Sound.MIDI.Event
Description
Datatype for MIDI events as they can be sent to a synthesizer. That is, no timing is handled here.
Taken from Haskore.

type ControllerValue = IntSource
type PitchBendRange = IntSource
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.
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.
toFloatController :: (Integral a, Fractional b) => a -> bSource
fromVelocity :: Velocity -> IntSource
toVelocity :: Int -> VelocitySource
fromProgram :: Program -> IntSource
fromChannel :: Channel -> IntSource
increasePitch :: Int -> Pitch -> PitchSource
subtractPitch :: Pitch -> Pitch -> IntSource
