Yes. Pd extended also had something like "all about arrays", IIRC.

I honestly get lost in most of the internal messages and forget which 
ones are "public" and which aren't.

To be fair, "pd-dsp-started" / "pd-dsp-stopped" are not mentioned in the 
change log. I also discovered them by accident (probably from reading 
the [samplerate~] help patch).

It would be cool if there was a central place where all (public) Pd and 
canvas messages are documented. The canvas messages are especially messy 
because they are currently split across several help patches and 
examples...
