From the Roland website:
Can I reproduce the original patches of the SR-JV80
Expansion Boards on a Fantom-S or Fantom-X series instrument using the SMF data from the CD-ROMs included with the SRX-06 - 09?
[Outline]
This article explains that the SMF data from the CD-ROMs included with the SRX-06 - 09 cannot be used to reproduce the original patches of the SR-JV80 Expansion Boards on a Fantom-S or Fantom-X series instrument.

Fantom-S / Fantom-S88 / Fantom-X6 / Fantom-X7 / Fantom-X8 / Fantom-XR / Fantom-Xa / SRX-06 / SRX-07 / SRX-08 / SRX-09
This is not possible.
Only the XV series and the original Fantom (models not ending in -S, -S88, -X, -XR, or -Xa) are able to reproduce the original SR-JV80 series patches using the SMF data from the CD-ROMs included with the SRX-06 - 09.
That said (or quoted), I believe that for the SRX-06 too someone here may have produced a conversion for the Fantom X of these patches (I know someone did for the SRX-07). Too lazy to look it up right now.
