I wonder if anyone has thought about this?
I am aware that it may have little practical use and may actually worsen the
"fractal noise" behaviour at higher feedback levels.
(Long ago I tested this with a tuned delay in the feedback path and
thats what I recall)
But still I am interested.
If the recurrence for the oscillator with feedback is:
y[n] = ( 1/(2Pi) * sine(2*Pi* y[n-1]) + k) mod 1
there are two nonlinearities and it's all above my head...
