ABSTRACT:
An improved system for increasing the loudness of any single note selected by playing more than a single key. A command circuit responsive to manual control, including stop tabs, enables a tone signal to be produced in response to the playing of one key or in response to the simultaneous playing of a plurality of keys on a keyboard. Means are provided for changing the relative amplitude of a tone signal produced in response to the simultaneous playing of a plurality of keys with respect to the amplitude of a tone signal produced in response to the playing of a single key.
