Í just received Roland's answer. They are not helping at all. Unless someone else finds a way to convert the patches, we'll remain where we are. Here is their answer:
Greetings / Salutations!,
The data reproduction for the SR-JV Series cards are only available to certain Roland products (listed below, from an excerpt from the SRX-07 Owner's Manual).
Due to advancements in synthesis technology and file structure, the Fantom-X Series are not among the Roland Products that can directly reproduce the original SR-JV Series patchs. Keep in mind that the "Fantom" listed in the products below refers to the original Fantom FA-76, released in 2001 (which had both SR-JV and SRX Series expansion slots).
Most of the original SR-JV patches do exist in the SRX patch list (Patch List for Fantom Series keyboards are listed on page 6 of the SRX-07 Ultimate Keys Owner's Manual). Some patches may sound slightly different on more recent keyboards and synthesizers due to advancement in the effects engines.
