Weighing off the action to determine the amount of weight the key requires to move down a defined amount and the amount of weight the key can lift from that point back up to starting point. This information is fed into a program that produces the best hammer and key lead weight for each key. The results are a balanced key board that feels "correct" whether in the low bass or high treble. Currently the piano has an overall heavy touch.
