actually this is very complicated to answer.
when i write externals i have 2 choices for messages to externals:
1) something very simple; e.g: a "float" message to a [f] does really
what i would expect it to do
2a) e.g: gem-objects respond to a "gem_state" message; this has been
true for years and i don't see a reason to change this - so every new
gem-object will respond to a "gem_state" message too
2b) when extending the functionality of an object, sometimes you come to
the point when you say "oh, why haven't i thought before! \"set\" would
be an ideal message for this functionality but unfortunately it is
ad 1) there are two things one could do about it: learn the pd-language
and read the help-patches
ad 2) convention is the daemon that is lurking everywhere in pd. by
convention signal-objects end with a "~", by convention
max-compatibility is not broken willingly,...
ad 2a) who is to blame ?
ad 2b) and who is to blame here ? it would be simple to change the
messages an object responds to (from a programmer's side of view), but i
try to avoid to do so because it would break each and every patch that
relies on an older version of the external.

basically pd's dsp-engine is not designed for this.
this makes it quite unusable to work with compressed-data with non-fixed
furthermore it only allows blocksizes which are 2^n.
indeed it would be a great feature to make the blocksize change
deliberately, but i do think that it will be a lot of work (and
performance is likely to decrease drastically)

i have heard about a love-patch that guarantees four inches.
