"but a big big difference that would make me buy an fp series piano..
the have the option to play a chords and keep that chord in your rhythm..
i mean you play a C major chords and the fp4 piano play your chords(or some notes of the chord) alone..
BUT rd300gx doesnt do that??i didnt found the same option..
it has some rhythms but it doesnt playes your chord..i think you understand what i mean...
so y i must choose rd300gx that is more expensive???"
