Synthesizer.MIDI.PiecewiseConstant

Convert MIDI events of a MIDI controller to a control signal.

type T = T StrictTime

duration :: T y -> LazyTime

zipWith :: C time => (a -> b -> c) -> T time a -> T time b -> T time c

initWith :: (y -> c) -> c -> T StrictTime [y] -> T c

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

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

pitchBend :: (C event, C y) => Channel -> y -> y -> Filter event (T y)

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

channelPressure :: (C event, C y) => Channel -> y -> y -> Filter event (T y)

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

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

This one is certainly not as efficient as bendWheelPressure since it first slices the event list and then zips the slices together.
