I have to agree with David guys. I don't have the Roland JV2080, but I do have the XP60, which is essentially the same thing.

I've never had any problems with the timing of my XP60 period. Never. I never had problems even when I triggered it from programs like Cakewalk or Cubase. And like David, my X also fully loaded.

The 3FX story is a likely one, but I've come accross people who comaplain about this, and people who deny this all the way. I'm one of tghe deny-ers. Sorry all, check the rest of your systems.
