Just messing around a bit.

Added a zValue input, to Wayne's multiProcess node.

The Arithmetic progression changes the zValue(s). There are 10.

The radius Slider changes the radius.
Also, the radius is adjusted by being combined with "geo" slider to progressively change the Factor of the Geometric progression, so the radius changes along the 10 cross sections in a curve. (Or not curved, depending upon values...)

The sqfactor Slider just changes the sqfactor from round to square.

The Loft mysteriously changes the loft color to default black, which looks white.

These are just experimental settings and combinations.
