Dave,

The 9 stack comes out from how deep you press the keys. The word
"pressure" may be misleading to some, and was meant as "depth" (how
deep or shallow you press the keys) not as pressure on a synth where
envelopes can trigger vibrato for example the harder you press at the
end of the key's travel. As you did mention, pressing "part way down"
is how to work this feature. But when you play this feature in a chord,
the different tones in a stack will mix with the other notes' stacks
depending on how far down you pressed your index finger for example in
relation to your ring finger or thumb etc. So rather than play a
console Hammond like a piano, variations in the depth of each key
pressed produces this 9 stack effect and is a feature that is exclusive
to a real B3 and not available on any clone that I know of.

Huh?

You are not saying the keyboard is pressure sensitive, are you? It is
not.
The tonewheels are loosely spring coupled to shafts that rotate at
different
speeds but which are locked together with gears.

So the wheel itself runs at a constant average speed, but is free to
fluctuate speed slightly. This causes the constant tiny changes in phase
between wheels which keeps them from sounding static and dead.

But it has nothing at all to do with key pressure. You can control the
spread of the key click by the speed you press the key. And you can
cause
some of the harmonics to sound by themselves by carefully pressing the
key
part way down.
