ABSTRACT:
Disclosed is an electronic piano circuit arrangement which combines a multitude of different frequencies within a resistordiode matrix array. The resistor-diode coupling elements provide a different value impedance for various signals to be combined and the amplitude of the signals are predetermined to electronically produce a piano sound which substantially corresponds to the sound of an actual piano tone.
