Biab is not designed for covers but if you take the time to learn the stylemaker and stick to midi only you can do a lot with styles assuming you have a good quality midi synth. Example, write your own style that uses that bass line. But and it's a big butt if that's what you want to do is to produce covers then imho you're much better off just finding, buying or creating midi files. You would play and edit those in Real Band. There's websites that sell really excellent ones or you can find some good ones floating around the web. The only thing with those is you never know what you're gonna get. They're free, ya know? You can also check out Norton Music, Bob Norton posts here all the time. He's created and sells hundreds (thousands?) of styles that suit a lot of covers.
