# addRangeForInputValuesBelow(value:fullGainAtValue:fadeCurveType:subtree:)

Adds a child node that blends below a given value.

## Declaration

```swift
func addRangeForInputValuesBelow(value: Double, fullGainAtValue: Double, fadeCurveType: PHASECurveType, subtree: PHASESoundEventNodeDefinition)
```

## Parameters

- `value`: The value above which the child node blends.
- `fullGainAtValue`: A threshold such that the node applies a fade curve to the child node’s gain when the blend parameter is between value and this value.
- `fadeCurveType`: An option that determines a rate of change for the child node’s gain over the fade range.
- `subtree`: A child node to blend.
