Abstract
An automatic arpeggio musical instrument includes a pulse generator having a plurality of keys for generating periodic pulses by depression of one of the keys, each of the keys generating a voltage, a timing pulse generator connected to the pulse generator, a memory connected to the timing pulse generator for generating digital signals of a musical scale, digital-to-analog converter means connected to the memory for converting the digital signals into analog signals, a processor connected to the converter for selectively adding and subtracting the key-generated voltage to the analog signals, and for generating an output voltage therefrom, and a voltage-controlled oscillator connected to the processor for controlling the output voltage.
