XML files for Cubase 11/12

Hello, Does anyone have a working XML for Mac for the Yamaha Montage, Korg Kronos or Roland XP-80?

I’m trying to get those instruments to work with Cubase 12 LE AI Elements on a Mac. The txt files I have found in various places are not recognized when in the Inactive folders. Only an XML file seems to import now- I did it successfully with a Kurzweil PC3X Xml file I found online . Online txt to XML converters have proven ineffective. Even if you pull a .txt file out of the Cubase internal patch list folder to your desktop, the system won’t recognize that if you try to import it.

Thanks for any help or suggestions.
