37 steps

[David Nereson]

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.

  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.


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