Abstract: A special circuit arrangement intended for use with electronic organs and the like, and particularly intended for use with electronic organs having playing key operated switches and in which at least a portion of the switches actuated by keys of a keyboard are encoded into binary words during playing.The circuit of the present invention, in particular, is a debouncing circuit which prevents the acceptance by the organ system of a false binary word from the encoder which can be created by the bounce which is inherent in mechanical switches of the type employed for being actuated by the keys of the keyboard.
