10.1 Engine Math

BigBob did an outstanding job with his math library, which has been used extensively by any developer so far. Thanks to the new real math routines that come with Kontakt 5.6, it is possible to enhance the precision of those calculations, as well as reduce drastically the amount of lines of code required to convert an Engine Parameter into a linear value and vice-versa.

All these functions are inline functions, therefore can be used in if statements and loops.
