If DSP is on, you get a bang. If it's off, you won't.
Yes, that's pretty much expected, I guess. After all, it's not [savebang] ;-)
Perhaps [r pd-dsp-started] should only send bangs when dsp starts or stops, and not when the dsp graph is redrawn.
When the DSP graph gets rebuilt, DSP *does* stop and start (again).
even though I do understand that, for a tiny moment, the dsp needs to be off behind the scenes
It doesn't matter how much time passes between stopping and starting DSP, the point is that the DSP graph has or might have changed and "pd-dsp-started" will report it.
If, say, you want to send one and only one bang to [switch~] so as to graph tables when DSP starts
What do you consider a "real" start of DSP?
Actually, I'm rather asking myself whether it's necessary that saving triggers a rebuilt of the DSP graph...

So, If I am expecting a bang because I saved and DSP is off, it just bugs me that no bang is sent :)
If, say, you want to send one and only one bang to [switch~] so as to graph tables when DSP starts, then [r pd-dsp-started] is only useful if you spigot-out future bangs/saves/etc, otherwise you are graphing tables on every save...
It's a feature if you use it for randomness, say, to randomize seeds according to when dsp on/off switching or graph redrawing falls, say linked with a [timer] object :)

In any case, I think it's the misnomer what's confusing me. I realize that saving redraws the dsp graph, but I don't see why the dsp would "start" if it was already switched "on", even though I do understand that, for a tiny moment, the dsp needs to be off behind the scenes.

(a [metro] will also send bangs while patching, and yet it is useful in live-coding contexts.) gmsdtr IOhannes _______________________________________________ Pd-list@lists.iem.at <mailto:Pd-list@lists.iem.at> mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list-- fdch.github.io http://fdch.github.io
