Styles are another matter... Yamaha LONG promised it's USB and web connectivity would supply the buyer with an endless supply of new styles and registrations, but have largely failed to live up to that promise. User styles abound, and that's a good thing but it would be nice to see a few more factory quality styles being available...

What is it now? Three years since the T2's introduction? How many new factory styles have become available (and how useful are they)?

One of the upsides to being an early adopter of a new generation arranger is that, as new models start to come out, all THEIR ROM styles can get used either directly or with tweaking, and there is a healthy supply of new styles...
