Had to recap on work done in February – wasted time figuring out that the pathwriter player wouldn’t work on Linux because i didn’t have the libraries installed in the right place – this will need sorting out – more follish was a hour spent looking for a solution because forgot that a double click was required to trigger the glist not just a single click.

A managed to get the example gem/pd file to work for presence detection – chapter 5 of Chung’s brilliant book https://www.packtpub.com/gb/hardware-and-creative/multimedia-programming-pure-data
