I have an inexpensive Yamaha , and I'm pretty happy with it. It has touch sensitive keys: soft, normal and hard. The action is similar to a very lightly weighted piano. But then I hear other folks raving about their weighted keys like the ones in the Casio CDP100, and suddenly I feel inferior, even though I am perfectly happy with my DGX 505. So my question is this; is there a way to adjust keys to make them weighted? Does anybody have any suggestions or know any tricks?
