Organ performance supporting device

Claim 1

A performance supporting device for organs, comprising: means for detecting ON signals of actuating switches of combination units to provide control code signals; means for setting signals indicating the individual operative states of the switches by the switch-ON signals; a first read-only memory having stored therein coded control signals necessary for presetting and selection of registrations and selectively reading out therefrom the coded control signals in response to the detected control code signals; means for decoding the contents of the first read-only memory to produce control signals; a registration memory composed of a writable memory capable of storing therein a plurality of registrations and a second read-only memory having stored therein registrations; a first register supplied with a signal from a stop switch and reading out the registration memory in a predetermined operative state to store a registration pattern and the ON/OFF state of the stop switch, the first register having the function of changing its content by the stop switch for setting a desired registration pattern by the stop switch, the output of the first register being applied to the input of the writable memory for storing therein a plurality of registration patterns by a set of stop switches; and means for indicating the state of each of the combination units and the ON/OFF state of the stop switch.
