object GbmanN extends Serializable

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

x[n+1] = 1 - y[n] + abs(x[n])
y[n+1] = x[n]

The behavior of the system is only dependent on its initial conditions. Reference: Devaney, R. L. "The Gingerbreadman." Algorithm 3, 15-16, Jan. 1992.

Examples
// default initial parameters
play { GbmanN.ar(MouseX.kr(20, SampleRate.ir)) * 0.1 }
// change initial parameters
play { GbmanN.ar(MouseX.kr(20, SampleRate.ir), -0.7, -2.7) * 0.1 }
// wait for it...
play { GbmanN.ar(MouseX.kr(20, SampleRate.ir), 1.2, 2.0002) * 0.1 }
// as a frequency control
play { SinOsc.ar(GbmanN.ar(40) * 400 + 500) * 0.4 }
