Hi! Once again I'm asking about the allpass filter. I am trying to do it using a delay a feedback and a feedforward as it is shown in the diagrams of most books. However, I am not sure I've my patch is ok since so far I have three versions and I am not sure which one is right. Could someone have a look at this one for me?

Thanks!!!
