Because I'm a guitarist, but right now, I'm tabbing out a song that I'm trying to learn on the piano. And I've got the left hand good, but the right hand is playing the sames notes in the same octave.... If you understand what I'm saying can you please help??
Go to menu Tools->Transpose to transpose the track (12 semitones up or down). Be careful with "Apply to all tracks" option. Or if the problem is in sound only, not in notation, then Double click on track name and change Offset (-12 or 12 as you need).
