both examples are mono synths that use simple signals as inputs for the distortion.
These object use integro differential anti aliasing of rational functions (a polynomial divided by another polynomial).
I experimented with many analytically integrable rational functions and i chose those that do not have tan nor log. Here are two functions that i found quite interesting.
Here is "type II A".
the distortion function "type II A"
Here is "type II B": is almost the same thing that type II A but with sort of crossover distortion as found in some push pull transistor amps.
Combination in series or/and parallel leads to interesting results...
