Electronic musical instrument

摘要

An improved gate circuit to suppress bounce is provided for an electronic musical instrument such as an electronic organ. The circuit includes a gate having a first input from a constant supply voltage through a key actuated switch, a second input comprising a sound signal and an output connected to one input of combining or summing circuit hereafter called an integrator. A second input to the integrator comprises a constant, compensating voltage comprising a portion of the supply voltage. The output of the integrator is connected to further processing stages of the instrument.
