Or "gain" if you prefer. When digital pianos are discussed or reviewed the action and the tone are usually considered separately: but touch and tone are intimately related. A third factor, rarely discussed, is volume.

As you turn up the volume the touch seems to get lighter. Of course it doesn't really, but the effect is real enough to affect the way we play.
Feel free to shoot me down.
