Ableton=Master; Notion=Slave; Now it works!

I want Ableton to be master and Notion to be slave. I wished Notion turned every loop from ableton, while i edit the notes in Notion. That´s what i´m thinking about.
In the Ableton-Audio-Track for taking back the audio of Notion i can find Notion. OK.
In the Ableton-Midi-Track for taking the Midi-Information from Ableton to Notion (MIDI TO) i can not find Notion. I aint not transfer Midi-Notes to Notion, but there must go MIDI-Clock-Information for telling Notion when to start, when to stop and where in the Score it has to play from Ableton to Notion. Maybe it is not nessesary to build a Midi-Track for "MIDI TO".(?) So what is nessesary for connecting Ableton with Notion in the way i discribed?
What goes wrong??!
