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> <div><br></div> <div>All in a day's work in super-hero-land.</div> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
