I am working through the [http://www.pd-tutorial.com/english/ch02s02.html](link url) and on "18.104.22.168.10 Demultiplex" it shows that there is a "demux" object, but I can't make it work, it just doesn't become a proper object with inlets and out lets, just the usual dashes to show its not recognised as an object.
Why would it be in the tutorial and not work in the program itself.
Also I thought I had installed "pd-extra" but now I can't find it in "synaptic package manager".
Can any one help?
