If that is your simple question and "Assuming by composition...I mean the straightforward recording of backing tracks that are good enough sounding to put out commercially, not necessarily on a CD though."

The answer is clear..... Yes you do. As a composer that uses BIAB, you will find these Xtra Paks essential over time. The versatility of BIAB depends solely on the amount of content you have to work with. The core BIAB program is the same across all versions.
