Abstract
External sound signal coupled through a MIC IN terminal is fed through an operating switch panel section to an A/D converter for conversion to a digital signal. The digital signal is stored in a record memory through a waveform R/W controller under the control of a CPU. The digital signal stored in the record memory is read out from the CPU according to control data stored in a work memory to be fed to an external sound system for sounding.
