Database Manager on December 20, 2011: Identified through online information from Richard C Greene. -- November 2011: Changes to the Dobson organ. The two-level memory system was upgraded to a 100-level system and a piston sequencer. The number of general pistons was increased from eight to twelve and divisional pistons were increased from four to six. In the new scheme the hitch-down pedals that operated the mechanical couplers were replaced with toe studs and are now operable through the combination action.
