Sound on PX-560 is sour all of a sudden and I don't know why, I thought maybe I hit a button while playing
Get same sour sound from internal speakers and headphones
It's set at 440.0 and I've performed a reset 😞 but it didn't resolve
The needle on guitar tuner displays either flat or sharp on the E, A, D, G, B, D tones. Usually they are dead on correct with 440.0
I believe the tone starts out correct but then flattens or sharpen quickly
Overall speaker volume has decreased and have to turn the volume knob higher than usual.
Also tried a lot of different tones, not just Grand Piano, but that's what I use the most. Tones are about off about a quarter step or more, not a full tone up/down
I've shut off the two wheels on left side via the screen, in addition Temperament and Stretch Tuning but still same sound
I can send an audio recording if need be
I've had this keyboard for three years with no issues and I've never moved it or used for live shows elsewhere
Same sour sound when playing a .mid file I recorded
Firmware is up to date - 1.16
Thanks for listening,
Music on Piano
