There's a pretty good guitar pro file around somewhere. Includes all the keyboard parts. You should get guitar pro, most handy for learning stuff! (I work with GP 5.2, I've seen GP 6 briefly and it didn't look very suitable for keyboard stuff but I can very well be wrong there. GP 5.2 is guaranteed a good tool)
GP6 has a lot more options than 5, but is also far more confusing. It does have some nice keyboard options, but they're quite limited unless you want to pay for more sound banks.
I couldn't even find the keyboard view in GP6. Also I loaded some keyboard-heavy songs I made in GP5 into GP6 and it all sounded like shit. Might be the computer (not mine) not supporting midi maybe or whatever, I don't know exactly how all that stuff works.
