Description

Control curves which can be used as envelopes, for controlling filter parameters and so on.

Synopsis

constant :: (C y, C u) => T u y -> R s u y y constantVector :: T u y -> yv -> R s u y yv mapLinear :: (C w, C flat y, C y, C u) => y -> T u y -> w flat y -> w (S u y) y mapLinearDimension :: (C w, C y, C y, C u, C v) => T v y -> T (Mul v u) y -> w (S u y) y -> w (S (Mul v u) y) y mapExponential :: (C w, C flat y, C y, C u) => y -> T u q -> w flat y -> w (S u q) y

Primitives

constant Source

:: (C y, C u) => T u y value -> R s u y y

constantVector Source

:: => T u y amplitude -> yv value -> R s u y yv The amplitude must be positive! This is not checked.

Preparation

mapLinear :: (C w, C flat y, C y, C u) => y -> T u y -> w flat y -> w (S u y) y Source

mapLinearDimension Source

:: (C w, C y, C y, C u, C v) => T v y range: one is mapped to center + range * ampX -> T (Mul v u) y center: zero is mapped to center -> w (S u y) y -> w (S (Mul v u) y) y Map a control curve without amplitude unit by a linear (affine) function with a unit.

mapExponential :: (C w, C flat y, C y, C u) => y -> T u q -> w flat y -> w (S u q) y Source
