Welcome to the forum.

There is a PA900 section where this question might be better asked.

Does the stuck note issue occur when everything has been disconnected, apart from power and headphones? Does it happen with all sounds?

It does it plugged into the pa system, and just thru the onboard speakers during practice. I used to be able to press shift.end and go on, but now it Will even reboot in this condition. It
Is an intermittent issue increasing in frequency.

This seems like a hardware problem rather than a software one...
Can you record a video of it getting stuck (with sound) so we can say something maybe more specific?

Do you have good power going into the instrument at your location? Are any other electrical devices suffering weird operations? Are you under warranty? If under warranty, document occurrences and get it checked out. Good luck!

Well the psu inside pa900 (and most others) is a switching mode power supply which means that is ll run with at least anything between 90 and 250 volts..
I highly doubt it is the input power the problem..
It could be the psu itself having not stable voltage output but this is a hardware fault too and needs the keyboard to get disassembled..

I use a power conditioner, and have had it for a couple of years now. No warranty hopes. I see many posts on this issue, hard to believe it's hardware. My old i5s still works perfectly, that's why I bought another korg. I can't express my disappointment. I buy the power supply as it did it once in a while when new, I dismissed as firmware. Now it's too undependable to play live, and even fails in my studio now. The main problem is I love this board.

Have you tried factory restore and play with only the factory styles (don't load any set) to check if it ll do it again?
