch classes.

pub fn apply(self, row: &ToneRow) -> PitchTransformOutput

Applies the affine map to row, returning a strict row only for bijections.
