Hi Philippe,
After having played the CT-X3000for two weeks, of which I really liked the sounds and styles (“rhythms” in Casio language), I found that the sounds and styles of the PSR E463 were not on par.
Unfortunately I haven’t had the opportunity to try the PA300.
I really hope that the PSR S675 will come out in the near future, or that Casio will release a keyboard with the AiX excellent chip and a more friendly user interface, maybe next year.
In the meantime, I haven’t decided yet what I’ll do. I might buy a CT-X3000 or PSR E463 again if I don’t find something more suitable.
By the way, after a few months, what do you think of the PSR S670? Do you like it better than the PSR E453?
Vinciane.
