Sets a custom value for a custom parameter.

## Declaration

```swift
func setPathID(_ pathID: FxPathID, toParameter parameterID: UInt32, at time: CMTime) -> Bool
```

## Parameters

- `pathID`: Specified path ID for the parameter
- `parameterID`: Unique identifier for the parameter.
- `time`: Specified time to set the value.

## Return Value

Return Value Returns YES if the pathID is set successfully; NO otherwise.

## Discussion

Discussion Depending on the host application, the time value may be relative to the start of the timeline or to the start of the clip. See Understanding time in FxPlug.
