35) The Aftertouch
Apparently not everyone
understood what I wanted to communicate about regulating by the dip or blow
priority methods. Whether a technician chooses one method or the other, the
results will be the same. Some piano technicians get the impression that
depending upon whether the dip priority or the blow priority was used, the
regulation would come out different. This is not the case. When regulating by
the dip priority method, the technician must regulate completely a few sample
keys to prove out by aftertouch that the distances for the dip and blow will
work. Likewise when regulating by blow priority method. I have stated in the
past why I like to use the blow priority method. These reasons will be
restated, along with some new ones concerning the use of a key dip block.
Referring back to the
grand regulation chart printed in the After Touch post, only two steps affect the
blow distance while five steps affect the dip. Of these steps, the key height
affects both the dip and the blow. Regulating the key height was step no12 in
the 50-point checklist, so it should not interfere when getting to section IV
The Touch at step no31. This leaves only the jack height to affect the blow
distance, while four steps still affect the dip. These four are the blow, jack
alignment, let-off, and the drop. Remember that I always include the correct
aftertouch measurement when discussing the dip.
What we want as the end
result is...
