US Patent 3,986,423 is the patent for the Oberheim FVS/EVS SEM
polyphonic keyboard scanner - without a cpu.  Dave Rossum is the
inventor while Oberheim Electronics is the assignee.

Had to study it for a FVS I have in for repair.  Crazy system, took me
multiple reading sessions to as my brain got full every few pages.
