GbmanN gingerbreadman map chaotic generator


GbmanN.ar(freq, xi, yi, mul, add)


freq - iteration frequency in Hertz

xi - initial value of x

yi - initial value of y


A non-interpolating sound generator based on the difference equations:

xn+1 = 1 - yn + |xn|

yn+1 = xn

The behavior of the system is only dependent on its initial conditions.

// default initial params

{ GbmanN.ar(MouseX.kr(20, SampleRate.ir)) * 0.1 }.play(s);


// change initial params

{ GbmanN.ar(MouseX.kr(20, SampleRate.ir), -0.7, -2.7) * 0.1 }.play(s);


// wait for it...

{ GbmanN.ar(MouseX.kr(20, SampleRate.ir), 1.2, 2.0002) * 0.1 }.play(s);


// as a frequency control

{ SinOsc.ar(GbmanN.ar(40)*400+500)*0.4 }.play(s);
