Thanks Bernie and Bill.
Yes you're quite right Bill, I do have a rather 'posh' Hiyatek Multicard reader/writer and hadn't thought about trying that. The card reader I was referring to is a tiny thing shaped a bit like a tree, wide at the SD End and narrow at the USB end. It is so small you can get it in your purse - that's why I was interested.
Bernie, your comment on the files being midi format makes sense because I know the member who used it got it from his friend who is a 'singer' using mainly 'backing tracks' on his Tyros 3.
Changing the subject Bernie, I see you have the Audya - what do you think of it? I'd be very interested to know as I heard it played by a young lady at a holiday camp and was impressed. She usually plays the KN7 so I was surprised at the change. However 4 months later, she was back with the KN7 and when I asked her about it she told me, the Audya was "too complicated" ?
