Hi Jokeyman, I am a real ignoramus, I think P M stands for private message, but don"t know how to do that.But very curious to know how you could send me the whole version by email.Just to recap the interface instructions shows the piano connection using midi cables, but the Casio does not have midi cables only usb. The salesman sold me a cable with 2 t s 1/4 plugs on one end and a sterio mini jack on the other and said I should plug this cable into the 2 sockets on the front of the interface and the mini jack into the headphone socket of the casio those sockets are marked mic. and instruments and that puzzles me. a number of guys have said I don"t need midi cables and so I am totally confused
