Well, I just recently got this program from a friend of mine, .
It's called Guitar Pro 4, and though I'm not exactly a guitar person, it does feature a variety of percussion instruments that I'm more accustomed to. Also added, instead of a guitar neck to make notes, I can opt for piano keys instead. Put simply, it rocks. Before, I couldn't understand how the thing worked (Tab Trax was so much easier, but it was only a demo...) but now that I've gotten the hang of how to use the keys and commands, it's safe to say I'll be removing Tab Trax from my computer.
Heh, thanks for the program bro.
