Lenovo worked!! So thanks much. Still have not given up on connecting the Privia to my iPad 4. I contacted Casio tech support and they confirmed that I can't go in through the MIDI -USB as it is not MIDI class compliant; they suggested finding a way to connect from 5 pin MIDI port to the Casio - not sure how to do this, saw Line6 MIDI Mobleizer, wonder if anyone is familiar with it and it works for this purpose. Thanks
