I had the VR09 for quite a while. Playing the VR730 was a completely different experience. Huge improvement over the VR09, just incredible. Couldn't believe it's the same sound engine. It not only felt like a completely different instrument but it also sounded different, and yes, much better. This is true for the Rhodes sounds in particular. These are based on the Roland Classic EPs expansion boards after all. The piano playing experience on the VR730 was definitely on par or even better than the spring modded Artis 7 which I also owned for a couple of years. The Artis 7 action with original springs was way too stiff for my taste.
