Refill patches from Fantom X to juno G?

Nope; the waveforms on the Juno-G are numbered differently, which means that even if you manage to load Fantom patches into the Juno, they will probably not sound the same. You can try though; someone said that patches that use only Bank A waveforms on the Fantom will work on the Juno.

You can download free Juno patches from http://www.rolandclan.com/library/juno-g
(I love the XV collection!)
or buy commercial patches at http://www.sinevibes.com/juno-g

i picked a handful of the xv collection and put them in my user
area. those sounds are pretty darn good. I just wish you were able to
get the sounds off the srx cards (since they are no longer commercially
available) into an editor and use them. heck you can download all the
d50 sounds you want. I especially want the ultimate keys edition but
don't feel like paying 250 plus for it.

if anyone hAs a good solina string sound let me know

thx

It's impossible to download the SRX sounds because they use wave data which is on the card and not the synth.

interesting. didn't know that. a beginner when it comes to the complexities of it
all. guess I'm stuck buying the card if I can find it for a good price

thx
