What to do if song play cuts out during SMF play on Casio Electronic Keyboard?
- P
  Phillip RichAug 17, 2025
  To resolve the issue of song playback cutting out momentarily during SMF play on your Casio Electronic Keyboard, consider the following: * Perform a 'save as' operation to save the data under a different name without deleting the original (fragmented) data. Then, try performing the operation using the newly saved data. * If you saved the data to the card from another location, format the card (which will delete its contents), and then save the data to the card again. Next, try performing the operation using the newly saved data.

  csmithSep 12, 2025
  To address the issue of playback stopping part way through after transferring song data from your computer to your Casio Electronic Keyboard, consider the following: * The problem may be digital noise from the USB cable or power cord interrupting data communication. Stop playback, disconnect, and then reconnect the USB cable to the keyboard’s USB port, and then try playing back the tune again. * If the issue persists, exit the MIDI software, disconnect and reconnect the USB cable, restart your MIDI software, and try playback again.
