The developer has been on the forum and if you do a search you'll probably find various references. If you listen to the two solo banjo demos, I think you'll be impressed, as I was. In any case, I've been using it now for the past couple of days and I'm very happy. It's quite convincing!
It's a very nice sample. Nicely mapped with the open G-string, too, for easy realistic pattern playing. It's a bit different in perspective than the Bardstown Banjo as well, which makes it possible to use them both and get the feel of two different players. I have found it immensely useful, and the price is definitely nice.
