Hi Sam. As said, Sibelius is a notation program. That might be all a songwriter needs; it depends on who is using it and how they prefer to work. But it certainly is not an accompaniment generating program in the sense BIAB is.

I don't find Sibelius particularly easy to use, and prefer a few other notation programs, but many professional musicians like Sibelius very much. Sometimes it all comes down to which one you learned first.

Also, if you are planning on purchasing Sibelius, be aware all the programmers were recently fired in the takeover and its future is in question.
