ABSTRACT:
An electronic musical instrument comprises a keyboard circuit providing a pitch determining voltage signal whose magnitude corresponds to the note of a key depressed, a rectangular wave generation circuit generating a rectangular wave voltage signal, and a voltage controlled oscillator connected to receive the pitch determining voltage signal and the rectangular wave voltage signal to produce alternately first and second tone signals for trill performance. The tone pitch of the first tone signal depends on the magnitude of pitch determining voltage signal and the tone pitch of the second tone signal depends on the magnitudes of pitch determining voltage signal and rectangular wave voltage signal. The musical intervals between tone pitches of the first and second tone signals depends on the magnitude of rectangular wave voltage signal.
