class HasDuration s where

Methods

duration :: s a -> Duration s

Instances

HasDuration Voice

HasDuration Score

class HasOnset s where

Class of types with a position in time.

Onset and offset are logical start and stop time, i.e. the preferred beginning and end of the sound, not o the the time of the attack and damp actions on an instrument,

If a type has an instance for both HasOnset and HasDuration, the following laws should hold:

 duration a = offset a - onset a
 offset a >= onset a

implying

 duration a >= 0

Methods

onset :: s a -> Time s

  Get the onset of the given value.

Instances

HasOnset Track

HasOnset Score

(HasOnset a, ~ * t (Time a)) => HasOnset (AddOffset t a)

class HasOffset s where

Methods

offset :: s a -> Time s

  Get the offset of the given value.

Instances

HasOffset Score

HasOffset (AddOffset t s)

class HasPreOnset s where

Methods

preOnset :: s a -> Time s

class HasPostOnset s where

Methods

postOnset :: s a -> Time s

class HasPostOffset s where

Methods

postOffset :: s a -> Time s

Defaults

durationDefault :: (AffineSpace (Time s), HasOffset s, HasOnset s) => s a -> Duration s

Given HasOnset and HasOffset instances, this function implements duration.

onsetDefault :: (AffineSpace (Time s), HasOffset s, HasDuration s) => s a -> Time s

Given HasDuration and HasOffset instances, this function implements onset.

offsetDefault :: (AffineSpace (Time s), HasOnset s, HasDuration s) => s a -> Time s

Given HasOnset and HasOnset instances, this function implements offset.

Wrappers

newtype AddOffset t s a

(Stretchable a, ~ * t (Time a)) => Stretchable (AddOffset t a)

(HasOnset a, ~ * t (Time a)) => HasOnset (AddOffset t a)
