But all waveshapers also do change the spectrum according to the volume 
(except those that are linear, which basically means those waveshapers 
that are configured to do nothing.)

Perhaps you mean the manner in which this effect does the change of 
spectrum ?

I think that the sounds are often quite similar to what [expr~ sin($v1)] 
does, which is quite normal if the input data is rather sinusoïdal. Yet 
those are distinct formulæ that behave differently from each other in many 

Try various filters before [vd~] (but not affecting [delwrite~]). I mostly 
tried [rpole~], [lop~], [expr~ tanh($v1*$f2)]. Actually, I add them before 
I rescale the delay to the range 2<y<2+2n. (Be careful with hard clipping 
if you use things that have a gain, such as [rpole~] and obviously [*~]).
