What puzzles me is that in over a year of gigs and rehearsals my Pa4x has been stable. The last session I done the Pa4x was playing back one of my midi files a file used lots and during this playback suddenly the instrument locks up leaving all panel controls frozen but with the midi file continuing, no sound available across the keyboard either. I cannot fathom this and thinking back to the freezing issues with the Kronus owners who were gigging with it were using a UPS power supply, maybe mains issues are also a issue for the Pa4x and lets remember which uses a common garden PC motherboard?

Pa4x doesn't have a pc motherboard.
It uses the same architecture as pa300/600/900/3xle...
I can't be sure but from what i have seen and given how new is the 4x still, i don't think that this is a power issue.It should be a software one or fault in flash memory on cpu board.
System does something like defragmenting on flash to keep it in good shape every X runs or X days (don't remember the exact numbers right now).So i give most possibilities that it is a software error...
As there is no factory reset os (at least yet) ,you can try to recreate the problem and post how every user could recreate it (exact steps like 1)open a midi file,2)choose a performance,3)open another file , etc...) so other users and/or korg will be able to investigate and find what is causing it!

Regarding the PC motherboard your right I thought I seen a breakdown picture of the innards of the Pa4x showing such a configuration my mistake.

Regarding the freeze up this last week of extensive testing has failed to replicate the issue but that said with a heavy month of live work coming up let's see what gives.

After some heavy gig schedule following the lock up I reported I have not experienced any further such issues so the lock up remains a mystery

Long may it continue I say

Is the operating system in the flash memory and if flash memory is the same as a USB memory stick than it should not need to be flashed until you update to a new operating system.

As I said before the only time the keyboard would freeze up is with operating system124 and only in the songbook mode . but now I'm Back to os121 , and no more freezing up.

It could be anything. All it takes is a hickup in the OS or in button presses or a flaky connection to something important inside to create a lockup. I hate those intermittent problems.
