get :: C parser => Int -> Int -> Fallible parser TSource

type ControllerValue = IntSource
type PitchBendRange = IntSource
type Pressure = IntSource
isNote :: T -> BoolSource
isNoteOn :: T -> BoolSource
NoteOn with zero velocity is considered NoteOff according to MIDI specification.
isNoteOff :: T -> BoolSource
NoteOn with zero velocity is considered NoteOff according to MIDI specification.
zeroKey :: PitchSource
A MIDI problem is that one cannot uniquely map a MIDI key to a frequency. The frequency depends on the instrument. I don't know if the deviations are defined for General MIDI. If this applies one could add transposition information to the use patch map. For now I have chosen a value that leads to the right frequency for some piano sound in my setup.
explicitNoteOff :: T -> TSource
Convert all NoteOn p 0 to NoteOff p 64. The latter one is easier to process.
implicitNoteOff :: T -> TSource
Convert all NoteOff p 64 to NoteOn p 0. The latter one can be encoded more efficiently using the running status.
toFloatController :: (Integral a, Fractional b) => a -> bSource
Map integral MIDI controller value to floating point value. Maximum integral MIDI controller value 127 is mapped to 1. Minimum integral MIDI controller value 0 is mapped to 0.

data Controller Source

We do not define Controller as enumeration with many constructors, because some controller have multiple names and some are undefined. It is also more efficient this way. Thus you cannot use case for processing controller types, but you can use Data.List.lookup instead. 

 maybe (putStrLn "unsupported controller") putStrLn $
 lookup ctrl $
    (portamento, "portamento") :
    (modulation, "modulation") :
    []

fromController :: Controller -> IntSource
toController :: Int -> ControllerSource
increasePitch :: Int -> Pitch -> PitchSource
subtractPitch :: Pitch -> Pitch -> IntSource
maximumVelocity :: Num quant => quantSource
The velocity of an ordinary key stroke and the maximum possible velocity.
normalVelocity :: Num quant => quantSource
toFloatVelocity :: (Integral a, Fractional b) => a -> bSource
64 is given as default value by the MIDI specification and thus we map it to 1. 0 is mapped to 0. All other values are interpolated linearly.
