Thank you for the answer. I would try tomorrow to see closer if there is any difference in 256 mode, but at the first glance it does not really fix the issue. Let me know if I can be of help and gather any other information (maybe something can be done from SSH?)
Meanwhile I’ve tried to shoot a video of the tuner glitch, (https://drive.google.com/file/d/1zldu3dWO-dTVyHzJi-8ujplS3n9hjony/view?usp=sharing) and after looking into my recording I’ve ended with these highlights below:
From what I see - numbers are more or less believable, they do not jump like crazy too far away.
But bar indications seem not to match the numbers.
And if I would believe the numbers, then do am not out of tune from 220hz for more than 1HZ in these screenshots, which should be about 8 cents. How many bars that should be? In other words, how many cents are expected in one bar?
Let’s look unto 219.25 hz - it is -5.9 cents away. However it is all 5 bars of indication away from 220. Seems like too far.
Another strange thing - 221.03 showing 5 bars left and 221.01 showing 5 bars right.
Strange for too many reasons, actually.
I can try to record more videos under different conditions, if it may help.
