Note type

data Note a

A Note is a value with an onset and and offset in time. It is an instance of Transformable.

You can use value to apply a function in the context of the transformation, i.e.

 over value (* line) (delay 2 $ return line)

 (view value) . transform s = transform s . (view value)

Construction

note :: Iso (Span, a) (Span, b) (Note a) (Note b)

View a note as a pair of the original value and the transformation (and vice versa).

event :: Iso (Note a) (Note b) (Time, Duration, a) (Time, Duration, b)

View a note as an events, i.e. a time-duration-value triplet.

noteValue :: (Transformable a, Transformable b) => Lens (Note a) (Note b) a b

View the value in the note.
