where you choose this?

Go to DEVICES > VST INSTRUMENTS > this should show you a screen with multiple slots that each say "no instrument"
Click on slot number 1.
See a list of the installed VST Instruments on your computer.
Under the "External" heading you should see "Motif XF VST".

Either way, please show us screenshot on your computer.

When you launch the Motif XF VST you are asked if you would like to create a MIDI Track assigned to the VST PLUGIN.

Yes, your screenshots are correct!!!! (My initial screenshot should have looked like yours... Sorry I cut and pasted "before" picture, not "after" picture... "Track Inspector View" screenshot is correct!!!)

When you play the Motif XF keyboard, what happens... ?
Do you see MIDI Activity on the MIDI Track?
Do you see keyboard on the Editor screen indicate the notes you are playing?
Do you see audio Activity in the Audio Lane?

No sound is a SAFFIRE issue, sorry, you must correct.
Connect headphones to XF ... you will hear audio.
Audio Activity in the Audio Lane means IT WORKS...

NO SOUND means problem with audio interface > Speakers...
