PD is back!
After a few days wondering what I was going to do about pure data not being in the lucid repositories, Peter (Vasil) pointed me in the right direction.
He told me to look here
Just be sure to open the .deb package in the right way and it will install pd on your machine.
The next thing I had to remember was that instead of invoking it with $ pd& in the terminal, it is now $ pdextended&
Haven’t had a chance to play much, what with the Leipzig project, but will happy to have it back!
