## Mixer

Object Hierarchy | Related C++ Class: Mixer

### Inheritance

SIObject

ProjectItem

Clip

ClipContainer

Mixer

### Introduced

v4.0

### Description

This object represents the Animation Mixer, which is nested directly under the Model. The Mixer object is a ClipContainer and so provides access to the standard elements of a mixer: its Tracks, Transitions, Clips, and ClipRelations.
You can check if an object has a mixer by calling the Model.HasMixer method. If it doesn't, you can create one with the Model.AddMixer method.
The Mixer stores all of the Model's high-level animation and audio clips, so when you call its base property ClipContainer.Clips, you get a collection of clips only on the current model (there is no recursion). If any of these are compound clips, none of its contents are returned, just the top level.
