I am a new user obviously, I own a Korg PA500ORT and I have had so many questions about this keyboard and I've been spending weeks on Google trying to find answers to my questions. I am hoping some of you kind people here can help me

I have several questions, please, if you have an answer for me, I would be so appreciative. One person does not have to answer all the questions, I just want to list them all in one place.
1) My pitch stick use to work perfectly, X and Y axis, but now the X-axis is not working anymore for some reason. I cannot figure out why. I'm hoping it is not broken because my keyboard is out of it's one year warranty, I've had it for about 2years now.
2) I need styles and sounds, or I guess SETS. I am in deep need of them. I work with different ethnic groups, I love all styles of music, I enjoy everyone's talent.
I am in need of:
Greek styles and sounds
Turkish styles and sounds
Arabic Styles and sounds
Persian Styles and sounds
Assyrian Styles and sounds
Khaligi Styles and sounds
It is a PA500ORT, not the PA800, and most sets on google are either fake or for the 800.
3) I want to reorganize the folders, styles, sounds, and performances that are in my OS. When I connect the USB cord to my computer, it only shows me my USER folder

Is there special software that will give me access into the system files so that I can use my computer to reorganize and rename everything? How do people that create new sets do it? It takes weeks to do it by hand via touch screen.
4) Can someone explain how to use the sequencer in this? When I press SEQUENCER, than press RECORD, it gives me 3 options. I usually pick backing sequence to record ideas I have for a song, but of course rough drafts. What are the other two options for?
5) If there is a wonderful drum sequence I would like to use for a song I'd like to professionally record in ProTools, what would be the best way to transfer the drum style to Protools with the accompaniment? Would I have to actually play the song out professionally and record it as one track?
Thank you for helping me out. I know Im asking too much, I don't mean to but I really couldn't find information to answer my questions. I need your help
