Abstract

Abstract A registration affecting system for electronic or pipe organs which provides for monitoring, storage and output actuation of stop and coupler key combinations selected by the operator of the organ. The translated outputs of organ pistons are input and scanned along a common data buss by a central processing unit. The central processing unit determines which registration aid function is being requested by the organ operator and causes actuation of the specific stop combination stored in a memory module. Upon a determination of the proper states of the stop and coupler keys to be actuated, the central processing unit initiates output actuation of the appropriate stop and coupler keys to select the tonal quality required.

Claim 1
Independent Claim 270 words
An organ registration affecting system for use with electronic and pipe organs having a plurality of pistons and a plurality of stop and coupler keys and a plurality of actuators for setting and resetting the stops and couplers, said system comprising: a. input interface means for translating and presenting signals responsive to a selected piston, the state of stop and coupler keys and engagement time of the organ actuators; b. output interface means for setting and resetting the states of selected stop and coupler keys and actuators; c. a central processing unit including a program counter, address register and arithmetic and logic unit and input and output means for transferring data to and from said central processing unit respectively, said input means being coupled to said input interface means and said output means being coupled to said output interface means; d. read-only memory means for program storage, said central processing unit input means being coupled to said read-only memory means; e. random-access memory means for storing data correlating the signal responsive to a selected piston and the selected actuator, the input and output means of said control processing unit being coupled to said random access memory means; and f. at least two pages of working registers, each page comprising eight registers of two bytes each, said working registers being coupled to said arithmetic and logic unit of said central processing unit whereby a selected organ piston causes said central processing unit to correlate said piston with signals responsive to selected stop and coupler actuators, said signals responsive to said actuators being output to the organ by said output interface means.
Claim 2
Dependent Claim 270 words
An organ registration affecting system for use with electronic and pipe organs having a plurality of pistons and a plurality of stop and coupler keys and a plurality of actuators for setting and resetting the stops and couplers, said system comprising: a. input interface means for translating and presenting signals responsive to a selected piston, the state of stop and coupler keys and engagement time of the organ actuators; b. output interface means for setting and resetting the states of selected stop and coupler keys and actuators; c. a central processing unit including a program counter, address register and arithmetic and logic unit and input and output means for transferring data to and from said central processing unit respectively, said input means being coupled to said input interface means and said output means being coupled to said output interface means; d. read-only memory means for program storage, said central processing unit input means being coupled to said read-only memory means; e. random-access memory means for storing data correlating the signal responsive to a selected piston and the selected actuator, the input and output means of said control processing unit being coupled to said random access memory means; and f. at least two pages of working registers, each page comprising eight registers of two bytes each, said working registers being coupled to said arithmetic and logic unit of said central processing unit whereby a selected organ piston causes said central processing unit to correlate said piston with signals responsive to selected stop and coupler actuators, said signals responsive to said actuators being output to the organ by said output interface means.
Claim 3
Dependent Claim 94 words
