  • The underlying meter.

    Declaration

    Swift

    public var meter: TimeSignature? = TimeSignature(4, 4)

  • A computed property that reflects the meter property, provided for convenience.

    Declaration

    Swift

    public var timeSignature: TimeSignature?

  • The underlying tempo.

    Declaration

    Swift

    public var tempo = Tempo(120)
  • BPM

    A computed property that reflects the tempo’s beats-per-minute value, provided for convenience.

    Declaration

    Swift

    public var BPM: Double

  • A NoteValue instance to easily change duration to another regular metric subdivision.

    Declaration

    Swift

    public var noteValue: NoteValue = .n_4

  • Initialize with a tempo, a meter, and a beat value.

    Declaration

    Swift

    public init(initialTempo: Tempo, initialMeter: TimeSignature, initialValue: NoteValue)
