Thanks George. User Styles, 64 polyphony, 16 track song recorder, muting style tracks, guitar in styles sounding much better and ofcourse expandibility of 16MB... All in all good improvements over the previous one. Is the expandability about loading only what Yamaha supplies or some of our samples(converted to Yamaha voice through some provided software) can be loaded too ? I`ll need to check out the manuals.
