[sdiy] hammond again

Thanks to all who replied, on-list and off-list.

I think I wasn't clear enough about this. 
I was neither talking about slow lesley effect / chorus vibrato, nor
did I expect any effect back to the motor.

I was talking about the tonwheel / pickup system, back to a
mechanical junction where there is no stiff coupling to the motor.
I think there is a resilent part in there somewhere, which would
certainly form a system which can "oscillate" against its nominal
rotation. Also, a sudden loading of the system will certainly cause
such oscillation, if ever so tiny.

My question is: would this be a *perceivable* effect??
I have no idea how to quantify this.

Again, what I was talking about was not a "chorus" type of sound.
It's more like "liquid" versus "dry".
The funny thing is that samples of a tonewheel organ often *have* this
liquid character, but an electronic drawbar organ doesn't have it.
