<DIV><FONT face="Arial Narrow">Well, yes, but at the Little Red Schoolhouse,
they pointed out that in order to regulate a grand action, you first have to
have some drop and some repetition spring strength. Then you can work thru
a circle of blow, let-off, drop, dip/aftertouch, backcheck, repetition spring
strength, jack height (winking the jacks) and keep going around that circle or
thru those seven steps until there's nothing left to adjust.</FONT></DIV>

<DIV>I don't know about Potter or Reblitz, but if you regulate according to
the Yamaha 37 steps you'll have some problems. Spring strength affects almost
every other regulation point; if you don't do it very precisely first, and
then refine it later on, thing will change, and not for the better; wrong
spring strength (too little or too much) will blur and confuse the feeling of
the other precise regulation protocols.</DIV>

<DIV>Blow distance, some aftertouch, then spring strength. Foist and fawmost,
kiddies. Balance is the key.</DIV>
