Abstract

An automatic performance section and an effect imparting section or (and) a pitch measuring section are provided in combination within a single device, and the operations of these sections are collectively controlled by a processor. To an external sound signal input from outside the device, the effect imparting section imparts an effect designated by designating data. For tuning purposes, the pitch measuring section detects zero-cross points of the external sound signal to measure the pitch of the signal. Under the control of the processor, the automatic performance section, which has automatic performance data and change data stored therein, under the control of the processor, reads out the performance data to perform an automatic performance process and also reads out the change data for changing the designating data to thereby change an effect to be imparted. In addition, there may be provided a process order control section which controls the order of the processes in the pitch measuring and automatic performance sections in such a manner that the zero-cross detecting process in the pitch measuring section is performed with priority over the process in the automatic performance section and that the process in the automatic performance section is performed with priority over a pitch calculating process in the pitch measuring section.
