Hi again Sam,

Touch down weight is affected by flange tightness, weight of the hammers, etc. 

In the factory, touch weight is changed with the size and location of lead weights inserted into the keys. The keys in a piano are levers. So, if a lead weight is placed on the key top side of the lever it will make the touch lighter. If it is placed to the back side of the key, it will increase the down weight.

I own two other U1s, (one DKV and one non-DKV) and I really feel this piano is inferior in action and in sound. I'm surprised, as it is relatively unused, the DKV functions work fine, but playing the piano is nothing like the other two and just not a good experience. Very disappointing, as I wanted to buy this for my studio for teaching purposes.
