Logic Pro X - Multiple MIDI Tracks to one instrument (Track)

Hi ...

I have imported a type 1 (Multi-track MIDI) to Logic Pro X .

All my drum-kit pieces are on their corresponding tracks .

I would like to send each of these MIDI tracks to Addictive Drums (and from there on / Addictive Drums send the tracks to their separate buses / aux) .

But I'm a bit lost here ... When I go to the mixer view I can't find a way to set the outputs of the MIDI tracks to the Addictive Drums / instrument track .

When I first imported the MIDI file the tracks that were created had a instrument selected by Logic .

Now, how can one create an empty / plain MIDI tracks for which to set the output from to Addictive Drums or some other instrument ?
