I want to purchase BIAB but I want to make sure first if it's for me.

I am planning to write songs but since I only play guitar I'm hoping that I can use BIAB to do the other instruments.

I want to be create my own style for my music. I know that it has a style wizard which will allow me to create my own style. And hybrid style which will allow me to combine different styles.

But how good really is the style wizard? If I learn it enough and I want to create lets say a Red Hot Chili Peppers type of bass and drums for my own original song structure and chord progression. Will this be effective? I have all the midi files needed but I don't know how well BIAB will adapt to these midi files and how effective it will be in song writing.

Thanks guys in advanced :)
