Greetings,
Just got GM3 and started hooking it up.
my setup - Cubase 13 pro/UA Apollo 6x TB/Windows 11
I did put GM3 as an insert into an audio track.
Then added an instrument track with NI Kontakt 7 Electric Mint guitar.
Then routed GM3 insert midi out into midi instrument midi in.
Don’t see any midi activity in Kontakt instrument or Cubase MIDI out monitor.
I must be missing something trivial.
Thanks a lot.
Did you enable “monitor” on the Kontakt instrument track?
This is how Cubase shall look like. Use the MG3 “MIDI Guitar Mini” patch. Insert the MIDI machine “Transposer” and set it to + 1 Oktave since the “Kontakt Session Guitarist Series” requires that in order to match the pitch.
Thanks a lot for your pointers! All is good now, sort of 
Main issues are: lagging but I saw one on YT addressing that, and glitching that is beyond being passable. Spending the weekend watching all tutorials. Besides growing pain, the soft looks unbelievably sophisticated.
