Chatty:
Mine will probably not be the most informed reply, but just so you don't think you're being ignored . . .
I've never figured out SoundDiver. I've had success applying reverb to some patches on my JV-1010 through my sequencing software, but it'll only work if the patch itself doesn't use reverb pre-sets, which many do.
My advice is to get a reverb unit. Although I'm very happy with my JV-1010 overall, I've stopped asking it to do everything well, and we're both happier for it.
