that tabread4~ might be a little less processor hungry. Anyone have any clue?
nothing(!) is faster than reading values from a table. you have very little overhead by getting the input signal to the correct range, and a bit more by the interpolation of [tabread4~] but still, reading tables should be ways faster.
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~]
