PURPOSE:To reload and execute quickly a breakdown program by reading out a program of a sound sequence and writing it in an external storage device of an abnormal sequency, when abnormality is generated due to breakdown of a program of the external storage device. CONSTITUTION:For instance, when an abnormal interruption is generated due to breakdown of a sequence program of a CPU 1a side computer, an abnormal interruption processing routine is operated by a CPU 1a. First of all, a program information which is being executed when the abnormal interruption is generated is fetched. Basing on this fetched information, the corresponding program is read out from other sequence external storage device (called a bulk memory) 2b through a channel 6a. The read-out program is written in a bulk memory 2a of the own sequence basing on the program information, and the breakdown program is reloaded. Subsequently, this program is restarted by the own sequency and the processing is ended. |
