# MusicSequenceGetTempoTrack(_:_:)

Gets the tempo track for a music sequence.

## Declaration

```swift
func MusicSequenceGetTempoTrack(_ inSequence: MusicSequence, _ outTrack: UnsafeMutablePointer<MusicTrack?>) -> OSStatus
```

## Parameters

- `inSequence`: The music sequence whose tempo track you want to obtain.
- `outTrack`: On output, the tempo track.

## Return Value

Return Value A result code.

## Discussion

Discussion Each music sequence has a single tempo track. All tempo events are placed into this track, as well as some other events—such as the time signature from a MIDI file. The tempo track, once retrieved, can be edited and iterated over as can a music track. Most non-tempo events in a tempo track are ignored.
