ADSR (Attack / Decay / Sustain / Release) envelope.

val exponential : ?init:float -> unit -> float -> float t

Exponential decay with given parameter.

val exponential_hl : ?init:float -> unit -> float -> float t

Same as above but taking half-life as parameter.

val ramp : 
  ?kind:[< `Exponential | `Linear Linear ] ->
  unit ->
  ?from:float ->
  ?target:float ->
  float ->
  float t

Affine from a value to a value in a given time.
