Without getting deeply into it put more emphasis on a person's talents playing and singing, etc, versus what is the best keyboard, ...... let's face it they basically can all mostly do the same things and sound great if you know how,.. that you as a player have the advantage as a musician to make it sound amazing,... but, most think it's the keyboard that can do all the work for you... not true. Just look in the mirror and say to yourself do I really need this?.. and what the hell am I doing with all of this stuff?
