First, an apology: indeed the pd help and examples are lagging. We keep a strict vanilla-pd discipline and that makes the translation of code quite more involved… including having to code our own 2d plotter and such niceties.
Second, for example code, our YouTube max tutorial series have accompanying patches, and these have been translated. I attached them here, and they are less documented but with the tutorial you should be able to follow.

I hope this helps a bit, and stay tuned for more stuff in the next month or so
