Synthesizer.MIDI.PiecewiseConstant.ControllerSet

Treat a stream of MIDI events as parallel streams of MIDI controller events.

data T key a

Fields

initial :: Map key a

stream :: T StrictTime [(key, a)]

Instances

(Show key, Show a) => Show (T key a)

Monoid (T key y)

Ord key => Transform (T key y)

For reverse you must make sure, that all controller events have an corresponding initial value. Controllers that miss an initial value their last constant piece will be undefined.

Read (T key a)

(NFData key, NFData a) => NormalForm (T key a)

NFData Controller

fromChannel :: C event => Channel -> Filter event (T Controller Int)

maybeController :: C event => Channel -> event -> Maybe (Controller, Int)

controllerLinear :: C y => Controller -> (y, y) -> y -> Filter (T y)

controllerExponential :: C y => Controller -> (y, y) -> y -> Filter (T y)

pitchBend :: C y => y -> y -> Filter (T y)

pitchBend channel range center: emits frequencies on an exponential scale from center/range to center*range.

channelPressure :: C y => y -> y -> Filter (T y)

bendWheelPressure :: (C y, C y) => Int -> y -> y -> Filter (T (T y))

checkBendWheelPressure :: (Controller, Int) -> State T (Maybe T)

bendWheelPressureZip :: (C y, C y) => Int -> y -> y -> Filter (T (T y))
