Well, I sent an email including a link to this thread to the top people running the Kaces company and also to the music store that I bought the case.
Kaces responded in a very helpful manner. They are currently checking out to see what may have happened here with the size of their cases. No intentional size change was made in the designing end of it. They will be checking with the factory to see if there was some change that took place there.
They even offered to get me the next size up case for the same money even though it is a bit more expensive. I unfortunately had to decline because of the lenght.
They are going to take the Tyros off the list of what case fits what keyboard until they have a handle on this.
So, here we have a company with good customer support trying to make things right.
I am hoping, and I'm sure along with the other Tyros owners that they, or somebody comes out with a case that will fit all the Tyros keyboards without excess length, weight, etc, etc.
