There is already a free, independent User's Forum (several, actually) at the Danish site (now in English, German and Danish!)
No manufacturer's censorship (hurrah!), but a tacit presence by the G70/E80 development team. A member recently visited their headquarters in Italy, and they acknowledged regularly monitoring the site for user feedback and ideas. Pretty good, eh?
Other than Ralph Schinck's monthly short Tips and Tricks column, there is nothing at the site other than manuals and demos you can find elsewhere, and MidiSpot's sales portal for styles and songs (also at their own website).
Perhaps things may get better in weeks to come (one can only hope!) but things need to get a LOT better before Roland Keyboard Club can compete with similar Yamaha sites and even the independents.
