I've just spoken with Yamaha and they're going to send me an S950 down for a full review and test. It will cover home use, teaching and gigging over a few weeks. same sort of thing that I used to do for Keyboard Player magazine, but the results will be available here, on a couple of other forums and my website.
It will be open, full and honest.
First impressions of the keyboard are good, having played one for a half hour or so at the shop. Some good new sounds, though it's a pity they haven't put some new choir and vocals on (I foresee an expansion pack for these!) and the audio styles are great. The layout and design are always going to be a matter of taste as well as ergonomics, but I quite like the tighter layout. Black? Well, black is the new silver. I'd have preferred silver, but that's the way it's going to be for a year or two no doubt.
I'll pop back with some more interim findings in advance of the full review.
