This is in reference to regulating so that the action is shifted only slightly, to change the tone, rather than all the way onto the right two string grooves. ...<< As I recall from convention time Bosendorfer's philosophy is to shift the action just enough to change the tone. Steinway's states "...when the keyframe is in its shifted position, the left string of the trichords is missed by the hammer". But Steinway also goes on further and says, "...a minimal shift is also acceptable so the player uses only a different part of the hammer during play. This results in a tone of different color, rather than a change in volume...". (Steinway & Sons Technical Reference Guide, page 45) Keith A.
