Sound.MIDI.File.Event

MIDI messages in MIDI files. They are not a superset of the messages, that are used for real-time communication between MIDI devices. For these refer to Sound.MIDI.Message. Namely System Common and System Real Time messages are missing. If you need both real-time and file messages (say for ALSA sequencer), you need a custom datatype.

program :: T -> Maybe (Channel, Program)

anyController :: T -> Maybe (Channel, (Controller, Int))

get :: C parser => Fragile (T parser) T

put :: (Compression compress, C writer) => T -> T compress writer

The following functions encode various T elements into the raw data of a standard MIDI file.

type TrackEvent = (ElapsedTime, T)

getTrackEvent :: C parser => Fragile (T parser) TrackEvent

Each event is preceded by the delta time: the time in ticks between the last event and the current event. Parse a time and an event, ignoring System Exclusive messages.

type ElapsedTime = Integer

fromElapsedTime :: ElapsedTime -> Integer

toElapsedTime :: Integer -> ElapsedTime

mapBody :: (T -> T) -> TrackEvent -> TrackEvent

maybeMIDIEvent :: T -> Maybe T

maybeMetaEvent :: T -> Maybe T

maybeVoice :: T -> Maybe (Channel, T)

mapVoice :: (T -> T) -> T -> T
