I bought it along with four others (including the first BigTone analog bank) and when selected in the browser, it has the same sounds as BigTone Basic vol 1, with maybe a couple of exceptions.
I suspect a corrupt download, but I don't even see volume 2 in my user area to redownload (and while we're here, downloading volume 1 gives me a corrupted zip file).
And the BT beffy funk bass patch is a semitone sharp.
Looks like I'm not alone in being on the receiving end of the company's QA problems, but maybe someone has a quick fix?
