I have a couple of other reasons why it would be good to keep the 'old'
filters:

--  they are of historical significance. 'tone' and 'reson' are
described as such in all the literature from at least Dodge and Jerse
onwards.

-- they are relatively simple - which mean that dsp innocents like me
have a batting chance of understanding them! The code is not only
functional, it is very educational.
