You can please some of the people all of the time.
You can please all of the people some of the time.
But you can't please all of the people all of the time.
I observed a similar stream of critically negative comments about the Tyros 5 when its initial specs came out. I remember it becoming quite a downer on several forums to read reactions to the T5 release which I was anticipating especially as I was looking for 76 keys. It seems each arranger/keyboard release is always accompanied by disappointment. So, here it goes again. It's just like with new car buying. You can wait forever for the ultimate car which never comes, or you make your choice when you really need it and get the best that suits your needs and wants at the time. You can only choose from what's available. We're not running the Korg company. They can listen to us but they know who they want to please most and will, via their own research, determine what's best for their goal market. It's a free market. If we want to change Korg's or Yamaha's product development then we have to get an internal job as their development department and direct it. They're doing their customer market research, looking at feedback on these forums, then digest the info and conclude what's the best trade-off in product cost vs overall economic return. Korg and Yamaha will, in the final analysis, proceed according to Ricky Nelson's most practical philosophy: "You can't please everyone, so you've got to please yourself."
