Abstract
An electronic organ circuit includes a multiplicity of keyers receiving control inputs from plural shift and store registers capable of operating any given keyer at different levels. The inputs for a given keyer are applied on a cyclic basis and for differing time periods in such manner that the keyer's output amplitude and waveshape vary in response to the number and duration of inputs. A processor responsive to keyboard key and stop actuation supplies information to shift register chains corresponding bit-wise to the operation of keyboard keys, and corresponding, in respect to bits destined for a given register, to the condition of organ stops. Individual registers are then operated on a duty cycle basis and provide outputs of selected duration for effecting different stop sounds.
