What is the digital course latch plate?
Another difference I noticed is 70 more tones (670 versus 600). There are no demos up yet, so we'll have to wait and see if any of the samples have been changed. It would have been nice if USB MIDI had been in addition to DIN connectors, but it seems that it has replaced them, as best I can tell from reading the online info. From the brochure I downloaded, the rhythms have been revised, the SD memory can be up to 1GB, and the expected release date is October of this year.
If I determine what a "digital course latch plate" is (other than a victim of poor translation), I'll let you know.

EDIT: Okay, I think I know what "digital course latch plate" really is. I looked at the Casio online info, but the versions in other languages. The phrase, in the Spanish version, is "barras de desplazamiento digitales", which translates to "digital displacement bars". In French, it's "les tirettes harmoniques numériques", or "digital harmonic pull-knobs". Hmmm, beginning to make sense. Then in German, "digitale Zugriegel". Well, among a few possibilites, "Zug" can be "draw", and "riegel", "bar". So "digital course latch plate" should apparently be "digital drawbar(s)", which of course these Casio models have for the organs.
That's the best I can do, but I'm not a native speaker of anything other than English; if anyone has a more accurate translation, please speak up.
