There are some times when you have to know the sample rate beforehand,
especially in delay situations where an algorithm depends both on the
milliseconds of delay AND the actual number of samples. This can
happen in reverb and filter design, and elsewhere. Otherwise this is
also a problem in more obvious ways when you're playing sound files --
sometimes I'll make my patches so that if it detects the wrong
[samplerate~] it tells the user to close the patch and fix it.

Which reminds me: there used to be a problem with [delwrite~] where it
would allocate its memory when the patch containing it loaded, based
on the sample rate active at the time, such that if you switched Pd to
a higher sample rate after the patch loaded, you'd have the same
maximum number of samples of delay, but not the same maximum
milliseconds. I remember there had been talk about fixing this, but if
it's still a problem, this might be a reason not to set sample rate
from the patch.
