But why would they release an unfinished product? They had 3 years to figure it out. Did they really think there wouldn't be an uproar?? Or did they want the uproar...

Yamaha is following a pattern. They used to be so reliable. But they're leased the T4 with tons of bugs, the s950 needed an update out of the box, and now they release a T5 without a voice creator and no official statement explaining their intentions.

I'm very concerned about what Yamaha actually thinks about their customers. To me it's seeming that they are no longer aiming at the pro-user but at the casual home user.
