I just realized on the Roland website that the BK-7m is no more listed, and when entering it in the search, it says 'discontinued'.
I really hope Roland is not so stupid to abandon this module without preparing a successor!
http://www.roland.com/products/bk-7m/ Very sad to hear that, unless, like you said, they're coming out with a successor. I'd love to see one with SRX sounds and even SuperNatural sounds in it. I'd be a sure winner!
