<< So bbw is different to bbw4 bbw2 ? >>

Even though they are all 74 megs, it seems they are different.

Open this MultiStyle in BIAB and as shown in the screenshot below, it opens with 16 sub-styles.
Open that same SGU file in RealBand and in the screenshot below, it opens with only two Sub-styles.
EDIT: Open that same SGU file in Standalone Plug-in and it opens with only two Sub-styles. (I just tried it and that's the result I got)

I don't know if the bbwxxx files are the algorithm or not, you seem to think they are and that's fine, but as I stated and demonstrate below in the screenshots, the various programs don't share the same algorithm. BIAB algorithm is far more advanced, complex with more functions than what's featured in the lite versions offered in RealBand or the Plug-ins.
