Alignable class
Aligned values
Aligned places a vector-like object in space, by fixing a local duration interpolating
the vector to a specific point in time. The aligned value must be an instance of
HasDuration, with view duration
This is analogous to alignment in a graphical program. To align something at onset, midpoint or offset, use 0, 0.5 or 1 as the local duration value.

aligned :: Time -> Alignment -> v -> Aligned v Source
Align the given value so that its local duration occurs at the given time.
realign :: (HasDuration a, Transformable a) => Alignment -> Aligned a -> Aligned a Source
renderAligned :: (HasDuration a, Transformable a) => (Span -> a -> b) -> Aligned a -> b Source
Render an aligned value. The given span represents the actual span of the aligned value.
renderAlignedVoice :: Aligned (Voice a) -> Score a Source
Convert an aligned voice to a score.
renderAlignedNote :: Aligned (Note a) -> Event a Source
Convert an aligned note to an event.
renderAlignedDuration :: Aligned Duration -> Span Source
Convert an aligned duration to a span.
