I just created a Bass track to test this, but when i get to the tuner in game, I have the following problem: the tuner says my bass is tuned an octave too high, while it's not. I need to play the song on my 5-string in the Bb Eb Ab Gb tuning. I'm now wondering what i did wrong... If you're interested: the song is Come to life by Alter Bridge.
