Each to his own. > > David ilvedson, RPT > Pacifica, CA --------------------------------- All of this begs the question, "how much aftertouch should there be?" A good case can be made that neither a dime nor a nickel is correct. Then again either one might be. When discussing aftertouch most people do tend to think of what is happening with the front of the key. What we should be concerned with, of course, is what is happening with the jack. Specifically, with the tip of the jack and its relationship to the hammershank knuckle. This relationship depends on a variety of factors including the hammer blow distance, the overall key-to-hammer lever ratio, the jack letoff distance and, most specifically, the length of the jack lever. Aftertouch -- whether it be a natural key or a sharp -- should be set so that the jack clears the knuckle when the key is fully depressed. That may be 1.6 mm (a penny's worth), it might be 1.8 mm (a nickel's worth), it could be 1.4 mm (a dime's worth) or even 1.7 mm (a quarters worth). Usually it will come out to be somewhere between 1.0 and 2.0 mm. -- ddf
