Musical tone generating device and control method of musical tone generating device

A musical tone generating device, comprising:

• a nonvolatile storage device that stores musical tone waveform data;
• a volatile storage device;
• and
• a control means configured to,
• when a power supply is turned on, performs control to transfer the musical tone waveform data to the volatile storage device from the nonvolatile storage device,
• in a case where an instruction to reproduce a musical tone is given, the control means is further configured to read musical tone waveform data from the volatile storage device,
• determining whether there is an error detected in read musical tone waveform data;
• when the error is detected, determining whether the error can be corrected;
• and
• in a case where the error in the read musical tone waveform data is detected, and the error can be corrected, the control means is further configured to correct the musical tone waveform data including the error that has been detected, and to perform control to overwrite musical tone waveform data with the musical tone waveform data that has been corrected to the volatile storage device, and
• when the error cannot be corrected, transfer normal musical tone waveform data corresponding to the musical tone waveform data including the error that has been detected to the volatile storage device from the nonvolatile storage device.
