This distortion is inspired by electronic circuits that use polarisation points of non linear components.
Here, I use an hyperbolic function "polarised" around 1 with a controllable "factor" (that controls the non linearities):
Low factor => almost linear, nice for modelling old amps:
Mid factor => nice dissymetric distortion
High factor => pulsy, level detector distortion
note: all graphs plotted on Wolfram Alpha
Note that gain and range are automatically modified so that this distortion takes a full range signal and outputs a full range signal. It makes it convenient when used with sine generators and Phase Modulation to add a somewhat "analog" color.

This distortion is antialiased by differentiation, much like the good old DP (differentiated polynomials).
generalisation of the differentiation method to rational functions. Very nice distortions can be done with these.
