data Boundary key value

Constructors

Boundary key value Bool

Instances

(Eq key, Eq value) => Eq (Boundary key value)

(Show key, Show value) => Show (Boundary key value)

data BoundaryExt key value

Constructors

BoundaryExt (Boundary key value)

AllOff (key -> Bool)

The predicate shall return True, if a certain key shall be released by the AllOff statement. E.g. the predicate might check for the appropriate channel.

make :: C msg => x -> Velocity -> Bool -> msg

Instances

Make Pitch

Make PitchChannel

fromBnd :: (Make key, VelocityField value, C msg) => Boundary key value -> msg

bundle :: C msg => T m Relative Ticks -> T m Relative Ticks -> (PitchChannel, Velocity) -> Bundle m msg

lift :: (C msg, C msg) => (Boundary PitchChannel Velocity -> Boundary PitchChannel Velocity) -> msg -> Maybe msg

liftMaybe :: (C msg, C msg) => (Boundary PitchChannel Velocity -> Maybe (Boundary PitchChannel Velocity)) -> msg -> Maybe msg

transpose :: Int -> Boundary PitchChannel v -> Maybe (Boundary PitchChannel v)

Pitch.C a note event by the given number of semitones. Non-note events are returned without modification. If by transposition a note leaves the range of representable MIDI notes, then we return Nothing.

reverse :: Boundary PitchChannel v -> Maybe (Boundary PitchChannel v)

Swap order of keys. Non-note events are returned without modification. If by reversing a note leaves the range of representable MIDI notes, then we return Nothing.
