The reason that Casio style sites can't be found is that Casio is new to the upper end arranger market. Arranger styles, support, and sharing are all demands made by end users. Until recently, Casio's keyboard marketshare was simply low end keyboard techno toys so the number of end users demanding support and arranger styles is infinitesimally and unprofitably small.

If the MZ2000 takes off, and if Casio values and fills customer needs for additional styles, then its only a matter of time before their end user customer base will grow large enough to begin message boards, style sharing, style conversion and the rest.

But for now, they can't compete with the big boys. If you buy an MZ2000, then you get what you get at purchase time and that's it . . . forget about getting more styles until Casio sells enough units to make their arranger style market profitable (and that could take a very long time).

The best you can hope for right now is that someone can figure out how to convert other arranger styles into Casio's MZ2000 format so you can use them. Of course, Casio could throw a lot of money into developing a huge base of arranger styles and support in the hopes of luring customers from other manufacturers. But customer brand loyalty (as seen on Synthzone) makes this highly unlikely.

Probably the best marketing ploy Casio could make right now would be to develop a style conversion program that handles most of the available formats and simply give it to all of their MZ2000 customers for free. That would relieve Casio of immediately having to develop styles for a tiny unprofitable market and help satisfy customers at the same time.

Sorry, but I've been in marketing and technical communication for the past 25 years, and this is just the way it is . . . its just business.
