Storage means for storing a pitch code and a time length code corresponding to each note as data of an automatic performance pattern, and storing only a time length code corresponding to each rest, and reading from the storage means a time length setting means for setting a time length according to the time length code read from the storage means; a musical sound signal creation means for creating and outputting a musical tone signal according to the pitch code read from the storage means; determining means for determining whether the time length code corresponds to a musical note or a rest; and said time length setting means when the determining means determines that the time length code corresponds to a musical note. The musical tone signal generation means is controlled to output a musical tone signal for the time length set by the time length set by the time length setting means when the time length code is determined to correspond to a rest. 1. An automatic performance device comprising: control means for controlling the output of musical tone signals from said musical tone signal generating means for a length of time.
