How to fix the off pitch on Casio AP-450?
- Bbrittany03Jul 28, 2025
If the pitch of your Casio Digital piano sounds off, try these solutions: * Check that the key setting is at “440.0Hz”. If it's different, change it to “440.0Hz”, or turn the power off and on again. * Adjust the digital piano tuning, or power cycle the piano. * Ensure that the octave shift setting is set to “0”. * Confirm the temperament setting is set to “00: Equal”, the standard modern tuning.
