in Bifurcator the current output (and initial "load value") ranges from 0 to 65535, which maps directly to _x_ in the range 0.0 to 1.0. the parameter ranges from 0 to 65535, which maps directly to _r_ in the range 2.0 to approximately 4.0.
the first value of _x_ is set with the **load value**. it must be set to a non-zero value, otherwise the next iteration would also be zero... and the next one too... and so on, generating silence. default is 1.
by varying the parameter, the values of _x_ may change drastically, producing a variety of sounds. the higher the parameter, the more "chaos" is present, effectively yielding noise.
for most parameter values below 32768 the output converges to a single value (effectively no sound).
above 32768 the output starts to oscillate. from 32768 to 47496, it bifurcates to oscillate between between 2 values, generating a square wave. from 47497 to 51433, it bifurcates again and becomes a period of 4 values. beyond that, the system rapidly becomes chaotic (noise). there's an "island of stability" starting at around parameter value 59914 where the output oscillates between 3 values, then bifurcates from there.
