You're welcome. I didn't describe OBS functionality. I gave credit to smittefar as that may be a solution.
Regarding Guitar Pro, it does work as I described.
Worst case, if you don't want to or can't seem to configure your setup. First, just record the audio file using GP into the daw using USB 1/2 default...bounce the recording to another channel. Now record using fractal against the daw recording while recording the new track. You're just not playing to the song from your GP software, it's playing from your DAW...then record the guitar track.
I use Windows, but I don't use Fractal USB for audio. USB is only used for Axe Edit.
