no, i don't see any rounding errors...

it's generally a good idea to tell [delwrite~] how much space it should
allocate for the delayline. e.g. [delwrite~ abcd 1000] helped a lot...
and [rzero~ 0] is not the same as [z~ 1].
the output of [z~ 1] is y[n]=x[n1]
according to [rzero~]s helppatch it does the following:
y[n]=x[n]a[n]*x[n1]
since you set a[n] to "0", you just get y[n]=x[n] :(
to get [z~ 1], do something like

++
 
 [rzero~ 1]
