Hello there, 
    
I noticed that pd handles delayed feedback loops a little bit
      odd. Feedback loops seem to be only allowed within the sub patch
      that contains the delay as well. When I patch the feedback loop in
      the parent of the patch that contains the delay, pd complains with
      the usual error message and doesn't give me audio output. 
      
      The screenshots below illustrate the issue.
      
      
      
      No problem in this case. Everything fine. 
      
      
      
      I would argue this patch is functionally equivalent to the one
      above, but it refuses to run.
      
      Is this behavior intended?
      
      Best wishes,
      Clemens Wegener
