Hi,
This is a GOP datastructures envelope generator. It requires Pd 0.39-2. You can bang the left inlet with a number of milliseconds and it produces whatever envelope you drew, as a signal stretched over the milliseconds you banged, and normalised, at the left outlet. You can use the right inlet to access specific bits of the envelope. The number box adds new points to the envelope, by default in the top right hand corner. Drag them somewhere else.
