I bought a BS2 some months ago and there has been a problem with the A190 Midi / CV interface. The webshop where I bought it tells me to send back the whole rack for only one module ! Of course, by the time, I bought a few other cases and the former modules of my BS2 are now dispatched in those cases. I also bought some new modules in some other shops and they are now in my BS2. Everyday life of the noodleist I guess.
