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

Adds a child node that blends below a given value.

```
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.
