Hi Godfrey,
The pre-production models I heared in the two official Roland demos I visited didn't have the final version of the O/S nor did they have all the styles on board yet.
According to the staff of the music store the boards had in fact only about 35 of the 300 styles that will be available in the production version.
I wasn't impressed by the quality of the styles I heared in the demo's. Not that was bad in any way. But the factory demo I heared on
http://www.rolandkeyboardclub.com/v/prod_detail.php?id=213&pagina=1 with one of the "unplugged" styles gave me confidence that they will be quite alright when the final version is shipped in a few weeks time.
