yes, the dsp chain is recreated ...

sure ... the more complex the dsp graph gets, the cpu time to resort the
graph increases ... of course allocating memory from the underlying os
is not a lightweight operation, either ...

in pd, you shouldn't try to resize / load / store tables during a
performance, except you like the sound of the audio dropout ... if you
need this, i can only suggest to use another program ...

Most of the trouble in this world has been caused by folks who can't
mind their own business, because they have no business of their own to
mind, any more than a smallpox virus has.
