I have my track routing correct, and it only seems to be Reaktor that REAPER is passing a dry signal through in addition to the reaktor processed audio. Not sure if anyone else has had this experience and knows how to fix it. thx.
Fixed, found an old thread, need to use VST and not the VSTi for some reason. Does anyone know why?

to expand on what paule said, reaktor figures that the only time you don't want the original audio passed through is when your process is an effect on the original audio.
VST = VST fx
VSTi = VST instrument
Makes no difference, Reaper uses all other VSTi with audio inputs fine.
