Wire
Inherits from: Instance → Object
Wire connects one or more Instances to form a processing graph of their streams. Each Wire connects a source and target instance, and a source and target "pin" within each of those instances. Pins are string identifiers that select which stream is to be carried by the wire.
At the moment, only audio streams are supported, but this may expand in the future.
The following instances may be connected by Wires:
