I heard one in use last night, and my impressions are that it is the g1000, minus many buttons, some new sounds, and the variphrase. Which means, its not worth it, the g1000 still rules when it comes to live use. I bought a 9000pro, and it sounds muchh much better than both keyboards, but again, for live use, it just doesnt have the features that this g1000 has. I am even THHHISSSSS close to selling it.
Bravo Roland on this classic arranger, but keep in mind some of the things that made the g1000 such a hit, and dont focus on new tricks if its going to hinder live use convenience.
