output~.pd is comes with the examples but I put it in anyways because I would use it a lot in diagrams that I want to add a volume control.
queue.pd and stack.pd require the coldswitch.pd to work properly. If you want, you can look at the diagrams for queue.pd and stack.pd and see that there are too many lines are crossing each other.
Please make comment of it.
