SUMMARY
The Yamaha PSR-E473 electronic keyboard, manufactured in 2024, has been reported to go out of tune, specifically 1% flat, requiring users to adjust the tuning from A 440 to A 444. This phenomenon raises questions about the reliability of digital tuning mechanisms. Users are advised to check functions 55 through 58 in the user manual to ensure proper settings. The issue may stem from physical component sensitivity, as indicated by a 23-day cycle of tuning fluctuation.
