If you already have a Tyros4, like Tony, for instance, with the addition of Kronos, you have the best of both worlds.
I was actually hoping the Jupiter 80 would be a super digital version of the Jupiter 8, with enhancements of course, but it isn't...sounds great, but, for my money, I'd go for the Kronos.
