Yeah, this has been covered here before. Look up DSP loops in the archives. In short, you can't ask a subpatch/abstraction/whatever to compute output based on it's input simultaneously. Unlike analog electronics, where electrons move almost simultaneously, in DSP it's logically impossible. So

There's two problems with your patch. There's a sign error in one of the expr which calculates the imaginary value. The second problem (in the same expr) was a * vs / error ( you put / 2*$f1 instead of / 2 / $f1). Does that make a difference? Anyway, I jiggled with it enough to get it right.
