[sdiy] Hammond Vibrato Scanner

[GRAHAM ATKINS]

I quite agree Roy, we need to remember the techniques even if we find
newer or different ways of implementing them. Talking about organs and
why we use synchronous motors historically, It reminds me of a little  
known
rock keyboardist from the late 70's called Bo Hansson. He got his  
keyboard
tech to replace the synchronous motor with presumably a controlled DC  
motor.
The control incorporated a "wheel" to add or subtract to the motor  
voltage to
create ?.........Yes, a Hammond with pitch-bend !.
