This may seem like a silly question, but is there some way to tell which version I have installed, pd-vanilla or pd-extended? I installed it from the Ubuntu repository, and the help screen says "Pd version 0.42-5". Does this mean I have the vanilla version?
The reason I'm asking is because I was going through the documentation browser in the help menu, and when I tried to open some of them (for example, rev3~ or complex-mod~), I get an error message "... couldn't create". I don't know if it's because it's not installed properly, or these objects only exist in pd-extended (and I only have pd-vanilla). Or maybe they've been removed but they were left in the documentation?
On a broader note, why are there two versions anyway? Why not just have pd-extended and forget about pd-vanilla? Just curious...
