Ahem, just to make it clear, I have a 1992 psr410, so i don't think it have any kind of format to save... My idea is to plug the keyboard to the computer, press "play" on the keyboard and "rec" on the computer midi program, and arrange all to the format of the casio rythm system.... I know it isn't as easy as it sound, but that was my idea... In any case Alex, yes, I will be very grateful if you can get me those styles. Don't hurry, please, I still haven't got my new keyboard...(well, I'm still not even decided on it at 100%)... In any case, they are "Disco Pop", "Pop Shuffle" and "FolkRock". By the way, is any way to play ac7 files on pc or android. Thanks to all for your answers.
