nedsolaud,

Now you sound like a Ketron dealer.
Of course it is not profitable for them to make one keyboard and continue to upgrade it forever.
But, try to think from the consumerís perspective and remember what was promised when X1 was introduced.

Again, I don't care what happened with you GM WK4, that is another brand with different reputation and so on. That why I didn't go for GM. Ketron was recognized as a small but customer oriented company's which differentiated Ketron from big guys like Korg and Yamaha. That was one reason why I decided to go for Ketron. But now it looks that the advantage was "fake".

It is true that there is no single instrument with a perfect OS but I never had hung-ups with my Triton or 9000pro. As I mentioned before, users confirmed X freezing on them when using the flash card or when switching from sounds with aftertouch.
This is far from "the reliable". I am not looking for a perfect OS but for one which will allow me to use all features properly and not hung-up on me in the middle of a gig.

Another thing ...
The industry is changing and the competition is growing. Now the small things, like quality of customer service, expansion capabilities, upgrade capabilities are winning the market. Keyboards are becoming similar in sounds quality and features so the companies are going and extra step to secure the market. That includes things that maybe don't make sense from profitability point of view, like OS upgrades.
I am sure that was just a dream when your old Beetle was released.Times have changes
Btw, auto industry is changing much slower than computer industry ...

The bottom line is X series attracted many customers with the non-obsolesce promise. We all know we can not expect endless upgrades but we deserve to have a stable OS in order to enjoy all features of X series. Now, if X1 was one of the cheap Casio keyboards, I would not expect much, but Ketron is known as one of the most expensive arrangers on the market. I guess a high price should be followed by high quality otherwise who would buy it ?
