chunkSizesFromLazyTime :: LazyTime -> T ChunkSize

piecewiseConstant :: Storable y => T StrictTime y -> T y

piecewiseConstantInit :: Storable y => y -> T StrictTime y -> T y

piecewiseConstantInitWith :: Storable c => (y -> c) -> c -> T StrictTime [y] -> T c

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

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

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

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

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

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

type Instrument y yv = Instrument y (T yv)

type Bank y yv = Bank y (T yv)

sequenceCore :: (Storable yv, C yv) => ChunkSize -> Channel -> Program -> Modulator Note (T yv) -> Filter (T yv)

sequence :: (Storable yv, C yv, C y) => ChunkSize -> Channel -> Instrument y yv -> Filter (T yv)

sequenceModulated :: (Storable c, Storable yv, C yv, C y) => ChunkSize -> T c -> Channel -> (T c -> Instrument y yv) -> Filter (T yv)

sequenceMultiModulated :: (Storable yv, C yv, C y) => ChunkSize -> Channel -> instrument -> Modulator (instrument, Note) (Instrument y yv, Note) -> Filter (T yv)

applyModulation :: Storable c => T c -> Modulator (T c -> instr, note) (instr, note)

advanceModulationLazy :: Storable a => LazyTime -> State (T a) LazyTime

advanceModulationStrict :: Storable a => LazyTime -> State (T a) LazyTime

advanceModulationChunky :: Storable a => LazyTime -> State (T a) LazyTime

sequenceMultiProgram :: (Storable yv, C yv, C y) => ChunkSize -> Channel -> Program -> [Instrument y yv] -> Filter (T yv)

renderInstrument :: C y => Bank y signal -> Note -> signal

Instrument parameters are: velocity from -1 to 1 (0 is the normal pressure, no pressure aka NoteOff is not supported), frequency is given in Hertz

renderInstrumentIgnoreProgram :: C y => Instrument y signal -> Note -> signal

evaluateVectorHead :: NormalForm signal => signal -> t -> t

We have to evaluate the head value at each drop in order to avoid growing thunks that lead to a space leak.
