Bass Tab Music

What is a good download for bass tabs?

I don't know the name of the thing I'm looking for. =/ I needed to find this kind of Application Download thing for the computer that lets you put the notes in and they can play it back and such. Does anyone know what I'm talking about? Lol. And if so, do you know a good site for it? I need it to be FREE. =P

3. Guitar Pro is great, but it's too expensive, $60 I think. Get the trial version (you can't really print with it), if you like it, buy it. I play guitar and I use it al ot, Ultimate-Guitar has a lot of tabs for full songs, including the bass. Hope that was helpful, good luck.
