I made my own drivers for my XV2020 using another driver sound module. I changed some identifiers in the files contained in the Roland package driver.

All these sound modules are usable with biab using a midi usb interface (but you won't be able to edit the patches with the Roland XV Editor).
Free tools for Biab:
Biab Scales and BIArpeggio to practice scales/arpeggio
Biab Explorer: the other song picker
