The term "bug" in relation to software or human health for that matter, means "something is wrong".
When it comes to software it means that the product has failed somewhere in terms of its formal definition (hence user expectation).
Definition is its specification and in the case of the PA4X for example, is a manual with over 1000 pages.
The topics in the forums requesting "potential bug reports" is there to assist Korg (hopefully) to identify and debug their software.
Bugs in software are NOT the "differences" between versions of hardware/software - i.e. new/changed or removed features for example PA3X vs PA4X.
Like most here, I can write a list of things I would like to have on my keyboard plus things I used to have and would like to have again but none of them are bugs even if they are viewed as poor design by some.
I always support and seriously value the views and feedback from others.
As you say there is sometimes confusion due to language and culture differences.
In summary, I am hoping Korg will address these serious problems as it is affecting their arranger future right now - that would be a shame.
The intermittent shutdown-restart is the most serious.
Fingers crossed we will get some news soon.
