However, speed put aside: If you want to change the waveshaping
function on the fly, then you're stuck with arithmetics as changing a
table's content is generally a no go in Pd in this use case. There are
some special externals for Chebyshev polynome based waveshaping. I did
shabby~ and shaffy~ but they are crude and even I don't use them
anymore, the better one is in Tom Schouten's collection of creb and
called [cheby~]
