# playbackCapacity

The maximum number of created effects that can be simultaneously played via calls to FFEffectStart. This number will always be equal to or less than the storageCapacity. A device driver may allow more effects to be created than the physical device can actually handle. Therefore, this number is an important parameter for FF designers.

## Declaration

```swift
var playbackCapacity: UInt32
```
