# MusicSequenceGetAUGraph(_:_:)

Gets the audio processing graph associated with a music sequence.

## Declaration

```swift
func MusicSequenceGetAUGraph(_ inSequence: MusicSequence, _ outGraph: UnsafeMutablePointer<AUGraph?>) -> OSStatus
```

## Parameters

- `inSequence`: The music sequence whose associated audio processing graph you want to get.
- `outGraph`: On output, the audio processing graph associated with the music sequence.

## Return Value

Return Value A result code.

## Discussion

Discussion If no audio processing graph is already associated with the music sequence, this function creates a default graph. The default graph contains an Instrument unit (of type DLSMusicDevice) and a dynamic compressor unit (of type DynamicCompressor). In this case, all music tracks in the music sequence have their outputs directed to the Instrument unit.
