Abstract
An automatic accompaniment apparatus which has an auto-bass circuit and an auto-arpeggio circuit. In the auto-bass circuit, note information concerning one kind of code is stored in a memory (ROM), and a code signal is detected from depressed key information in a code detector, and in a note converter a note signal from the memory is converted by the code signal to a note signal corresponding to the kind of code, whereby note signals of various kinds of codes are generated. In the auto-arpeggio circuit, note information concerning one kind of code is stored in a memory (ROM), and a code signal is detected from depressed key information in a code detector, and in a note converter a note signal from the memory is converted by the code signal to a note signal corresponding to the kind of code. The note signal is added with a root signal from the code detector, and by the added output, a scale signal is selectively obtained, which scale signal is frequency divided by an octave signal from the memory. Thus, various kinds of codes ranging over several octaves are obtained.
