LatoocarfianC : LatoocarfianN : ChaosGen : UGen : AbstractFunction : Object

Description

A cubic-interpolating sound generator based on a function given in Clifford Pickover's book Chaos In Wonderland, pg 26. The function is:

    x(n+1) = sin(b * y(n)) + c * sin(b * x(n))
    y(n+1) = sin(a * x(n)) + d * sin(a * y(n))

According to Pickover, parameters a and b should be in the range from -3 to +3, and parameters c and d should be in the range from 0.5 to 1.5. The function can, depending on the parameters given, give continuous chaotic output, converge to a single value (silence) or oscillate in a cycle (tone).
