i got this annouying guitar pro bug, cant remember how i used to fix it

basically if i change the tuning on an instrument, usually its to C standard, after changing tuning the onscreen keyboard doesn't move the notes, aka say i got a C note, the score shows it as C, the fretboard shows it as C, the onscreen keyboard shows it as E

any ideas people?

every note is shown 4 semitones higher on the onscreen keyboard than what it should be
