I use Logic by Apple. It does everything Guitar Pro does and about 100x more.
I use it as a practice tool and play along with tunes I picked up off of the
Internet (typically in MIDI format). What I particularly like about playing
with Logic is that the score/tab scrolls so you're always centered on the
correct time in the music. Guitar Pro goes left to right, left to right, etc.,
until it gets to the bottom of the screen and you don't get to see the
note on the next screen until it is already playing.
Plus, Logic lets you record music and compose music with thousands of
great instruments and loops.
I do have to give Guitar Pro some praise, too. Where it really, really
excels is in the fact that there are tens of thousands of tunes created
for it. You can find tons of music for Guitar Pro. What I do is open
the Guitar Pro files and export them to MIDI files where I can read
the in with Logic.
Logic Express (all you'll probably ever need) is $199.
Logic Pro is $499.
