OK, I got it now.

If you can read Japanese, go to www.ymm.co.jp or view it through an on line translator.

They publish a lot of things for the electone series, including registration disks, song disks and books like this:
http://www.amazon.co.jp/dp/463682317 6/r...76&linkCode=asn

It is probably a kind of arrangement written especially for the Electone and then played back with the aid of regisrtations and background song data.
