PURPOSE:To indicates that the rest storage capacity is small with a sound generation control data output sound when the write quantity of musical information or the rest storage capacity reaches a border value. CONSTITUTION:Automatic performance data AP are written in a sequence RAM 17 in order and when the rest storage capacity is smaller than 1st border data BO1 and larger than 2nd border data BO2, intermittent cycle data TC of a one-second cycle is set in a latch 8 and a piezoelectric buzzer in a sound generating circuit 60 sounds intermittently in one-second cycles; when the rest storage capacity is less than the 2nd border data BO2 and larger than 3rd border data BO3, intermittent cycle data of a 1/4-second cycle is set in the latch 8 and the piezoelectric buzzer sounds intermittently in 1/4-second cycles. When the rest storage capacity is smaller than the 3rd border data BO3, intermittent cycle data TC of a 0 second cycle is set in the latch 8 and the piezoelectric buzzer continuously sounds. |
