Maybe, but Guitar Pro works great for me and can also be had relatively cheaply.
I'm currently downloading the new RSE packs, the servers seem really slow so this is going to take ages.
One question: Guitar Pro is supposed to have a chord finder, right? If yes, can someone tell me how to activate it? Most tabs/songs don't seem to have chord symbols which is a bit annoying because I always have to look at the guitar notes to find out exactly what chords are being played.
