ABSTRACT:
An electric stringed instrument having an integral accompaniment system is proposed. The vibrations of the strings on the electric stringed instrument are detected as analog signals by a pickup device. A portion of the detected signal is extracted, has its voltage adjusted, is converted into a digital signal, and is read into a CPU as a digital signal within a range of 0-5 volts. An amplification factor of the digital signal is determined according to sound volume data included in accompaniment data stored within the accompaniment system, and the proportion of sound volume between the player's performance and an automatically generated accompaniment is adjusted by multiplying the sound volume of the player's performance, or of the accompaniment, by the amplification factor. The sound volume adjustment is effected only once and only when an automatic balancing switch provided on the instrument is depressed.
