new EnvelopeNode()
The EnvelopeNode class makes small draggable nodes or circles in a rectangular space that we refer to as an Envelope. Lines are drawn from one instance of EnvelopeNode to the next, and so can be used to determine or shape the profile or production of some aspect of musical events, such as their volume.
