utilities like 7zip/Rar/Zip or system default , that treat those files in different ways.
For those that V2 update did not worked , try again the following :
- First of all make sure that you will download the proper OS v.2 for your Pa4X version International/Oriental or Musikant.
(XXX = UPD or PKG , usually newer production line of Pa4X requires UPD format)
- Insert an empty thumb flash drive bigger or equal to 4 GB in front Pa4X USB slot and From Media / format it.
Case 1 : older compressed files in one downloading file :
International OS source : https://s3-ap-northeast-1.amazonaws.com ... S2_PKG.zip
- Click on downloaded file , choose from right mouse click menu to decompress file "here" , choose the whole extracted folder
"Pa4X_OS_and_Resources_v200.XXX" (one of three extracted) and copy it in your USB thumb drive.
- Open copied file "Pa4X_OS_and_Resources_v200.XXX" with your PC/Mac and verify that "Pa4X_OS_and_Resources_v200.xxx"
or "...001-005(006 Musikant/Oriental) monolithic only files are included and not subfolders !
Case 2 : newer splitted to segments downloads from Korg website :
International OS source : http://www.korg.com/us/support/download ... /516/3610/
- download all segments "Pa4X_OS_and_Resources_v200.XXX.001-005(6).zip" in the same level/folder (for instance downloads folder).
- Click on every downloaded file there , choose from right mouse click menu to decompress every file "here"
- If 7zip is your default program , just use "extract" tab !
- Copy all extracted monolithic files "Pa4X_OS_and_Resources_v200.XXX.001" up to .005 (or .006 for Musikant & Oriental) in the root
of formatted USB thumb drive.
Pa4X BIOS definitely requires all splitted to segments files to be in the same level and not in subfolders , so the contents for Upgrade
must be the following !
- Insert USB stick in Pa4X slot , enter in Pa4X update mode , browse USB stick for "Pa4X_OS_and_Resources_v200.XXX" folderexample wrote:(XXX = UPD or PKG)
Example of the right splitted to segments files format :
Pa4X_OS_and_Resources_v200.XXX.001
Pa4X_OS_and_Resources_v200.XXX.002
Pa4X_OS_and_Resources_v200.XXX.003
Pa4X_OS_and_Resources_v200.XXX.004
Pa4X_OS_and_Resources_v200.XXX.005
Pa4X_OS_and_Resources_v200.XXX.006 (Musikant and Oriental only)
Example of the right non splitted file format :
Pa4X_OS_and_Resources_v200.XXX
open it (in case 1) and in both cases , click on file "Pa4X_OS_and_Resources_v200.xxx.001" choose the only option "Format & Reset"
and proceed to update system will verify the integrity of all files (time is depended from media read speed) , then will ask you to restart
Pa4X and update will finish after 16-17 minutes.
If you still get message "files are invalid" , then either files are separated in subfolders nor have further decompression that needed !
Remember that a succesfully decompressed file is never corrupted , so re-downloading is a time wasting !
You can also DIY , copying all those extracted files in separate folders , in the same folder/root and then Upgrade
clicking on any of them , There is no incomplete/wrong upgrade ... system will check everything and if upgrade
procedure will finish then all are done in the proper way !!!
As the epilogue , the last available downloading file there , out of main OS files , called "Pa4X_OS_Documentation.zip"
includes among PDFs the "Pa4X v2 User Resources.set" that has the newly added resources STYLES & KEYBOARDSET
that are very useful in case that your Saved.SET has overwritten those new resources , since all were placed in User positions !
Hope this helps
