Abstract
A synchronizing signal generator generates synchronizing signals in synchronism with the performance of a musical piece even from an intermediate point of the musical piece. More specifically, upon actuation of a manual switch (102) in accordance with a musical piece, a code signal corresponding to a beat number is recorded in a tape recorder (200). At the same time, a clock counter (112) counts clock pulses during a period of time from the point where a code signal corresponding to the beat number is received to the point where the next succeeding code signal is received. A CPU (105) divides a count value of the clock counter by a predetermined numerical value so that a value obtained by the division is stored in a memory (114). When the recorded code signal is reproduced and applied to an input terminal (101), the CPU identifies a beat number from the reproduced code signal and delivers a step number signal corresponding to the beat number and a sequencer start signal to a sequencer (300). During a period of time from an identification of a beat number to the identification of the next succeeding beat number, the clock counter counts clock pulses and the CPU provides synchronizing signals when a count value of the clock counter becomes equal to the value stored in the memory.
