Why is the pitch off on my Casio Digital Piano?

  Wesley NashJul 31, 2025
  If the pitch of your Casio Digital Piano is off, there are several potential causes: 1. The key setting might be something other than “440.0 Hz”. Change the key setting to “440.0 Hz”, or turn the Digital Piano off and then back on again. 2. The Digital Piano tuning might be incorrect. Adjust the Digital Piano tuning, or turn the Digital Piano off and then back on again. 3. A non-standard temperament setting might be in use. Change the temperament setting to “00:Equal”, which is the standard modern tuning. 4. Octave shift might be enabled. Change the octave shift setting to 0.

  If you're not hearing any sound when pressing the keys on your Casio Musical Instrument, there are a couple of things to check: * First, make sure the VOLUME controller isn't set to “MIN”. Rotate it towards “MAX” to increase the volume. * Second, ensure that headphones or an adapter plug are not plugged into the PHONES jack. If something is plugged in, disconnect it.

Why does playback stop when transferring song data to my Casio Musical Instrument?
- J
  Jonathan MillerAug 9, 2025
  If playback stops during song data transfer from your computer to your Casio Musical Instrument, it could be due to digital noise interrupting the data communication. This noise might come from the USB cable or power cord. To resolve this: 1. Stop song playback. 2. Disconnect and then reconnect the USB cable from the Digital Piano. 3. Try playing back the song again. 4. If the problem persists, quit the MIDI software, disconnect and reconnect the USB cable, restart the software, and try playing the song again.
