DryWetMIDI 7.1.0

Rests redesigned

Now you can get rests between different types of objects and by any logic you will describe. Please read updated Rests section of the docs. This entails a breaking change – there is no ObjectType.Rest option anymore. So to get, for example, notes and rests between them you need to write following code:

var notesAndRests = midiFile
    .GetNotes()
    .WithRests(RestDetectionSettings.NoNotesByChannel);

To feel the power of the new approach, just take a look to the snippet:

var notesAndChordsAndRests = midiFile
    .GetObjects(ObjectType.Note | ObjectType.Chord)
    .WithRests(new RestDetectionSettings
    {
        KeySelector = obj => obj is Note note && note.NoteNumber > 100
            ? (object)note.NoteNumber
            : null
    });

Here we get notes, chords and rests between notes with note number > 100 separately for each note number. Rests won't be built for chords and notes with note number <= 100.

DryWetMIDI 6.1.0

This release focuses on unifying API to work with different MIDI objects.

Tools

First of all, new tool added – Repeater. It allows repeat MIDI data specified number of times with different options applied.

Also, some old tools were unified into single ones:

• TimedEventsQuantizer, NotesQuantizer and ChordsQuantizer have been replaced by new Quantizer tool which can quantize objects of different types simultaneously. More than that, it can now quantize start and end times at the same time, applying randomization if specified (and thus Randomizer tool is now obsolete). More info in the Quantizer article.
• NotesSplitter and ChordsSplitter have been replaced by new Splitter tool which can split objects of different types simultaneously. Also all methods from MidiFileSplitter class have been moved to the Splitter one. More info in the Splitter articles.

Objects managers

Also the work has been done on unifying separate manager classes for each object type. So now TimedEventsManager, NotesManager and ChordsManager classes are now obsolete. You should use TimedObjectsManager class now which can manage objects of different types simultaneously. More info in the Objects managers article.

New features and improvements

• Clone method has been moved from separate classes (like Note or TimedEvent) to ITimedObject interface.
• Split method has been moved from separate classes (like Note or Chord) to ILengthedObject.
• Added SetTime method to TimedObjectUtilities (SetTime within TimedEventsManagingUtilities is obsolete now).
• Added SetLength method to LengthedObjectUtilities (SetTimeAndLength methods within NotesManagingUtilities and ChordsManagingUtilities are obsolete now).
• Added MoveToStart method to PatternBuilder class.
• Added parameter of RepeatSettings type to PatternBuilder's Repeat methods.
• Added Note methods by a note string to PatternBuilder.
• Added Chord methods by a chord string to PatternBuilder.
• Changed default value of the Playback.InterruptNotesOnStop property to true.
• Parsing of MusicTheory.Note ignores case now.
• Parsing of Chord.GetNames method supports 7b9, add11, 7#11, 7+11, 7(#11) and 7aug11 chords now (see complete list of supported chords here).
• Added TimeType property to the PlaybackCurrentTimeWatcher.
• Constructor of the PlaybackCurrentTimeWatcher is now public so you can create different watchers.
• Added WatchOnlyRunningPlaybacks property to the PlaybackCurrentTimeWatcherSettings.
• Added SetPlaybackTimeType method to the PlaybackCurrentTimeWatcher.
• Added Note's constructor by pair of timed events.
• Added parameter of the TimedEventDetectionSettings type to timed events managing methods.
• Added Constructor and TimedEventDetectionSettings properties to NoteDetectionSettings.
• Added Constructor property to ChordDetectionSettings.

Small changes and bug fixes

• Added new total properties for MetricTimeSpan (#144).
• Handled big internal values within time spans conversions.
• Fixed: NotEnoughBytesPolicy is ignored on reading some events.
• Fixed: [TrackChunk](https://melanchall.github.io/drywetmidi/a...

DryWetMIDI 6.0.1
