LatoocarfianL

A linear-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 * y[n]) + d * sin(a * x[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). NOTE: This UGen is experimental and not optimized currently, so is rather hoggish of CPU.

===Examples===

// default initial parameters
play { LatoocarfianL.ar(MouseX.kr(20, SampleRate.ir)) * 0.2 }

// randomly modulate all parameters
play {
 LatoocarfianL.ar(
   SampleRate.ir/4,
   LFNoise2.kr(2).mulAdd(1.5, 1.5),
   LFNoise2.kr(2).mulAdd(1.5, 1.5),
   LFNoise2.kr(2).mulAdd(0.5, 1.5),
   LFNoise2.kr(2).mulAdd(0.5, 1.5)
 ) * 0.2
