<div>In a blind test (not double-blind) I put Crescendo punchings on a concert D at my university.The pianists didn't know what I had done, or indeed that I had done anything -- but they didn't like it.</div>
<div> </div>
<div>I left the Crescendos on for several months. I finally removed them, because there was general dissatisfaction with the piano. With the original punchings restored, again without telling anyone that I had done anything, there were many compliments about how the touch improved. I thought that one of the functions of the key punchings was to cushion the blows to pianists' fingers, and that without sufficient cushioning, playing will be uncomfortable. I don't think Crescendo punchings provide sufficient cushioning; I suspect that they can make playing uncomfortable for the pianist.</div>
<div> </div>
<div>I don't use Crescendo punchings. Sorry.</div>

<div>In KC I did a test with a small group of techs. Using samples</div>
<div>from Jurgen, we compared the original punching to Crescendo</div>
<div>straight-sided and conical-cut punchings.</div>
<div><br></div>
<div>The consensus was that the straight cut produced a slightly better</div>
<div>tone than the original and the conical cut punching was better than that.</div>
<div>However when we turned the conical punching over (narrow side on bottom)</div>
<div>the tone diminished.</div>
<div><br></div>
<div>So the orientation of the conical punching is critical. Which was why on those</div>
<div>Asian uprights, I could notice a difference playing chromatically. A simple fix :-)</div>
<div>However, conical punchings are not suitable for all verticals either.</div>
<div><br></div>
<div>On a 3 y/o S&S S which needed the key travel to be increased I recommended</div>
<div>the Crescendo punchings and made a test on C4. The piano owner was surprised</div>
<div>how much the tone focused when the new punching was installed, "That wavering</div>
<div>went away", she said. The action felt better too with a more positive landing to the key.</div>
