# midiNote

The MIDI note number.

## Declaration

```swift
var midiNote: Float { get set }
```

## Discussion

Discussion If the instrument within the AVMusicTrack destination audio unit supports fractional values, you use this to generate arbitrary tunings. The valid range of values depends on the destination audio unit, and is usually between 0.0 and 127.0.
