ABSTRACT:
On a keyboard musical instrument provided with action assemblies each including a catcher and silent assemblies each including a stopper, the real silent distance between each catcher and an associated stopper is measured to calculate its difference from the optimal silent distance, and one or more attachments are added to or one or more components are removed from either of the two elements depending on the polarity of the difference in silent distance in order to minimize the let off distance of each hammer relative to an associated string.
