data T key a

Instances

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

Monoid (T key y)

Read (T key a)

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

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.

fromChannel :: Channel -> Filter (T 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)

data BendModulation a

BendModulation a a

Instances

Eq a => Eq (BendModulation a)

Show a => Show (BendModulation a)

NFData a => NFData (BendModulation a)

shiftBendModulation :: C a => a -> BendModulation a -> BendModulation a

Multiply the pitch bend by a given factor. This way you can e.g. shift the pitch bend from around 1 to the actual frequency.

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