I bought this keyboard a few years ago to learn about software music production. I did a few small projects with it and since then it has been sitting in the box, so it hasn't ever been used much. It is in great condition comes with the original box, USB lead, software and instructions.
Last time I used it, it worked perfectly. The mac I used to use it with broke so I don't have anything to connect it to anymore. If you would like to test it you may want to bring something suitable with you.
