That's the basics. Some other things you can do are:
1 Colour the audio tracks and hide the VSTi track in the Mixer:
- select the tracks, right-click and select untick "Set track colors to one random color",
- select the VSTi track, right-click and untick "Show selected tracks in Mixer",

- in the FX window, click [Options] and select "Build 16 channels of MIDI routing for this track"

This would be the current Routing panel for the VSTi track:
- you will see that the track now receives MIDI Input from each of 16 tracks,
- note that all the MIDI received on each MIDI track is sent to a specific channel for that track.

3 Manage the MIDI tracks:
Put the MIDI Tracks in one folder, name the folder, colour the tracks and hide them in the Mixer,
- insert a new track before the first MIDI track,
- click the folder icon once to set that track to Folder Start,
- insert a new track after the last MIDI track,
- click the folder icon once to set that track to Folder End,
- double-click the folder track name and edit it,
- select all 18 tracks, right-click and select a track colour,
- right-click again and untick "Show selected tracks in Mixer".
4 Enable Keyboard input for the MIDI tracks:
- click the Record [R] button on the VSTi track to turn it off,
- select all 16 MIDI tracks,
- click the Record [R] button to expand them,
- click the Recording Monitoring button to turn on Input monitoring for all 16 tracks,
- for each track, set the MIDI input channel, from 01 to 16,
- click the Record [R] button again to collapse the tracks.

5 Manage the audio tracks:
- put the audio tracks in a second folder, name the folder and colour the tracks,
- colour the Folder Start track differently to make it distinct in the mixer,
- hide the Folder End track in the mixer.

6 And finally:
Save the tracks as a track template.
7 Here I have enabled for Recording MIDI channels 1 and 3 only. In Kontakt the instruments are routed to its mixer channels 1 and 3, and from there to the track's channel pair 1/2 and 5/6 and thence to tracks 21 and 23. I have also collapsed both the MIDI and Audio folders in the track control area.
