Strike Sampling:

Strike is the three-dimensional target and principal index of grand regulating. It is the first line on the piano designer's drawing board.

Bedding and Key Level Sampling:

To turn a key into a bedding sample, remove its front punchings, install a Keystep, and turn that up to just touch. The key at rest already contacts both backrail and frontrail. Now it touches all three rails and becomes a gauge for front-to-back keyframe shape. And when key and Keystep make contact on the bench, the keyframe under that key will be the same shape as it was in the piano. Add correct strike and that note will regulate as if it were in the piano.
