As FMDrive VST can also import registers data line directly...
I have recently made a mod with FMDrive support for the Naruto's Hoot Voice Ripper which now let you dump the current track FM presets from Japanese computer FM music, X68000, PC88, PC98 etc..
This will output an .FMD file with a DATA LINE you can directly import into FMDrive

Doing the other way around; FMDrive made track(MIDI) >> X68000 (MDX format) is not easy as one click but is POSSIBLE
