I need some advice on Roland sound modules. I used to have one of the Roland JV keyboards (stolen in Philly 6 years ago) and I liked the sounds/setup. I'm looking at the JV-880 or JV-1080, but I'm wondering if there would be any benefit in looking at the SC-88pro or the SC-880. The most important thing to me is the sound. I'll be using whatever module I buy with my Wersi digital piano at live gigs and as a unit with Cakewalk.
