Notion rewire with Reason

Hi all.
I'm trying to make the Notion 3 demo work as rewire host with Reason. My need is mainly to use the Notion score editor with Reason sounds. Now...
you can do that? I followed the tutorial but I didnt understand how to send MIDI from Notion to Reason (I just managed to send audio back, from Reason to Notion).
Thank you.
