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 :)
Perhaps [r pd-dsp-started] should only send bangs when dsp starts or stops,
and not when the dsp graph is redrawn.
