    On older pianos, they usually can't be separated, that is, you have to
recondition the action parts first and maybe do some repairs before you can
regulate.  And often you have to do a quick rough-in regulation just to get
things in the right neighborhood before you can fine regulate -- like a
pitch raise.  On a new piano fresh from the factory, once in a while you
might be able to just turn regulating screws and add or subtract a few paper
punchings here and there, bend a few wires or springs, etc.  But even that
is rare.  Many of them require re-pinning of parts, alignment, hammer mating
to strings, voicing, and other prep work that the factory should have
finished but didn't.
