Why dont you just export the GP file to midi and import it into cubase?
Ohh, you actually want to read the tab as you go along?
Lol tbh dude, IMHO youd be better off just learning all your stuff thoroughly or printing out the GP tabs.
I'm glad I'm not the only one who does this.
If you play lets say 7fret A string, Cubase/GP will change that to 2nd fret D string.
