I spoke with Roland this spring, and apparently the SRJV80 patches that were converted to SRX only work in the 3080/5080/XV88, not the Fantom-S or Fantom-X series synths -- which explains why I couldn't get them to load in my Fantom X8 -- how disappointing. (other vendors like Kurzweil and Korg, maintain compatibility across models when using the same expansion sounds).
In July I picked up a JV-880 and 4 SRJV80 boards (Pop, Techno, HipHop, and House). I'm considering doing a conversion of patches from SRJV80 to SRX but would like to know which boards/sounds people are most interested in. The reason I bought the JV880 was because there's a sound I used to have in my XP30 (long sold) that I need in order to resurrect a song I wrote back in 2002 -- hey, good sounds may go in and out of fashion, but good songs are timeless!
Anyway, I realize that converting these sounds to use on my Fantom X8 will be a laborious effort, which is why I'd like to see who's interested. If i convert one sound per night, 256 sounds times 17 boards equals several years of work. Anyone want to join me on this odyssey? It would be fun to have an additional several sets of patches to use on my Fantom, and if we share the effort, we can share the fruits of this labor. It would be nice if we could use Sysex or software to automate the conversion process, but I don't have all the answers just yet.
For those of you thinking, "Hey, many SRX boards contain the very same samples used in the SRJV80 boards", that's true. but the patches in the SRX boards are different from those in the older SRJV80 boards. Roland may be the kings of recycling old technology into newer products, but usually they do some tweaking along the way.
