cauchyi — Cauchy distribution random number generator with interpolation.
Cauchy distribution random number generator with controlled interpolation between values. This is an x-class noise generator.

kalpha -- controls the spread from zero (big kalpha = big spread). Outputs both positive and negative numbers.
For more detailed explanation of these distributions, see:

xamp -- range over which random numbers are distributed.
xcps -- the frequency which new random numbers are generated.
Here is an example of the cauchyi opcode. It uses the file cauchyi.csd.
