    processor.
I read about these beasts in an old Keyboards-book called "Synthesizer 
Technique" (with interesting stuff from Bob Moog, Tom Coster, Craig 
Anderton and others). These animators from Electronotes were 
suggested for string-sound-synthesis    .

I'd love to learn more about them, schematics or information 
available, anyone?!?
