Hi Rikki,
well it was only outlined because harmony theory was really outside the remit for the intended readership.

you can input Steinberg Styletrax by changing group input to software arranger in the 32 bit version, but that input group has disappeared from the latest update. I believe the save was mentioned as the next module update, but tyros, pa80 etc conversion took precedence first for release, so mail EMC to be sure of status, it depends on the version.
