[PD] Creating signal patches by messages

hi Miller,

perhaps, there could be a 'resetdsp' message to pd, or the message
'dsp' taking an optional second argument: ``do not touch audio
hardware'' flag ?

Btw, am I right, that all well-behaving tilde-externals should be
transparent to the dsp graph resorting, i.e. they are expected not
to reset their state.  For example a filter should not clear its
memory, etc?

I think, no tilde-internal in Pd resets state in its dsp routine,
unless the sr or the block size changes.  That is really great.
It is a different story in max (which is easy to check with the
tapin/tapout pair).
