object StandardL extends Serializable

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

x[n+1] = (x[n] + y[n+1]) % 2pi
y[n+1] = (y[n] + k * sin(x[n])) % 2pi

The standard map is an area preserving map of a cylinder discovered by the plasma physicist Boris Chirikov.

Examples
// vary frequency
play { StandardL.ar(MouseX.kr(20, SampleRate.ir)) * 0.3 }
// mouse-controlled parameter
play { StandardL.ar(SampleRate.ir/2, MouseX.kr(0.9, 4)) * 0.3 }
// as a frequency control
play { SinOsc.ar(StandardL.ar(40, MouseX.kr(0.9, 4)) * 800 + 900) * 0.4 }
