Sounds like the randomness is propagating onto itself, crescendo 
and undulating. Very good.

Subject: Re: [Csnd] rand with cubic interpolation?

Hi Mauro,

I implemented a UDO for randcubic to generate bipolar cubically
interpolated random line with kamp and kfreq arguments.  The code,
example CSD, and audio example are available here:

Just a note that cubic interpolation can overshoot boundaries.

Hope this helps!
steven

I would like to generate a smoothly interpolated curve from the generated random points, instead of a step-style curve or a linear-interpolated curve... How can I do that?
