Is it because [line~] reaches 1 for a little time before being reset to 
0 ? Thus when multiplied by the number of elements, it generates an 
out-of-range index, used several times. Combined with a cos(something) 
that doesn't give exactly zero anymore (because the out-of-range can last 
up to 63 or 64 samples), this might allow the click to be heard ?

(I haven't thought about it in detail, though.)

BTW where is the corrected patch that you said you made using [phasor~] ?
