should have a look at "songs2see" with the editor you can use any of you own songs you have on CD, midi, etc, and play the bass in a game a bit like Rocksmith. you have the choice of other instruments like keyboards, sax, guitar, etc that you can use too.
I like Songs2see a lot better than rocksmith as it give you much more choice of the songs you can play, you can play in tab if you want too, its on steam and well worth a look! use what ever connection you want to the computer, I'm using a line 6 GX and it works great.
