Instance Property


A key path generated by concatenating the identifiers of the parameter and its parents.


var keyPath: String { get }


When recording parameter values, hosts should bind to the parameter key path (unless an audio unit specifically documents that its parameter addresses are stable and persistent). The individual node identifiers in a key path are separated by periods (.). Passing a node’s key path to a parameter tree’s value(forKeyPath:) method returns the same node.

var identifier: String

A non-localized, permanent name for the parameter node.

var displayName: String

A localized display name for the parameter node.

func displayName(withLength: Int) -> String

Another version of the display name, possibly truncated to a desired length.
