Sound.MIDI.File.Event

Description

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.

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

type TrackEvent = (ElapsedTime, T) Source #

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

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 Source #

fromElapsedTime :: ElapsedTime -> Integer Source #

toElapsedTime :: Integer -> ElapsedTime Source #

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

maybeMIDIEvent :: T -> Maybe T Source #

maybeMetaEvent :: T -> Maybe T Source #

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

mapVoice :: (T -> T) -> T -> T Source #
