An object that represents MIDI meta event messages.

## Declaration

```swift
class AVMIDIMetaEvent
```

## Overview

Overview You can’t modify the size and contents of this event once you create it. This doesn’t verify that the content matches the MIDI specification. You can only add AVMIDIMetaEvent.EventType.tempo, AVMIDIMetaEvent.EventType.smpteOffset, or AVMIDIMetaEvent.EventType.timeSignature to a sequence’s tempo track.
