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. The keybed is a distance from it, the bridges, agraffes and capo bar, the hammer centers, wippen centers, capstans, key pins, and keys. For the regulator, hammerline, letoff, drop, key level, key dip, backchecking and aftertouch all relate to strike. And, of course, correct placement of strike in our bench setup critically impacts how our work will fit in the piano.
