A TONE GENERATION SYSTEM FOR PROVIDING AN OUTPUT TONE OF GIVEN CHARACTERISTICS FROM A KNOWN INSTRUMENT HAVING AT LEAST ONE PHYSICALLY VIBRATING ELEMENT FOR GENERATING THE NORMAL SOUND OF THE INSTRUMENT, COMPRISING, IN COMBINATION; TRANSDUCER MEANS FOR CONVERTING THE PHYSICAL MOTION OF SAID VIBRATING ELEMENT INTO AN ELECTRICAL A.-C. SIGNAL OF PROPORTIONAL AMPLITUDE; WAVE SHAPING CIRCUIT MEANS CONNECTED TO ECEIVE AND CONVERT SAID A.-C. SIGNAL INTO AN OUTPUT SIGNAL OF GIVEN WAVE SHAPE AND GIVEN FREQUENCY; AMPLIFIER MEANS FOR SAID OUTPUT SIGNAL; REPRODUCING MEANS FOR CONVERTING SAID OUTPUT SIGNAL INTO SAID OUTPUT TONE, SAID GIVEN CHARACTERISTICS OF SAID OUTPUT TONE BEING DETERMINED BY SAID GIVEN WAVE SAHAPE AND FREQUENCY; AND, CONTROL MEANS REPSONSIVE TO THE AMPLITUDE OF SAID A.-C. SIGNAL TO PROVIDE A D.-C. CONTROL VOLTAGE WHICH IS A FUNCTION OF SAID AMPLITUDE, SAID CONTROL MEANS BEING CONNECTED TO APPLY SAID CONTROL VOLTAGE TO SAID AMPLIFIER MEANS TO VARY THE BIAS OF SAID AMPLIFIER MEANS WHEREBY THE AMPLITUDE OF SAID OUTPUT SIGNAL VARIES IN ACCORDANCE WITH THE AMPLITUDE OF SAID VIBRATING ELEMENT.
