My old friend Dikki used to say that the main thing that sells arranger keyboards is styles and sounds. Other features , whilst important are not essential.
So far Casio have focused on features with their marketing .....
I wish them luck with that strategy.
I think all the typicall keyboard sounds (piano/dp/organ/synths/strings/pads) are top knotch... And thats where Casio has been concentrating its efforts from a stage piano kind of view..
Styles? Well, it plays yamaha styles, so there is a huge colleection to sattisfy everyone.
But indeed they have been concentrating on features... In their marketing... Probably because they think thats what sells arranger/workstations hybrids...
Still early but i do believe in the end this instrument might archieve cult status for its innovative features among people that want to create their own sounds...
