ABSTRACT:
An electronic tone generator includes a signal-generating oscillator, a memory circuit for storing tone and time data for each note to be produced and two note producing circuits, each including a first programmable counter electrically connected to the memory circuit and the signal-generating oscillator and for variably dividing signals outputted by the signal-generating oscillator in order to sequentially produce notes of predetermined frequencies and durations according to the data read from the memory circuit. The note outputs of the two note producing circuits are interrelated to produce a music effect.
