Changelog of MIDI

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

v2.7.0

  • New meta event type SequencerSpecificEvent.
  • Implement Base.empty!(::MIDITrack) and Base.isempty(t::MIDITrack).

v2.6.0

  • New functions metric_time.
  • New functions duration_metric_time.

v2.5.0

  • Implement Note(pitch_name::String; position = 0, velocity = 100, duration = 960, channel = 0)
  • Implement Notes(notes_string::String, tpq::Int = 960)

v2.4.0

  • Implement Base.empty!(::Notes) and Base.isempty(::Notes).

v2.3.0

  • New functions is_octave.
  • Implement Base.keys(::Notes) and Base.eachindex(::Notes).

v2.2.0

  • New functions pitch_to_hz and hz_to_pitch

v2.1.0

  • Default value of MIDIFile.format changed from 0 to 1
  • Warning introduced to fileio_save for format 0 files with multiple tracks

v2.0.0

Breaking

  • MIDIEvent and MetaEvent are abstract types and they cannot be used directly.

Additions

  • New event types for each midi and meta events.

  • The list of new meta event types:

    • SequenceNumberEvent
    • TextEvent
    • CopyrightNoticeEvent
    • TrackNameEvent
    • InstrumentNameEvent
    • LyricEvent
    • MarkerEvent
    • CuePointEvent
    • MIDIChannelPrefixEvent
    • EndOfTrackEvent
    • SetTempoEvent
    • TimeSignatureEvent
    • KeySignatureEvent

  • The list of new midi event types:

    • NoteOffEvent
    • NoteOnEvent
    • AftertouchEvent
    • ControlChangeEvent
    • ProgramChangeEvent
    • ChannelPressureEvent
    • PitchBendEvent

v1.12.0

  • New function tempochanges

v1.11.0

  • Added qpm that returns the quarter notes per minute tempo of a given MIDI
  • Added bpm that returns the beats per minute of a given MIDI
  • Deprecated BPM

v1.10.0

  • Added time_signature that returns the time signature of a given MIDI.

v1.9.0

  • name_to_pitch now accepts flat names and pitch_to_name accepts flat keyword argument.

v1.8.0

  • DrumNote shorthand constructor, keyword constructor for Note and added DRUMKEY dictionary in constants.jl (originally in MusicVisualizations).

v1.7.0

  • Notes constructor allows values of tpq greater than 960.

v1.6.0

  • New function testnotes() that returns a test set of human-played notes.

v1.5.2

  • Correctly implement Base.copy(::Notes) to copy every note, instead of copying the high-level vector (which lead to all internal notes being the same object as the non-copied version).

v1.5.0

  • show for midi now states the contained tracks

v1.4.0

  • Added convenience function tracknames(midi)

v1.3.0

Improved the printing of TrackEvents. They now state the amount of elements in them, as well as listing how many or of each type. E.g.:

julia> midi.tracks
5-element Array{MIDITrack,1}:
 3-event MIDITrack: 0 MIDI, 3 Meta, 0 Sysex
 5729-event MIDITrack: 5728 MIDI, 1 Meta, 0 Sysex
 8467-event MIDITrack: 8466 MIDI, 1 Meta, 0 Sysex
 21487-event MIDITrack: 21486 MIDI, 1 Meta, 0 Sysex
 9773-event MIDITrack: 9772 MIDI, 1 Meta, 0 Sysex

v1.2.0

Removed deprecations.

v1.1.0

See #112

We have changed name_to_pitch so that "C4" corresponds to midi pitch 60.

v1.0.0

No change, just stable release.

v0.8.0

  • Two new super-useful functions: name_to_pitch and pitch_to_name.
  • Function testmidi() that returns the path to doxy.mid.

v0.7.0

Breaking

  • BPM(midi) does not return the value rounded to an integer anymore. It returns the computed division instead.

  • ms_per_tick has now two methods: either one that accepts tpq, bpm or one that accepts a midi file.

Improvements

  • BPM is now faster as it iterates over events.
  • Pretty printing for MIDIFile.
  • Added functions textevent and findtextevents that create and find text related meta events (lyrics, text, markers).
  • Possible to write a midi file directly from notes.

v0.6.2

  • Minor documentation Improvements.
  • Improvement on show of Notes, especially the vectorized form.

v0.6.0

We now drop support for Julia 0.6 and only support ≥ 0.7.

New addevents! function

  • Now there is not only addevent! to add events to an existing track, but also addevents! which is significantly faster than calling addevent! many times, because it uses the new addevent_hint function to add the events. Use addevents! to add multiple events in one go.

  • This also made addnotes significantly faster.

  • Internally we implemented a new adding function addevent_hint! which is able to skip all TrackEvents that surely lay before the new event to add.
