Music sound generating device and control method of music sound generating device

摘要

A music tone generating device comprises: a non-volatile memory device that stores music tone waveform data; a volatile storage device; and a control device which, when switching on a power supply, performs a control to transmit music tone waveform data to the volatile memory device from the non-volatile memory device, in the case in which a command for playing a music tone is issued, the control device reads music tone waveform data from the volatile memory device, and in the case where an error is detected in the read music tone waveform data,the control device performs a control to obtain music tone waveform data obtained by correcting the music tone waveform data with the detected error, overwrite the volatile memory device or transmit normal music tone waveform data in accordance with the music tone waveform data with the detected error to the volatile memory device from the non-volatile memory device.
