Hey,

but I still needed an example to see how to make this happen :) 

Attached you find a simple example for recording N ms of sound to disk.

that's used n the help file of [samplerate~] but I agree it should also be included in this new documentaton section. Anyway, what else would you use it for?

It's useful for preventing "angry vline~s": if you accidentally keep sending messaes to a [vline~] while DSP is off, it will eventually bring Pd to its knees. The solution is to use a [spigot] which is opened on "pd-dsp-started" and closed on "pd-dsp-stopped".

Actually, the issue should be mentioned in vline~-help.pd, together with the possible solution.

Great, kind of what I was expecting, but I still needed an example to see how to make this happen :)

My use case was that I had a patch which either produced some generative
music or processed some soundfile and I wanted to record N seconds as
fast as possible. It's basically like the render function in a DAW
(usually you don't have to start the DAW from the command line to render
your project :-).

I also thought about that and I'm really excited to test both things. Hopefully I can have an example of this in my tutorial rght now and release an update. But my attempts here failed and froze Pd :) 

Have you already messed with it, Christof?

 

But I agree that this needs to documented. Generally, there should be a
section to document all (public) Pd messages, like [pd dsp(, [pd quit(,
etc. (What can be considered "public"?)

I opened an issue for that ( https://github.com/pure-data/pure-data/issues/1125 ) and can take care of it as I'm usually handling documentation issues.

 

Also [r pd-dsp-started] and [r pd-dsp-stopped], which most people don't
know about, I guess.

that's used n the help file of [samplerate~] but I agree it should also be included in this new documentaton section. Anyway, what else would you use it for?
