Mathematical distortion and signal mangling

Version 1.0 is the accurate Faust reproduction of a VST plug-in I wrote in 2003. In later versions, I have modified the parameter ranges and added some new functionality.

This signal mangler features a weird kind of overdrive (see source code for exact formula), a hard-clip distortion, LFO-modulated bit reduction and the possibility of calculating the modulo of a signal. I have never heard anything like it, which is why I finally release it to the wild.

In case you choose to use the old version 1.0, be very careful! This thing gets super-loud faster than you can say "thingamajig"...
