ZMidi.Core.Canonical
Description
Convert a MidiFile into "canonical" form - i.e. expand any use of Running Status and translate Running Status high, NoteOn channel velocity 0 events to NoteOff events.
Documentation
canonical :: MidiFile -> MidiFile Source #
Convert an MidiFile into "canonical" form where any abbreviation introduced by Running Status is expanded.
Note - even with Running Status on the syntax tree is almost canonical (some expansion takes place in the Parser), so this translation is quite simplistic.
