3.audio.examples/E05.chebychev.pd is the waveshaping example in
Miller's docs. 

The basic idiom is very simple and similar to how you build a
wavetable oscillator with phasor~ and tabread4~: You scale the
incoming signal by multiplying with the table size so that it spans
the whole table, and then use the incoming signal as an index to
tabread4~ which gives the output signal. The contents of the
wave(shaping) table are also called the transfer function.
