In reality, it comes down to what and how you're playing on your keyboard not so much the keyboard it self. For example I'm getting tired of using the same old licks for blues based generas. I realized I am always using the minor blues scale so I'm figuring out how to more musically use both the major and minor blues scale. It's totally changed how I solo over blues, rock, and county styles. It wasn't the keyboard's fault that I was musically limiting myself!
