normally you will not have block-delays.
so chaining 2 or 1000 [hip~]s will give you exactly 0 samples delay.
block-delays appear only in very special cases, e.g. when using
there is some documentation about how to avoid this in

no. (see above)
i am *very* sorry that i ever introduced this stupid [nop~] object that
does delay the signal by one block.
this should be considered a bug!
probably i'll change the behaviour in future versions of zexy to a real
[nop~] (which does exactly *nothing*)
i guess a lot of confusion about block-delays might come from the wrong
behaviour of [nop~]
