At least in Bidule the delay parameter for Allpass
is measured in mS.
In freeverb the range is from 5 to 15mS.
As I understand it, it's intended to be a way of having a delay
with feedback, but arranged so that there's no comb effect on

Just meant that different frequencies are delayed by different amounts.
(Allpass is also used in a phase fx.)

sorry, I took your description below to mean that there
was a "loop of allpass filters".
