I'm familiarizing myself with AKMusicTrack functions, specifically functions used to clear note data from a given sequence.
I can see that clearRange() will clear note data between a start and end range, and clearNote() will remove all events in the sequence of that note value.
Does anyone know of a function that will clear a single note? As in something like clearSingleNote(noteNumber MIDINoteNumber, position AKDuration, end AKDuration)?
You can use getMIDINoteData() to get an array of AKMIDINoteData, filter out the notes you don't want, then overwrite the music track using replaceMIDINoteData() with your filtered array:
// remove a C at timestamp 4.0
var trackData = myTrack.getMIDINoteData()
trackData = trackData.filter { $0.noteNumber =! 60 &&
$0.duration =! AKDuration(beats: 4.0) }
myTrack.replaceMIDINoteData(with: trackData)
There are more examples using getMIDINoteData() in the MIDIFileEditAndSync example project.
Right way:
trackData = trackData.filter {
!($0.noteNumber == 60 && $0.duration == AKDuration(beats: 4.0))
}
