object HenonC extends ProductReader[HenonC] with Serializable
A cubic-interpolating sound generator based on the difference equation:
x[n+2] = 1 - a * pow(x[n+1], 2) + b * x[n]
This equation was discovered by French astronomer Michel Hénon while studying the orbits of stars in globular clusters.
Examples
// default initial parameters play { HenonC.ar(MouseX.kr(20, SampleRate.ir)) * 0.2 }
// mouse-control of parameters play { HenonC.ar(SampleRate.ir/4, MouseX.kr(1,1.4), MouseY.kr(0,0.3)) * 0.2 }
// randomly modulate parameters play { HenonC.ar( SampleRate.ir/8, LFNoise2.kr(1).mulAdd(0.2, 1.2), LFNoise2.kr(1).mulAdd(0.15, 0.15) ) * 0.2 }
// as a frequency control play { SinOsc.ar(HenonC.ar(40, MouseX.kr(1, 1.4), MouseY.kr(0, 0.3)) * 800 + 900) * 0.4 }
